1 Audience
This document is intended for en ineers evaluatin the TK37XX family of inte rated EPON solutions. The
document explains how to use the TK37XX PC HOST GUI EponSystemApp.exe, for the purpose of evaluatin the
functionality and usability of TK37XX Host Interface Protocol. This manual assumes that the reader has a
technical back round and a base level of understandin re ardin the basic operation of PON equipment, but
does not assume any prior experience usin the TK37XX or any other product. The PC Host GUI is a
demonstration packa e, intended for evaluation purposes only.
2 Organizati n f the GUI
The screen real estate used by the GUI is divided — MDI style — into three sash windows. The upper left panel

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
displays the entities that may be mana ed by the TK37XX Host Interface, includin the OLT, ONUs and Lo ical
Links. This sash window shall be referred to as the Element Status Window. Left clickin on an entity with the
mouse will open a tabbed panel in the upper ri ht sash window that may be used to mana e the entity. This sash
window shall be referred to as the Entity Mana ement Window. The bottommost sash window is used for the
purpose of lo in the host interface messa e that are sent and received by the GUI, and shall be referred to as
the Messa e Lo . The Messa e Lo displays the commands that are sent and received from the GUI as well as the
raw bytes sent and received by the physical layer interface.
2.1 Basic Structure f GUI S ftware
The GUI software breaks down into 4 lo ical layers the first layer is the physical interface. The operatin system, or driver
resource, used to send and receive the raw Host Interface messa es. The next layer consists of the underlyin messa in system
used by the GUI. This layer is responsible for parsin and queuin of Host Interface Messa es as well as providin reliability. The
next layer is the application layer. This layers responsibility is to display the GUI windows and provide services such as alarm
auditin .
2.2 GUI Start Up Sequence
When the user invokes the EponSystemApp.exe by double clickin on the T icon the GUI will perform the followin functions:
EponSystemApp.exe
Step 0: Attempt to establish a UDP connection to the TK3721. This process will continue indefinitely or until the connection is
established.
Step 1: After the connection is established the GUI will test the interface by attemptin to send and receive a host interface
messa e. The natural choice (and the choice that the GUI will use) is the Get OLT Information. This messa e contains information
about the TK3721 that the host may use to identify product version information.
Step 2: Once the interface has been established the next step the GUI shall perform is to obtain the list of discovered links. It
should be noted that once the interface is detected the GUI shall initiate a process to handle autonomous events. Receivin an

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
autonomous event will make the remainin sequence non-linear, as the autonomous events will be inserted into the GUIs
messa e queues with other response messa es, refer to the note on the GUI data path below.
Step 3: Once the GUI receives this list, it will query the links for the identity of their associated ONUs by issuin a Get ONU Info
Host Interface Messa e for each link found in the list. Of course if an autonomous event (such as link discovery), occurs that event
will also be processed simultaneously with the queryin process. If the GUI is confi ured to authenticate its links, the link
authentication will also take place. A ain there is no set sequence and multiple LLIDs may be authenticated simultaneously.
Step 4: Havin discovered the known mana ed entities the GUI will next query the TK3721 for the list of blocked links. These links
will be displayed in the list of unassociated links in the mana ed entity status window. If the ONU is connected to the TK3721 and
operatin properly, then unblockin a LLID will cause a new ONU to appear in the entity status window. The LLID will be
associated with this new ONU.
Step 5: After the GUI has finished queryin the OLT, it will remain in the idle state until the user performs some action. In the idle
state the GUI will audit the OLT for alarm messa es if confi ured to do so, otherwise it will not send any Host Interface Messa es
until the GUI operator directs it to do so, by initiatin a query or provisionin action.
2.3 N te n the GUI data Path
The GUIs Data Path consists of simple non-blockin queuin mechanism that achieves very ood utilization of OLT recourses.
However in such a system there is no set sequence in which messa es will be issued to the OLT. Thus that dependin on very
minor timin differences between command response times, the GUI event lo trace will be different. It is important to note that
all host interface messa es are required to encapsulate a complete set of provisionin operations and therefore do not require
that provisionin actions be performed in any set sequence.
3 Basic Operati n f the GUI
As stated earlier, left-clickin the mouse on an entity in the Status Window shall cause an associated tabbed dialo to appear in
the Mana ement Window. This dialo exposes nearly the entire set of host interface commands associated with the mana ed
entity. The tabs are or anized into rou hly the same cate ories as the TK37XX Host Interface document. And with few exceptions
all of the panels function similarly.
3.1 GUI C ntr ls All controls in the GUI are derived from a common set of base classes and thus operate in similar ways. Most
panels include 1 or two buttons that invoke the GUI to perform various transactions with the OLT. All such controls havin the
same basic function will also be iven the same label. For simplicity of understandin an explanation of each button type appears
bellow.
3.1.1 Apply Butt n
Most GUI panels mana e only a sin le TK3721 Host Interface messa e. Every time the panel is displayed the GUI will
automatically query the OLT for the latest attributes by issuin the appropriate Host Interface Messa e to the TK3721 firmware. If
the query operation is successful the panel will be updated with the latest values from the firmware. As a eneral rule, when the
panel is updated from a host interface messa e the associated Apply button will be disabled to indicate that the values displayed
are an accurate reflection of the current state of the mana ed entity associated with the panel. If an error occurs the Apply
button will not be disabled indicatin that the displayed values are not those of the mana ed entity. Chan in a GUI wid ets value

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
will cause the Apply button to be enabled allowin the GUI operator to apply the new provisionin to the mana ed entity.
3.1.2 Refresh Butt n
Button’s labeled refresh are never disabled. The action associated with a Refresh button is always to query the state of the
associated attribute. The result of a successful Refresh operation will be the same as if the panel is viewed for the first time. That
is, the OLT will query the mana ed entity associated with the panel, and if the operation completes the Apply Button will be
disabled.
3.1.3 Revert Butt n
The Revert Button had identical functionality to the Refresh button, but is semantically different. The idea behind the Revert
Button is that you can “revert” the panel’s state to the initial state of the panel prior to chan in a GUI wid et. Semantically, once
the apply button has been pressed it is not possible to revert. The Revert Buttons are currently bein phased out in favor of the
Refresh Button.
3.1.4 Defaults Butt n
The Defaults Button is used to restore the mana ed entity to the default settin s found in the Host Interface document. This
mechanism employs a “canned” Host Interface Messa e that will be issued to the OLT when the button action is invoked by left
clickin on the button.
For most commands a provisionin operation will also result in a subsequent query. In such cases the Apply Button will not be
disabled until the query operation completes. This audit mechanism ensures that the values displayed by the panel are the same
values stored in the relevant mana ed entity. For a few Host Interface Messa es the ranularity of the data is less than that of the
provisioned value.
Some Apply actions result in multiple commands bein issued to the OLT.
4 GUI Panel Direct ry
This section describes the various panels found in the GUI, their function, and the method by which they may be used to test the
TK37XX Host Interface. The Panels are or anized by entity and enerally follow the order in which they appear in the associated
tabbed dialo box. In the rare case that the GUI abstracts some detail of the host interface, a flow chart of the messa e exchan e
sequence is presented. Where the messa e performs a complex operation on the PON a related dia ram may be present as a
visual aid. Most panels are subdivided into boxes with each box controllin exactly one host interface messa e. In most cases the
attributes are presented in the same order (as read from top to bottom) as that in which they appear in the Host Interface
Messa e. Thus for the most part the remainder of this document is simply a rehashin of the descriptions already available in the
Host Interface Document.
Force link rediscovery de-re isters a Lo ical Link, while allowin it to re-re ister, as if it had been newly attached to the EPON
network. This command is useful, for example, when the Network operator wants to be able to force a re-arrival as part of their
debu in process to try to clear a problem, or to re-authenticate the user/ONU on that link.
The Block Link command prevents the iven Lo ical Link (MAC address) from re isterin on the EPON. The OLT will simply i nore
re istration requests from the blocked ONU. If the iven ONU is already re istered, the Lo ical Link will be dere istered, causin
the ONU to depart from the network. All further requests to re ister from the ONU are i nored until the Host issues an Unblock
Link command.
Up to 256 ONU labels (MAC addresses) can be on the block list at one time.
Link blockin is intended to be a temporary measure used to suspend service for reasons such as late payments or a troublesome
customer. When the issue has been resolved, or the ONU has been physically removed from the network and no lon er requests
service, it can be removed from the blocked list with the Unblock Link command. If the ONU is still connected to the network and
attemptin to re ister, the ONU will be once a ain allowed onto the network.
Service provisionin such as SLAs or Brid in modes are not affected by the Block Link command. Any ONU provisionin should be
deleted with the appropriate other commands, if desired. A blocked link will appear with a black status icon.
Please note the difference in the behavior with respect to the Block Link command where an Unblock Link is required to undo its
effect. Link Rediscovery invites the ONU to re-re ister this link with the network, while Block Link prevents the ONU from
returnin on that link after dere istration.

5 OLT Panel
The OLT panel is used to apply settin s to OLT attributes. In some cases this may also involve OAM
transactions with ONUs. It should be noted that certain attributes of the OLT such as SLAs are controlled
via the Link Panel.
6 OLT Netw rk Parameters These commands allow the host to confi ure the way the PON will be mana ed.
6.1 OAM Rate
This command is used to view the default OAM rate
6.2 L pback Time ut Value
This sets the loopback failsafe timer. If the operator sets a port in loopback mode the loopback the OLT will initiate a count down
timer for Loopback Timeout Value ms. When the timer expires the loopback will automatically be canceled.
6.3 MPCP Parameters
6.3.1 Peri d
The interval at which the OLT will issue a discovery ate.
6.3.2 Wind w
The discovery window size in bytes.
6.3.3 VLAN Ethertype
This is the Ethertype value that the OLT will use to classify VLAN traffic (default = 0x8100)
7 DBA
The DBA tab allows the user to control virtually every parameter of the TK3721’s hi hly flexible and efficient Hierarchal Wei hted
Round Robin DBA al orithm. The DBA al orithm supplied with the OLT is similar to al orithms found in hi h performance ATM switches
and is capable of issuin 4 rants every 282 micro seconds, by far the fastest cycle time of any EPON system deployed today. The
TK3721’s DBA can meet 1 ms. Latency requirements for hi h priority services in a 32 ONU deployment.
7.1 Br adcast SLA

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
This command is identical to the functionality of the Link SLA Panel except that it is used to provision an SLA for the broadcast channel,
as apposed to a unicast link. This unique feature of the OLT allows the OLT To use its lar e 40Me buffer ram to serve the requirements
of all ONUs, resultin in a 1:32 cost reduction (assumin 32 ONU deployment).
7.2 Aggregate Shaper
This command lets the Host restrict the bandwidth available to the OLT for user data traffic in each direction. This feature can be used
to protect the core network from bursty upstream flows and increase the accuracy of SLA enforcement. A re ate bandwidth control
can be disabled by settin the parameters to zero; the feature is disabled by default.
For accurate Min SLA enforcement. recommends that the upstream a re ate shaper be provisioned for 50-100Mbps less than the
maximum bandwidth of the PON. Typical values are 800-850Mbps.
7.3 Pri rity Range

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
The priority ran e determines how many links may be re istered in each priority level. This command should be applied immediately
before re isterin any links, or after links are dere istered usin the Disable OLT command. It is a ood idea to confi ure the OLT in
strict boot mode, allowin the host software time to apply this command and then explicitly enable the OLT to re ister links.
The OLT must be disabled prior to applyin this command; otherwise the OLT FIFOs will become corrupt. It is recommend that this
operation be performed once durin the initial brin up of the PON.
7.4 Shaper Dr p D wn Weights
This command is not available for the TK3721, and applies to future chipsets only. The TK3721 has a strict priority FIFO scheduler.
7.5 DBA Dr p D wn Weights
DBA drop down wei hts are used by the DBA to reserve bandwidth for each priority level. This allows the OLT to fix the latency and
reserve a percenta e of bandwidth for links in each priority level.
The drop down wei ht for priority level n MUST be reater than or equal to the provisioned DBA Wei ht for all links in priority level n +

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
1.
7.6 P lling Rates
The pollin rates panel allows the operator to confi ure the rate at which each link will be solicited to determine if it has any data to
transmit. Smaller values result in lower latency and increased overhead. For priority 0, the schedulin latency is approximately equal to
the lar er of the pollin rate and the cycle len th.
7.7 Service Level Agreement
Every element scheduled by the OLT has an associated SLA record which can be confi ured by the GUI or other host systems.
7.8 Unicast SLA SLA

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
Every Lo ical Link re istered by the TK3721 has an associated SLA maintained by the TK3721, and stored internally in its NVS database
(if enabled to do so). In the upstream direction, the TK3721 uses a reportin mechanism specified by 802.3ah to monitor the status of
each re istered link. When a particular Link’s FIFO(s) has data to send this information will be conveyed to the OLT in the form of a
report messa e. The OLT will use this information and the SLA associated with the link to schedule a time slot in which the link may
transmit its data. Because the OLT schedules the links, rather than relyin on mechanisms in the ONU, service contracts are enforced in
the central office, and excess bandwidth may be allocated efficiently. SLA enforcement is accurate to within 2% of the provisioned
value.
7.8.1 Enable SLA
If checked, the OLT will allow the element to transmit user data.
7.8.2 Max Bw
Confi ures the maximum sustained rate at which a link may transmit data.
7.8.3 Min Bw
Confi ures the sustained rate at which the user may transmit without loss of data, this value should always be less than or equal to Max
Bw.
7.8.4 M de
Determines the scheduler level
From the perspective of the GUI or other external devise mana in the TK3721 “Delete” semantically
equivalent to restore factory default and “Create” is equivalent to chan e the SLA from default value.
7.8.5 Enable SLA
This attribute allows the host to disable SLA’s
It is important to note that thou h the lo ical link panel appears rouped under the ONU, lo ical link attributes are NOT necessarily
attributes of the ONU itself. Lo ical links ALWAYS make two associations one with the ONU and one with the OLT. Unless explicitly
specified, lo ical link parameters may be parameters of the OLT, ONU or both. It is best to assume that ALL operations performed on a
lo ical link involve OAM transactions with the ONU.
Thou h the TK3721 has a Min/Max FIFO scheduler in the upstream direction, the DBA is not directly influenced by the Min scheduler.
Instead it responds to si nals enerated by queue depth. To ensure that the Min’s are scheduled accurately it is necessary to restrict
the total upstream bandwidth of the PON by 50 to 100Mbps. This can be accomplished by provisionin an a re ate SLA.
As per IEEE 802.3ah, any ONU admitted to the network will be ranted a small amount of bandwidth sufficient for minimal OAM
operation, even if the SLA is disabled. A disabled SLA can use up to 256K. As per specification the ONU is not aware of SLA’s, and thus
will continue to transmit user data which will be dropped by the OLT. To prevent the ONU from transmittin this unwanted data it is
recommended that the ONU be confi ured in strict boot mode. In this mode the ONU will ONLY transmit user data after the host
software has explicitly enabled it to do so.
In strict (or host driven) boot mode the SLA will be confi ured in the disabled state every time the link is re istered. In auto-boot mode
the state of the SLA is enabled by default and stored in the OLT NVS if NVS is enabled.
8 P rt Management

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
8.1 OLT P rt Management
Allows the user a simple interface to control port parameters such as line speed and flow control. If Auto Ne otiation is enabled, the
speed and duplex settin s used will be based on the result of ne otiatin with the link partner. Default values depend on the
personality settin s. The table below describes the Set command. In the current firmware release, flow control is not auto ne otiated. If
flow control is enabled the firmware will confi ure the Phy to advertise flow control. Note however that pause frames will be
transmitted re ardless of the capabilities reported by the link partner.
8.1.1 C nfiguring P rt in L p
Allows the user to set a loop back, currently the loop back position must be set to MAC.
8.1.2 Manage Fl w Ctrl Parameters 流控参数管理
流控参数管理流控参数管理
流控参数管理
Sets the flow control on/off threshold values.
For the Flow Ctrl thresholds: the precision of the values is less than the displayed percenta es. So small chan es between the
provisioned and actual value may exist
9 OLT Traffic Management
The traffic mana ement panel allows the user to chan e brid in modes, apply complex filters, and expose many of the OLTs advanced
hardware and software features related to traffic mana ement.
9.1 Bridging C nfigurati n Bridging

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
This panel facilitates provisionin of the brid in mode for each link, as well as the size of the dynamic forwardin table on a per link
basis. If the brid in mode supports VLAN, the VLAN ta or ta s may be specified usin this panel. For certain VLAN modes such as
priority shared VLAN multiple links may be provisioned in the same VLAN. These modes will make forwardin decisions based on
multiple fields such as MAC address and VID.
A link may be provisioned in only one brid in mode. However, multiple links, each provisioned in a different mode, may be associated
with a iven e ress ONU port.
9.1.1 Changing the bridging m de f r a particular l gical link
Notice that after the brid in mode has been applied the Apply button will chan e to a rey color.
Notice that after the VLAN has been provisioned the panel will chan e to a rey color. The user must delete the VLAN provisionin
before applyin a new ta value.
Once a VLAN has been provisioned, the OLT will not permit the brid in mode to be chan ed without first deletin the VLAN
provisionin . If an attempt is made to chan e the brid in mode, the GUI will display a dialo box allowin the user an opportunity to
automatically delete the VLAN provisionin .

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
Clickin “Yes” will delete the VLAN ta and chan e the brid in mode. Clickin “No” will abort the operation.
The exact panel used to apply VLAN provisionin will chan e based on the provisioned VLAN mode.
9.1.2 Pr visi ning a link in a Dedicated VlAN
Dedicated VLAN modes associate a sin le VLAN ta with a particular Lo ical Link. The provisioned priority field (CoS) will be added to
upstream frames. However, only VID is used to make a downstream brid in decision. VLANs are terminated by the TK3721.
Once a value has been entered for VLAN ID and Pri (CoS), the “Set” button may be used to apply the provisionin . The “Clear” button is
used to delete the provisioned ta .
9.1.3 Pr visi ning a link in a Shared Shared VLAN modes associate multiple links with a sin le VLAN. The upstream CoS inserted by the
TK3721 is always 0.
Notice that the panel features a “Set” button similar to the panel used to provision the dedicated VLAN. This button has identical
functionality.
In addition to the VLAN provisionin box, a second box appears to the ri ht that is used to display a list of all lo ical links in the
provisioned VLAN. No links will be displayed in this box until the VLAN provisionin is applied. Clickin on a lo ical link in this list allows
the user to quickly chan e the context of the panel to the other lo ical link. This is useful when chan in links to a different VLAN.
9.1.4 Pr visi ning links in Transparent
Transparent VLAN uses the VLAN ta for downstream brid in decisions but does not modify the ta . A sin le link may be provisioned
with multiple VIDs. It should be noted that the CoS field is not used for brid in decisions. Upstream frames shall be brid ed re ardless
of the Ta value.
The “Add” button is used to add a VID and the “Delete” button is used to remove a VID.
A box to the ri ht of the provisionin window is used to display all of the VIDs associated with a particular lo ical link provisioned in
Transparent VLAN. Selectin a VID in the box moves it into the provisionin window, allowin it to be quickly deleted. Once a VID is
deleted the VLAN field in the provisionin window will take on one of the other provisioned values, allowin all VLANs to be quickly
deleted with repetitive mouse clicks.

9.1.5 Pr visi ning links in a Cr ss C nnect
Cross Connects are used to create a private link between two ONUs on the same PON. For instance, a link Cross Connect mi ht be used
to facilitate data communication between two offices within the same or anization. Both links must be provisioned in the Link Cross
Connect mode before a Link Cross Connect can be established. Once both links have been provisioned in Cross Connect mode, use the
Connect button to brid e the links.
Once cross-connected the control will ray out indicatin that the action was completed successfully.
Only a sin le Cross-Connect may be established with any iven link.
9.1.6 Pr visi ning Pri rity VLANs
Priority VLANs use the ToS or CoS field to make brid in decisions. The decision of which field should be used is based on a per link
attribute, however, in the TK3721 this is a lobal settin . Once one link has been provisioned in a priority VLAN, all links MUST provision
the ToS/CoS select the same way. It should be noted that if L3 switchin is used only ToS may be used for the priority field.
。
9.1.6.1 VID Field
This field allows the user to select the VID. The VID will be inserted into upstream frames arrivin on links provisioned in the VLAN.
Downstream the VID will be used for classification.
9.1.6.2 Upstream C S
The upstream CoS is the CoS value that will be inserted into upstream frames, forwarded on the VLAN. It is VERY important to notice
that a unique upstream CoS and VID combination defines a unique VLAN. For every link provisioned in a unique VLAN, EVERY attribute
in the VLAN record other than the link label, MUST be identical. Identical, means that for link A and link B provisioned in VLAN C a
bitwise comparison of the two records used for provisionin would show equality. If this is not the case the TK3721 will not function
correctly, and NVS erase followed by system reset may be required to restore proper functionality.
9.1.6.3 Max/Min Range
Allows the user to provision an INCLUSIVE ran e of priority values used for downstream classification. Packets with matchin VID and a
CoS/ToS value in the ran e specified will be classified onto the VLAN. It is VERY important that for every VID, there exists VLANs {V 0 ,
V 1 , …,V n } such that to ether they specify a complete ran e [0 7] with no holes. Also note that for any two unique VLANs with VID=A, it is
ille al that the two VLANs Max/Min contain ANY overlappin re ions (e. . [0, 4] and [4, 7] would be ille al).
9.2 Pr visi ning Filtering Rules

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
This panel allows the operator to create rules to filter (drop received frames), based on many different criteria (Rules).
9.2.1 Selecting the P rt f r Filtering
The Port to Filter is selected usin the Port drop down box.
9.2.2 Using the Rule Grid
The Filterin Panel Rule Grid is almost identical to the Classification Panel Rule Grid, except that the Q
column is absent, as it is not required.
9.2.3 C nstructing an OLT Filtering Rule
Step 1. Choose the Field Select. Field Selects defined by the OLT are iven a descriptive label.
Step 2. Choose an appropriate Operator. The operator tests the portion of the frame specified by the field
select.
Step 3. Choose an appropriate Lookup Value. This is the value that will be used by the operator in the comparison. This step is only
applicable to binary operators. If the operator selected is unary (such as Field Exists) the Value field will be disabled.
Step 4. Add the clause to the Rule Editor usin the left arrow button. Note that the ri ht arrow button can
be used to remove a selected clause from the Rule Editor.

Step 5. Repeat steps 1-4 until the desired rule has been created. The TK3711 supports a maximum of 2
clauses / rule. The TK3701 supports a maximum of 8 clauses / rule.
9.2.4 Adding a Filtering Rule
Step 1. Select the Port to Filter.
Step 2. Set the rule precedence level. The Rule Level may be confi ured for 1 of 8 different precedence levels, 0 bein the hi hest
priority and 7 bein the lowest. Currently the precedence level of user provisioned filterin rules is of little importance.
Step 3. Add the filterin rule to the OLT by clickin the Add button.
Addin a filterin rule will cause the OLT to be updated without an additional apply action.
9.2.5 Deleting a Filtering Rule
Once a filterin rules has been added the rule may be deleted by selectin it from the Rule Grid and
clickin the Delete button.
Once the rule has been successfully deleted it will be removed from the Rule Grid.
9.3 L3 Switching

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
The OLT may be confi ured as an L3 brid e, enablin the OLT to learn IPv4 destination addresses. The L3
panel allows the user to confi ure the OLT for L3 switchin . This operation should enerally be performed
prior to applyin any VLAN provisionin . Brid in confi urations that make use of the CoS field are
incompatible with L3 switchin . The primary advanta e of L3 switchin is security. L3 switchin enables
the OLT to direct ARP and RRARP frames based on the learned IP address, makin the network less
susceptible to MAC spoofin attacks.
9.3.1 DHCP Sn ping Enable
This parameter enables the OLT to learn IP frames based on snoopin DHCP offer messa es.
9.3.2 DHCP Opti n 82 (Relay Agent Sub-Opti n…)
If L3 switchin is enabled the OLT may be confi ured as a DHCP relay a ent (RFC 3046.) This will
enable the OLT to insert the Relay A ent Sub-Option into snooped frames.
9.3.3 DHCP IPv4 Address Learning
9.3.3 DHCP IPv4 Enables IPv4 address learnin via DHCP snoopin . Frames shall not be forwarded until L3 address is
learned. ARP frames shall be unicast to appropriate link.
9.3.4 ARP Sn ping (Sn p ARP Frames…)
9.3.4 ARPsnoop
Enables the OLT to classify ARP frames into its processor FIFO. This allows the OLT to redirect the
frames based on learned IPv4 destination address.
9.3.5 ARP Pr xy
This is future functionality and will be described upon completion.
9.3.6 Dyn. IP Learn Table Size
9.3.6 Dyn 。 IP Learn Table Size
Specifies the number of IP addresses that may be learned.
9.3.7 DHCP Relay Agent IP SA
Specifies the IP source address to be used for the relay a ent. This is the address to be used for rAddr ,
inserted into DHCP frames modified by the OLT.

9.3.10 IPv4 Dynamic Filter Table

SNA8110T Gepon OLT User Manual
陈泽科技有限公司 www.stephen-tele.com
The learned IPv4 address table is exposed by the L3 Table tab on the GUI
If any of the checkboxes in the Mode box are checked the L3 switchin shall be enabled.Otherwise L3 switchin is disabled.
If desired, Relay A ent IP SA may be provisioned with the same value as the IGMP Proxy.
All L3 parameters must be selected in-order for the OLT to insert DHCP Option 82 into upstream DHCP frames.
Currently the OLT appends DHCP Option 82 to all L3 frames.
The Relay A ent IP must be an IP on the same subnet as the DHCP server.
If the L3 switchin function is enable the Dyn. IP Learn. Table Size field should be provisioned with a non-zero value.
10 Alarms
The OLT alarms man er works in concert with the ONUs to provide enhanced mana ement capabilities
and complementary set of OLT specific alarms. Features include:
 A common mana ement interface for ONU and OLT alarms
 Soak of alarms on a per alarm ID basis
 Auditin of all alarms known to the OLT
 Settin of alarm thresholds for ONU and OLT alarms
 Autonomous alarm reportin
 Soak of alarms on a per alarm ID basis
10.1 Viewing Alarms
Unlike the ONU CLI the OLT CLI does not offer any ability to control the alarms man er. Fortunately the Evaluation Kit GUI exposes all of
the underlyin functionality.
Observin Alarm Events
Alarm may be observed remotely via the Evaluation Kit GUI, in 4 ways:
The GUI Lo Window will display all autonomous alarm messa es received from the OLT’s 10/100 craft
port. If alarm auditin is enabled the GUI may also be confi ured to display messa es received based on
the audit.
The appropriate Status Icon will chan e to a yellow trian le indicatin that an alarm is raised.
The Active Alarms panel associated with the alarmed entity will indicate the exact alarm that has been
received from the host interface. This record will be maintained until an event causes the alarm to clear.
