Appendix
9A426-01/9A426-02
Module Specific Information
Introduction
This appendix contains local management information that is specific to the
following ATM Modules:
• 9A426-01 (1 active front panel port; 1 stand-by front panel port)
• 9A426-02 (2 active front panel ports)
Local Management Screens
The screens shown in this appendix are for the 9A426-02 ATM Module. The
screens for the 9A426-01 ATM Module differ in that there is no Port # field, since
the 9A426-01 ATM Module has only one active front panel port.

Modifying Fields and User Privileges
To modify fields on these modules, you must have read-write or super-user
privileges. If you have read-only privileges, you can view information; however,
you cannot modify any fields.
Virtual Channels andVirtual Paths
Rather than addressing cells to a specific destination, as in a LAN, ATM addresses
cells to Virtual Channels (VCs) and/or Virtual Paths (VPs). This addressing takes
place in the header field of the ATM cell.
VCs and VPs are bi-directional (i.e., they transfer information in both directions
on a single channel or path) and are “set up” between devices on the ATM
network prior to transmission. Similar to WAN transmission, ATM technology
provides the ability of sending several VCs together over a VP, and several VPs
over an ATM link segment.
Permanent and SwitchedVirtual Channels
ATM networks use two different types of Virtual Channels:
• Permanent Virtual Channels (PVCs)
• Switched Virtual Channels (SVCs).
The difference between PVCs and SVCs exists in the channel setup.
PVCs are pre-configured by an administration function, and are usually
established for long-term use. After setting up this channel, nothing else is
required by the network to transfer information between the two established
points. This type of virtual channelling is established through a local or remote
management interface.
SVCs use a signaling and network switching procedure to set up dynamically. In
other words, SVCs are established “on the fly,” as needed for a particular service,
used to transmit on the short term, and then terminated.

ConnectionTable Screen Fields
The following information briefly explains each Connection Table Screen field.
ATM Port Current Connections
Number of virtual circuits that are currently open for this port.
ELAN:
Name of the ELAN to which this client is joined.
VPI
Displays the Virtual Path Identifier number of the listed PVC or SVC.

Displays the Virtual Channel Identifier number of the listed PVC or SVC.
EncapsulationType
Displays the method used to encapsulate data at the ATM Adaptation Layer 5
(AAL5) for each connection. The 9A426-01 and 9A426-02 ATM Modules support
the following methods of encapsulation:
• VC Mux 802.3 LANE ( default )
VC Based Multiplexed 802.3 LAN Emulation. This is the encapsulation type
used when the connection is set up via SVCs. These happen automatically in
the network with no user intervention.
• VC Mux Bridged 802.3
VC Based Multiplexing for bridged protocols. You can choose this
encapsulation type for PVCs to do bridging.
For more detailed information about this field, see the description for the ELAN
Name: field on page 13.

• LLC Encapsulation
Logical Link Control for Bridged Protocols. You can choose this encapsulation
type for PVCs. You cannot use this encapsulation type for SVCs.
LLC Encapsulation inserts an LLC SNAP header for each legacy LAN
network type that is being encapsulated onto ATM. LLC Encapsulation is
desirable when it is not feasible for a larger number of VCs to be supported,
due to ATM device capacity limitations or other outside factors.
• Other
This encapsulation type is for reserved connections that are defaults built into
most (if not all) ATM LANE 1.0 compliant devices. In other words, they are
neither configured by hand nor set up dynamically.
AALType
Displays the type of ATM adaptation layer (AAL) used on this VCC. The AAL
divides the user information into segments suitable for packaging into series of
ATM cells. The AAL types are:
• AAL3/4
• AAL5 ( default )
ELAN: (Modifiable)
Selects the ELAN for which connections are to be displayed.
To select another ELAN, use the arrow keys to highlight the ELAN : field (bottom
left corner of the screen), then press the Space Bar .
PORT #: (Toggle)
Selects a specific ATM port.
To select another port (if applicable), use the arrow keys to highlight the PORT # :
field (bottom left corner of the screen), then press the Space Bar .
Displaying the Add/Delete Entry Screen

LEC Administration Screen Fields
The following information briefly explains each LEC Administration Screen field.
Configure LEC (Toggle)
Specifies whether the LAN Emulation Client should auto-configure the next time
it is started. Use the Space Bar to select one of the following choices:
• Automatic (default) - A client uses a LAN Emulation Configuration Server
(LECS) to learn the ATM address of its LAN Emulation Server and to obtain
other parameters.
• Manually - Management tells the client the ATM address of its LAN Emulation
Server (LES) and the values of other parameters.
ELAN Name
The name of the ELAN to which this client is joined.
By default, the unit makes a LANE join request to the ATM network with the
ELAN name blank (no entry). By popular LANE convention, Join Requests of this
type will put that client into the first configured ELAN on the LECS (also known
as the “default ELAN”). Assume this ELAN is named “ELAN1”. Once the device
has successfully completed the Join process, all ATM-specific Local Management
screens will then reflect “ELAN: ELAN1”. This means that all Local Management
screen information pertains to the “ELAN1” ELAN.
To set the device back to join the “default” ELAN, you must delete the current
ELAN (ELAN1). After the current ELAN is deleted, a message is displayed that
states that there are no longer any active ELANs. Now, you can move to the
ELAN Name: field. Press the Space Bar, then the Return key. Highlight SAVE and
press the Return key. This will cause the device to join the “default ELAN” again.
Since we support just a single ELAN, you cannot create a new ELAN unless all
current ELANs have been deleted.
If you set Configure LEC to Automatic, do not write to any other attribute on the
LEC Administration screen.
NOTE
Future releases will support multiple ELANs. Check your release notes to
determine whether your release supports multiple ELANs.
NOTE

If there are currently no active ELANs, then all choices on the ATM Specific
Configuration Screen will result in the message “No ACTIVE ELAN present”. You
can only access the Connection Table screen and the LEC Administration screen.
You cannot access the LEC Properties screen, since there is no information.
Max MTU Size (Toggle)
The maximum data frame size that this client will use the next time it returns to
the Initial State. Use the Space Bar to select one of the following choices:
• 1516 (default)
• 4544
LANType (Toggle)
The data frame format this LEC is using currently. Use the Space Bar to select one
of the following choices:
• 802.3 (default)
• 802.5
LES ATM Address
The LES this client will use the next time it is started in manual configuration
mode.
ELAN: (Modifiable)
Selects the ELAN for which attributes are to be displayed.
To select another ELAN, use the arrow keys to highlight the ELAN: field (bottom
left corner of the screen), then press the Space Bar.
PORT #: (Toggle)
Selects a specific ATM port.
To select another port (if applicable), use the arrow keys to highlight the PORT #:
field (bottom left corner of the screen), then press the Space Bar.
Adding an ELAN
To add an ELAN:
1. Use the arrow keys to highlight CREATE, then press the Return key.
2. Use the arrow keys to move to the ELAN Name field.
Remember, while we support just a single ELAN, you cannot create a new ELAN
unless all current ELANs have been deleted.

To delete an ELAN:
1. Use the arrow keys to highlight DELETE, then press the Return key.
The message “PRESS SAVE TO CONFIRM DELETE” is displayed.
2. Use the arrow keys to highlight SAVE, then press the Return key.
The message “SAVED OK” is displayed. The ELAN Name field will be updated
after you exit the LEC Administration Screen.
Modifying an ELAN
To modify an ELAN:
1. Use the arrow keys to highlight MODIFY, then press the Return key.
2. Use the arrow keys to move to the field you want to modify.
