AutoCross jumper (J6)
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X) cables to be used when
connecting to 10Base-T, 100Base-TX, or 1000Base-T devices, such as hubs, transceivers, or network
interface cards (NICs). AutoCross determines the characteristics of the cable connection and
automatically configures the units to link up regardless of the cable configuration.
The AutoCross 3-pin header (J6) is located on the circuit board of the C3210 (labeled NA = No Autocross
and A= AutoCross). See the Jumper positions below.
Note: Use small needle-nose pliers to set the jumper.
A Either straight-through or crossover cable can be used for all
twisted-pair copper links.
NA Straight-through or crossover twisted-pair cable, depending on
installed site devices, MUST be installed at EACH twisted-pair
copper link.
Note: The factory default is “A” (AutoCross enabled). Lantronix recommends leaving the device in the “A”
(enabled) position.

Operation
Status LEDs
Use the status LEDs to monitor C3210 operation in the network.
Power and fiber status LEDs
The status LEDs for the 1000Base-X fiber connection (labeled LACT and PWR) are
located next to the fiber port (Port 2).
PWR: Power ON = Connection to chassis power.
LACT: Link activity ON = A link has been established for the fiber connection.
Flashing = The fiber connection is transmit.
Copper port status LEDs
The status LEDs for the copper connection are integrated into the RJ-45 port. These LEDs are not
labeled on the C3210 . See drawing below.
Duplex/Link:
Orange A link in half-duplex mode has been established for the

Product features
Auto-Negotiation
The Auto-Negotiation feature allows the C3210 to configure itself to achieve the best possible mode of
operation over a link, automatically. The C3210 broadcasts its speed (10 Mbps, 100 Mbps, or 1000 Mbps)
and duplex capabilities (full or half) to the other devices and negotiates the best mode of operation.
Auto-Negotiation allows quick and easy installation because the optimal link is established automatically.
No user intervention is required to determine the best mode of operation.
A scenario where the C3210 is linked to a non-negotiating device, the user may want to disable Auto-
Negotiation. In this instance, the mode of operation will drop to the least common denominator between
the two devices (e.g., 100 Mbps, half duplex). Disabling this feature gives the user the ability to force the
connection to the best mode of operation.
Note: The C3210 supports 1000 Mbps fiber Auto-Negotiation.
Link Pass-Through
The Link Pass-Through feature allows the C3210 to monitor both the fiber and copper RX (receive) ports
for loss of signal. In the event of a loss of an RX signal (1), the C3210 will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end device is automatically notified
of the link loss (4), which prevents the loss of valuable data unknowingly transmitted over an invalid link.
Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type of cables that are used.
See pages 1 and 2 for the cable specifications for the different C3210 models. The 512-Bit Rule does not
apply in a full-duplex network.
Half-Duplex network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the round trip delay limitations of
each Fast Ethernet collision domain. (A collision domain is the longest path between any two terminal
devices, e.g. a terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating the round-trip delay in
bit-times (BT) of a particular collision domain. If the result is less than or equal to 512 BT, the path is
good.

Lantronix C3210 Install Guide
33414 Rev. D https://www.lantronix.com/ Page 11 of 20
Pause
The pause feature is used to suspend data transmission temporarily in order to relieve buffer congestion.
If a C3210 needs some additional time to clear network congestion, it will send a pause signal to the
C3210 at the other end, that C3210 will wait a predetermined amount of time before re-transmitting data.
This feature reduces data bottlenecks, allowing for more efficient use of the network devices while
preventing the loss of valuable data.
In Software mode, the pause feature can be set to one of four settings:
•Disable (i.e., no pause)
•Symmetrical pause
•Asymmetric TX (transmit) pause
Note: Enable the pause feature if it is present on ALL network devices attached to the C3210(s),
otherwise, disable the pause feature.
AutoCross
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X) cables to be used when
connecting to devices such as hubs, transceivers, or network interface cards (NICs). AutoCross
determines the characteristics of the cable connection and automatically configures the unit to link up,
regardless of the cable configuration.
Automatic link restoration
The converter will automatically restore the link between networked devices after a fault condition has
been corrected. In contrast, products from competitors require the user to power down, then power up the
converters after a fault condition has been corrected.
Bandwidth allocation
It allows setting the bandwidth in varied increments, starting at 64 Kbps to full bandwidth. Rate limiting
based on frame priorities can also be configured. Each higher priority frame can be configured to get
twice the bandwidth of lower priority frames (e.g., priority “3” frame configurations can get twice the
bandwidth of priority “2” frames).
Port-Based VLAN
Allows secure traffic forwarding in one direction only.

•VLAN Forwarding Rules
•Priority Forwarding Rules
•VLAN Tag Management
•User Priority
•RMON Counters
•Port Counters Received
•Port Counters Sent
•Dot3 Statistics
Port 2 (Same as Port 1 plus the following):
•DMI Statistics
RMON counter on each port
RMON statistics such as packet size counters, collision errors, and packet type are kept for each port.
Switch selectable speed
On UTP (unshielded twisted pair) when Auto-Negotiation is disabled the speed can be sent in either
software or hardware mode.
Virtual cable test (VCT) on UTP port
The VCT feature utilizes Time Domain Reflectometry (TDR) technology to remotely and non-evasively
diagnose the quality and characteristics of the attached cable plant. Using this technology, the devices
detect and report potential cabling issues such as cable opens, cable shorts or any impedance mismatch
in the cable and accurately report (within one meter) the distance of the fault. In addition, VCT technology
will detect pair swaps, pair polarity reversal, and an excessive pair skew.

IEEE802.1q VLAN tagging and double tagging (Q in Q)
The 802.1q specification establishes a standard method for inserting virtual LAN (VLAN) membership
information called a tag into Ethernet frames to break large networks into smaller parts, or to address
security concerns. Q in Q support simply adds another layer of IEEE 802.1q tag to the 802.1q tagged
packets that enter the network. The purpose is to expand the VLAN space by tagging the tagged packets,
thus producing a "double-tagged" frame.
VLAN tagging can be configured to one of the following settings:
•Customer (Normal) = frames are unmodified when passing through the converter.
•Network (Untag) = all tagged frames will have their tags removed when passing through
converter.
•Network (Tag) = all untagged frames are tagged with the source port default VLAN ID.
•Provider (Double Tag) = all egress frames are double tagged, using the source port default
VLAN ID for the extra tag. This also enables ingress double tag removal.
Ingress:
a. Frame does not contain a tag, frame is not modified.
b. Frame contains one 802.3ac tag, tag is removed.
c. Frame contains two 802.3ac tags, the first tag is removed.
Egress:
a. Frame is untagged, tag is added.
b. Frame contains one 802.3ac tag, tag is added before the current one becomes the frames new
802.3ac tag.
IEEE802.1p QoS, IPv4 ToS/Diffserv, IPv6 Traffic class
The 802.1p specification is an extension of the IEEE 802.1q standard and works in tandem to define the
prioritization of the Ethernet frame for traffic class expediting and dynamic multicast filtering. IEEE 802.1p
establishes eight levels of priority (0 ~7) with “7” being the highest priority. Each egress Ethernet frame
can be prioritized using IEEE 802.1p (MAC level) Traffic Class, or IPV4 TOS and/or DiffServ and/or
IPV6 Traffic Class.
