Bridging I.D.

When using line cards introduced prior to the “AA” series, SNA/DLC/NetBIOS traffic may not be

properly bridged across the X-Pedition. The issue in bridging DLC packets occurs where the length

field within an IEEE 802.3 frame indicates less than 46 bytes of data.

The X-Pedition removes the length field information of incoming IEEE 802.3, 802.2, and Ethernet

SNAP packets and recalculates the field prior to retransmission. Consequently, this calculation is

based on the entire length of the data field. A packet entering the X-Pedition with a length field

indicating a data field of less than 46 bytes will exit with the length field recalculated incorrectly. This

can be a problem with LLC2 and legacy IPX applications. Typically, such packets exist only in SNA

and NetBIOS/NetBEUI environments.

Hardware

Limitation

Cabletron Discovery Protocol (CDP) I.D.

Cabletron Discovery Protocol will not function on a SmartTRUNK if enabled with the following

command:

cdp set port-status enable port <port-list>

This command will be rejected.

Workaround: Enable CDP with the all ports parameter, rather than the <port-list> parameter. This

should allow CDP to function properly on a SmartTRUNK.

F1011

CDP identifies some adjacent device types (such as switches, routers, etc.) incorrectly. F1324

CDP packets are not being checked for authentication code length. This length should be 16 (in

decimal); if the value, when checked, is not within this parameter, the packet should be dropped and

the invalid authentication code counter incremented.

F1340

CDP does not correctly identify local ports which are a part of a SmartTRUNK. F1350

If the CDP transmit frequency is altered from its default setting the hold time will not change. Hold

time should always equal 3x the increment between transmits.

CDP hold time will function normally at the default transmit frequency setting.

F1401

Control Module (CM) I.D.

In a dual Control Module configuration, only the Primary Control Module’s Boot Firmware can be

updated.

F0535

Dynamic Host Configuration Protocol (DHCP) I.D.

The dhcp <scope_name> set ping-timeout <number> command is not currently supported. F1680

The Enable mode command dhcp show displays incorrect information if the DHCP configuration is

negated before lease expiration.

F1682

Distance Vector Multicast Routing Protocol (DVMRP) I.D.

If T-series line cards are not in use, a multicast packet can be replicated to only one IP VLAN in an

802.1Q trunk port. Additionally, access-routed interfaces should be used when routing multicast

packets between two DVMRP routers.

Hardware

Limitation

Fiber Distributed Data Interface (FDDI) I.D.

Changing the station mode on a FDDI port will negate all previously executed FDDI commands. F1266
