Interfaces and Bridging
• CSCdk48089
Removing an ATM Deluxe card from a Cisco 7200 series router and inserting an ATM Lite card in
the same slot may cause the router to fail. There is no workaround.
• CSCdr47324
With fast switching (Optimum, Cisco Express Forwarding (CEF), or flow) enabled, a
Cisco 7200 series router may fail to route packets larger than 1496 bytes from any Fast Ethernet
(FE) interface and a Bridge Group Virtual Interface (BVI). It is also possible that the first packet
may reach its destination (because it is process-switched), but all subsequent packets will fail.
Workaround: Disable fast switching on the FE interface.
• CSCdr57358
An Inter-Switch Link (ISL) trunk does not work between a Cisco Catalyst 5500 and a
Cisco 7000 series router that is running Cisco IOS Release 12.0.7, 12.0.8, or 12.0.11 with a
PA-FE-TX port adapter that performs ISL in software microcode. This port adapter appears in the
output of the show diag privileged EXEC command as 100BASE-TX-nISL. The ISL trunk works
on the PA-FE-TX port adapter that appears in the output of the show diag privileged EXEC
command as 100BASE-TX-ISL and supports ISL in hardware.
Workaround: Create an 802.1Q trunk.
• CSCds14572
With an ATM Lite Port Adapter (PA), permanent virtual circuit (PVC) discovery fails to come up
with the right PVC parameters for variable bit rate-non real-time (VBR-NRT) service category.
This problem happens only for the ATM lite interface. There is no workaround.
• CSCds14583
A six-port CX-Ethernet Interface Processor (EIP) reloads randomly. Ports are shut down and you
must enter the no shut command to bring them back. The following traceback errors are generated
in the log:
