Interfaces and Bridging
• CSCed75174
Symptoms: A router may not forward VLAN traffic.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(28)S
when there are no features configured under VLAN.
Workaround: There is no workaround. The symptom does not occur in Release 12.0(25)S1.
• CSCee47714
Symptoms: Entering the shutdown command on a controller of a Packet over T1/E1 Network
Transceiver puts the controller permanently down. Entering the no shutdown command on the
controller does not bring the controller up.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0 S
and is specific to the controller that is installed in a PA-MC-8T1/E1, PA-MC-4T1/E1, or
PA-MC-2T1/E1 port adapter.
Workaround: There is no workaround.
• CSCee58873
Symptoms: The show controllers t1 slot/port command may show only the current interval.
Conditions: This symptom is observed on a Cisco 7200 series when FDL is configured.
Workaround: There is no workaround.
Further Problem Description: When FDL is configured, the router updates the MIB data after
checking for a valid local and remote MIB data interval that it receives from the T1 port adapter.
During the remote MIB update, and if the received data interval is invalid, the router clears both the
remote and the local data instead of clearing only the remote data and starting again.

Conditions: This symptom occurs on an ATM interface that flaps when there is a service policy
attached to an ATM permanent virtual circuit (PVC) that has Multilink PPP (MLP) and link
fragmentation and interleaving (LFI) enabled.
Workaround: There is no workaround.
• CSCin66616
Symptoms: The output of an snmpwalk for the entPhysicalDescr MIB on a PA-MC-8E1/120 may
shows the PA-MC-8E1/120 as unknown.
Conditions: This symptom is observed on a Cisco 7500 series in which a PA-MC-8E1/120 in
installed.
