Symptoms: VIP containing PA-1FE (FastEthernet) may crash when the router is reloaded or on an
MTU change in any of the interfaces of a Cisco 7500 router.
MTU change in any of the interfaces of a Cisco 7500 router.
Conditions: This symptom has been observed when a Cisco 7500 with one port FastEthernet PA is
reloaded and the VIP slot becomes wedged.
reloaded and the VIP slot becomes wedged.
Workaround: Doing a soft Online Insertion and Removal (OIR) would return the wedged VIP with
1 port FE PA to normal operation.

Symptoms: POS interfaces may remain in the up/down state after the router has been reloaded.
Conditions: This symptom is observed on a Cisco Catalyst 6500 series, Cisco 7500 series, and Cisco
7600 series.
7600 series.
Workaround: Reload the FlexWAN or VIP in which the POS port adapter is installed.

Symptoms: Layer-1 alarm handling does not meet the ANSI T1.231 standard on a PA-A3-T3
interface. The PA-A3-T3 port adapter does not provide a soaking time to declare and clear near-end
failures such as LOS, LOF, and AIS. Also, PA-A3-T3 interfaces do not properly handle P-bit and
C-bit errors and do not bring down the controller when the threshold is reached for such errors.

Symptoms: An Ethernet interface may accept packets for any destination MAC address. The router
will process them and will forward them through the appropriate interface should a valid entry exists
in the routing table.
will process them and will forward them through the appropriate interface should a valid entry exists
in the routing table.
Conditions: The controller is in promiscuous mode and bridging is configured in any interface in the
router. The output of show interface interface irb for the affected Ethernet interface prints the
following message for all subinterfaces:
router. The output of show interface interface irb for the affected Ethernet interface prints the
following message for all subinterfaces:
Not bridging this sub-interface.
Workaround: In the affected Ethernet interface: 1. Configure a subinterface with a dumb VLAN. 2.
Configure bridging in that subinterface. 3. Remove the bridging configuration. 4. Remove the
subinterface.

Symptoms: ISDN L2TP sessions cannot be brought up.
Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS Release 12.4 or
Release 12.4T and that is configured with a PA-MC-8TE1+ port adapter that functions in T1 mode.
The symptom is platform-independent and could also occur in Release 12.3.
