Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

Workaround: There is no workaround.

• CSCso76863

Symptoms: With a Cisco 7600 series router, occasionally the RP may crash when a SIP or SPA is

reset.

Conditions: The symptom is observed when an RP is very busy when a SIP or SPA is reset. For

example, the crash has been seen intermittently when an ESM or SPA card was reset while a large

number of BGP routes are toggling.

Workaround: There is no workaround.

• CSCso77116

Symptoms: End to end connectivity is broken when pseudowire is configured on a port-channel

interface or sub-interface and the member links are on LAN ports

Conditions: xconnect has to be configured on the port-channel interface or sub-interface.

Workaround: There is no workaround.

• CSCso78716

Symptoms: SNMP object entPhysicalVendorType returns incorrect value.

Conditions: Occurs only on a Cisco 7603s.

Workaround: There is no workaround.

• CSCso79720

Symptoms: When the show interface command is entered, all of the Layer 2 switch port interfaces

on ES-20 are shown with the same bridge MAC.

Conditions: Only seen on ES-20.

Workaround: As a workaround, the interface when configured to switchport, then the mac-address

for the same can be correctly set by following procedure:

a.) Execute the command show idprom module <module> details.

b.) lookout for the field ’mac base’ and ’mac_len’ field in the output.

c.) Assign ’mac base + port_num’ as the mac-address to the port on ES20. (Ensure that ’mac base +

port_num’ lie within the range of ’mac base + mac_len’

Further Problem Description: Ideally, when a port is configured as a switchport, it’s desired that

each port should have a unique mac-address. However, it was not like this rather all the ports were

having same mac-address. which is not correct if the port is put in switchport mode. However, if all

those ports which are ’not switchports’ and are routed ports, they’ll share the same-mac-address. It’s

as per the design.

• CSCso80159

Symptoms: IP Subscriber session ingress traffic is routed into incorrect VRF.

Conditions: Occurs when the first access interface is up on a non-default VRF.

Workaround: There is no workaround.

• CSCso80545

Symptoms: If an interface changes from a down to an up state, and a better native path is available

for multicast traffic, the RIB may still use the old path for multicast.

Conditions: The symptom is observed when the mpls traffic-eng multicast-intact command is

enabled under router isis tag. In addition, the route to the source has to be learnt over the TE tunnel.
