Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The symptom is observed when the internal VLAN ID for the outgoing interface
changes upon the shutdown and no shutdown command sequence.
Workaround: Use the clear ipv6 pim topology group command.
• CSCsq28584
Symptoms: A router may crash from memory corruption.
Conditions: The symptom is observed when a QOS policy is added to the service template in the
BroadHop. It may also be observed if service with TC and L4Redirect action is installed on a
subscriber profile.
Workaround: There is no workaround.
• CSCsq28896
Symptoms: There may be an 100 percent packet loss between hosts connected through a Cisco 7600
series router via frame-relay on different bridge groups.
Conditions: We are still investigating the conditions for this issue. However, we estimate the
following conditions: 1. Seen on Cisco IOS Release 12.2(33)SRA5-7 and Release 12.2(33)SRB3. 2.
When a Cisco 7600 series router is switching traffic between bridge- domains. 3. When both ingress
and egress interfaces are on the same line card and share the same LTL.
Workaround: Use Cisco IOS Release 12.2(33)SRA4.
Alternate Workaround: Force the traffic to be switched in software, either by disabling MLS
switching, or having an ingress access-list specifying the ’log’ statement. Please be cautious doing
this as both workarounds may significantly impact CPU.
• CSCsq29052
Symptoms: Packets are not forwarded out from a point-to-point (P2P) interface.
Conditions: The symptom is observed with CEF enabled and when the P2P interface is changed
from an "ip unnumbered" configuration to another interface.
Workaround: There is no workaround.
• CSCsq29893
Symptoms: Traffic may not flow on a port channel EVC after an OIR.
Conditions: The symptom is observed when a port channel EVC is created with encapsulation
untagged and then an OIR is performed on the linecard.
Workaround: Reapply the configuration on the specific interface.
• CSCsq30401
Symptoms: After a switchover, multilink bundles may fail to come up.
Conditions: This symptom is observed on platforms that support High Availability (HA) such as a
Cisco 7600 series or 10000 series router, and is triggered by an error in synchronizing the state of
the multilink bundle to the standby processor.
Workaround: The only workaround, short of reloading the processor, is to remove the multilink
interface from the configuration with the no multilink interface command and then adding it back.
• CSCsq30717
Symptoms: A NPE-G1 resets due to a hardware watchdog timeout. This is indicated in the show
version output with "Last reset from watchdog reset".
Conditions: The Cisco 7200 must have an enabled PA-MC-2T3-EC with channelized T1s.
Workaround: Disable the PA-MC-2T3-EC.
