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 port-channel has members from both bays and
EVCs are removed and then added.
Workaround: Conduct a line card OIR.
• CSCso91230
Symptoms: A router may display the following error:
%LINK-2-INTVULN: In critical region with interrupt level=0, intfc=ATM0 -Process= "IGMP
Snooping Receiving Process"
Conditions: The symptom is observed when bridged traffic is passing to an MLPP interface.
Workaround: Disable IGMP snooping with the no ip igmp snooping command.
• CSCso92175
Symptoms: The configured value of a queue-limit gets changed and locked at 16000 bytes when
random-detect is applied to the policy-map and service policy is attached to the interface.
Conditions: The symptom is observed when a queue-limit is configured in front of the WRED in the
same class of policy-map.
Workaround: Configure the WRED in front of queue-limit in the same class of policy-map.
• CSCso92930
Symptoms: Available memory may decrease over time on a Cisco ASR1000 RP as subscribers
connect and disconnect.
Conditions: This symptom is observed when the Cisco ASR1000 functions as a LAC or LNS. AAA
accounting is enabled for tunnel, session and PPP.
Workaround: If the available memory decrease impacts system functions, disable AAA accounting
as a temporary remedy.
• CSCso93065
Symptoms: Standby RP crashes while receiving dynamic sync from active RP during DHCP relay
binding creation.
Conditions: Occurs when outer is configured as DHCP relay and running IOS images that include
the fix for CSCsm86039.
Workaround: There is no workaround.
• CSCso93883
Symptoms: Upon reload of a DFC, traffic coming from the MPLS cloud might be dropped when the
traffic is destined for a EoMPLS connection on a MUX-UNI
Conditions: This is seen on 12.2(33)SRB3 and 12.2(33)SRA3. The incoming module needs to be a
DFC, and the egressing port needs to be a MUX-UNI. This does not happen to regular Ethernet Over
MPLS (EoMPLS) connections.
Workaround: Perform a shut/no shut on the connection towards the MPLS network, then shut/no
shut the VC.
• CSCso93959
Symptoms: Newer SDRAM devices on the 2- and 4-port OC48 POS/RPR SPA require an additional
initialization sequence as recommended by the vendor. Without this new initialization sequence,
packets that go through the transit buffer in RPR/SRP mode or in subscription mode may get
corrupted, or packet loss may occur.
Conditions: Card initialization after inserting the SPA or removing an unpowered shutdown.
Workaround: Perform an OIR on the SPA.
