Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCsk25046
Symptoms: For a policy applied to an interface with an ifindex of 14, the corresponding entry will
not appear in cbQosServicePolicyTable. This is impacting device monitoring.
Conditions: The following two conditions are required for the issue to exist:
- There should be an interface with an ifindex of 14 with a policy applied. - There should a be a
policy applied on the control plane.
Workaround: Remove the policy on the control plane.
• CSCsk25838
Symptoms: When congestion control is enabled, some CMs may get sent out of order. The actual
send window size may be smaller than what is allowed by congestion control algorithm, and yet
when the send window size reduces it is treated as if its size did not change.
Conditions: The symptoms are observed at any time when congestion control is not disabled and the
congestion window changes its size due to a change in network latency or processing rate.
Workaround: There is no workaround other than disabling congestion control.
• CSCsk26165
Symptoms: A router may crash because of a bus error.
Conditions: The router must be configured for L2TP.
Workaround: There is no workaround.
• CSCsk28361
Symptoms: 4000 virtual-template (VT) takes high CPU during system load configuration.
Conditions: Occurs when 4000 VT interfaces are loaded from TFTP to running configuration.
Workaround: There is no workaround.
• CSCsk32095
Symptoms: The Ethernet interface flaps after configuring QoS on the interface.
Conditions: Occurs on PA-2FE-TX port adapter after applying QoS to the interface.
Workaround: There is no workaround.
• CSCsk33724
Symptoms: Starting with Cisco IOS Release 12.2(33)SXH, DOM feature is not supported on some
transceiver types. The list of supported transceiver types can be obtained from a running switch
using the command show interface transceiver supported-list. This change has been made to
handle cases where the DOM thresholds or operating values are inaccurate, thereby resulting in
bogus SNMP trap notifications.
Conditions: This issue is seen only with the following conditions:
1. Cisco IOS Release 12.2(33)SXH and later releases.
2. Transceivers listed as "unsupported" in output of show interface transceiver supported- list
command.
Workaround: There is no workaround.
• CSCsk38024
Symptoms: Etherchannel sync issues may be seen on the standby router. Some of the port-channel
member ports might come up on the standby in an "unbundled" state, while on active they are in a
bundled state.
