Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: After online insertion and removal (OIR) of the SPA or line card holding the active
Automatic Protection Switching (APS) interface, there are two active interfaces for the same APS
group. During OIR, the old inactive interface becomes active and the OIRed interface also comes
back up as active. The OIR interface should come up as inactive.
Conditions: The problem is seen only on ATM SPAs and is seen with both SR-APS and MR-APS
configurations.
Workaround: In the case of a manual OIR, this can be prevented by entering the force APS
switchover command before performing an OIR on the active.
When OIR happens due to other reasons and the problem is seen, perform a shut/no shut on one of
the interface.

CSCsv63799
Symptoms: A router may reload if PfR is enabled and the number of flows exceeds the size of the
NetFlow cache. This is a stress condition.
Conditions: This symptom is observed when PfR is enabled (which also enables NetFlow).
Workaround: A possible workaround is to configure the following:
ip flow-cache timeout active 1
CSCsv66827
Symptoms: Clearing the SSH sessions from a VTY session may cause the router to crash.
Conditions: The symptom is observed when a Cisco 7300 series router is configured for SSH and
then an SSH session is connected. If the SSH session is cleared every two seconds using a script, the
symptom is observed.
Workaround: There is no workaround.
CSCsv73388
Symptoms: “Circuit-id-tag” and “remote-id-tag” attributes may be duplicated in packets sent to the
RADIUS server.
Conditions: The symptom is observed with Cisco IOS Release 12.2(31)SB13.
Workaround: Use Cisco IOS Release 12.2(31)SB14.
CSCsv73509
Symptoms: When “no aaa new-model” is configured, authentication happens through the local even
when tacacs is configured. This happens for the exec users under vty configuration.
Conditions: Configure “no aaa new-model”, configure login local under line vty 0 4 and configure
login tacacs under line vty 0 4.
