Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: Router crashed while reconfiguring a three-level policy.
Conditions: Seen on a Cisco 7200 router.
Workaround: There is no workaround.
CSCsl63212
Symptoms: L2TP network server (LNS) router crashes while establishing virtual private dial-up
network (VPDN) and shutting down client interface.
Conditions: Occurs while making call from client to LNS with specific configurations.
Workaround: There is no workaround.
CSCsl63311
Symptoms: On a Cisco Catalyst 6500 Series Switch, NAT traffic may be software switched. This
may result in high CPU utilization.
Conditions: The symptom is observed when the NAT traffic egress on an interface is configured as
an ISL L3 sub-interface.
Workaround: Use DOT1Q instead of ISL.
Alternate Workaround: Make the connection a Layer 2 ISL trunk and create an SVI for each
sub-interface.
CSCsl63494
Symptom:
AAA server does not count active user sessions correctly. User authentication may be denied by the
AAA server because max session limit has been reached.
Conditions:
This may occur with AAA authentication, when max session limit is configured on Cisco Secure
ACS server (may happen with other AAA servers too). When user initiates X.25,ssh,rsh,rlogin or
telnet sessions and later disconnects them, AAA server does not decrement active sessions counter
due to wrong attributes present in the accounting records sent by the device. Eventually, the
misbehaving counter may reach max session limit, and user will be denied a login.
Workaround: Removing max session limit can be considered.
CSCsl64890
Symptoms: Ping fails for packet sizes greater than 1500.
Conditions: Applicable to RSP720 supervisor and with Filer Feature in Cisco IOS Release
12.2(33)SRC. This bug is not applicable to any other releases.
Workaround: There is no workaround.
CSCsl65047
Symptoms: Back-to-back ping fails after configuring "native" on subinterface.
Conditions: Initially ping works fine, but packets go out tagged, which should not be the case. On
doing a shut/no shut on one sub-interface with native configured cause ping to fail since the side
that was flapped starts sending untagged ping packets (which is the expected behavior). The remote
side that has not been flapped, expects tagged packets.
Workaround: Do shut/no shut on both ends of the sub-interface.
CSCsl65087
Symptoms: SIP200 linecard crashes due to memory corruption when high traffic passes through on
a software based dLFI bundle which has ACFC/PFC configured.
