Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
• CSCed45698
Symptoms: Unused ports on a 1-port multichannel STM-1 port adapter (PA-MC-STM-1) may flap
even when they are not processing any traffic.
Conditions: This symptom is observed when there is congestion on used ports of the PA-MC-STM-1
and when a committed access rate (CAR) is configured on these used ports.
Workaround: There is no workaround.
• CSCed45746
Symptoms: Several prefixes for non-redistributed connected interfaces in different VRFs may be
partially bound to the same MPLS-VPN label, thus disrupting traffic bound to one or more of these
VRFs.
Conditions: This symptom can occur on a Cisco router that runs Cisco IOS Releases 12.2, 12.2T,
12.0S, 12.3 after the VRF interfaces have flapped. The symptom may occur in all code levels of
these releases.
Workaround: Clear the routes in the VRFs in sequence.
• CSCed46184
Symptoms: VPN sessions may not be established.
Conditions: This symptom is observed in an Xconnect configuration when a CFI interface goes
down after the VPN service is being established. This is a timing issue.
Workaround: Remove and reconfigure Xconnect.
• CSCed46669
Symptoms: On a Cisco 12000 series in a dual-RP (GRPs or PRPs) SSO mode, when certain
configuration commands are typed such as a nested policy-map command, the standby RP may
crash. While the RP reboots after the crash, it is not available to perform its standby function.
Conditions: This symptom is observed in Cisco IOS Release 12.0(22)S or a later release. A nested
policy-map command can cause this problem. In general, any configuration command that uses a
large amount of processor stack space, such as the nested policy-map command may, may cause the
standby RP to crash.
Workaround: There is no workaround.
• CSCed46747
Symptoms: After an SSO and before a standby RP is completely up, when you perform and OIR of
line cards, a configuration synchronization failure may occur and the standby RP may reload
unexpectedly.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S when you perform an OIR of an 8-port Packet-over-SONET OC-3c/STM-1 single
mode line card and a 4-port ISE Packet-over-SONET OC-12c/STM-4 single mode/IR SC connector
line card.
Workaround: Perform an OIR of these line cards after the standby RP is up.
• CSCed46785
Symptoms: A line card may reload when a policy map is removed.
Conditions: This symptom is observed when the policy map is child policy map of a policy map that
is attached to a Frame Relay DLCI or ATM PVC.
Workaround: Remove the service policy from the Frame Relay DLCI or ATM PVC before removing
the policy map.
