Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S2
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of Cisco
IOS Release 12.0(26)S4 or a later release but may also occur in other releases.
Workaround: There is no workaround.
• CSCef49138
Symptoms: When you enter the show policy-map interface interface-number command, a router
may crash because of a bus error exception.
Conditions: This symptom is observed on a Cisco 12000 series when the service-policy output
policy-map-name command is enabled on the same interface for which you enter the show
policy-map interface interface-number command.
Workaround: There is no workaround.
• CSCef53169
Symptoms: An outbound ACL with a log/log-input keyword changes the IP destination address in
the packets. As the result, packets that should be permitted are incorrectly denied.
Conditions: This symptom is observed on a Cisco platform that runs Cisco IOS Release 12.0(29)S
when the incoming interface for the packets is a tag-switching interface. The symptom is observed
irrespective of whether the interface with this outbound ACL is a tag-switching interface or not.
Workaround: Do not use the log/log-input keyword in the ACL.
• CSCef53475
Symptoms: Packet drops occur when traffic is sent below the shape rate that is defined in a service
policy.
Conditions: This symptom is observed on a Frame Relay interface when there are multiple DLCIs
that have service policies enabled. Each DLCI has a hierarchical policy with a shape rate in the class
default at the parent level and a child policy with LLQ and CBWFQ classes. When traffic to each
DLCI is just below the shape rate and the combined traffic through the interface is close to line rate,
packet drops occur on some DLCIs. The symptom does not occur when traffic is sent to one DLCI
at the time.
Workaround: Increase the shape rate to compensate for the scheduling inaccuracy.
• CSCef53570
Symptoms: When IPv4 multicast is configured on an interface and when hardware forwarding is
enabled, the interface stops forwarding all unicast and multicast traffic.
Conditions: This symptom is observed only on Cisco 12000 series Engine 2 line cards.
Workaround: Disable hardware forwarding.
• CSCef54021
Symptoms: After an SSO switchover has occurred, traffic stops on interfaces that have both an input
and an output policy attached.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Remove and re-attach the policies to the interfaces.
• CSCef54679
Symptoms: Time-based policing and shaping do not function on a 4-port OC-3 ATM ISE line card.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(28)S
when an input service policy is attached to a VC.
Workaround: There is no workaround.
