Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
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.
• CSCef54308
Symptoms: An Engine 4 plus (E4+) interface polices traffic although no policing is configured.
Conditions: This symptom is observed on a Cisco 12000 series when MQC is configured with
policing on an E4+ interface and then MQC is removed from the interface.
Workaround: Reload the E4+ line card.
• CSCef54624
Symptoms: The secondary RP of a Cisco 12816 cannot be booted and is stuck in the “RDY RP”
state.
Conditions: This symptom is observed on a Cisco 12816 that runs an interim release for Cisco IOS
Release 12.0(30)S and is independent of the redundancy modes that is configured (RPP, RPR+, or
SSO). The Cisco 12816 is configured with a PRP-1 in slot 0 and a PRP-2 in slot 2. Note that this
caveat is resolved in Release 12.0(30)S.
Workaround: There is no workaround.
• 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.
• CSCef54779
Symptoms: Under a rare condition, when a main interface switches over to a backup interface on
4-port GE line card, a ping to another neighboring interface that is not at all related to the backup
interface fails. A sniffer trace shows that the Src/Dst MAC address in the ICMP reply is that of the
backup interface.
Conditions: This symptom is observed on a Cisco 12000 series when you repeatedly disable the
main interface that is associated with a backup interface.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected interface.
• CSCef54855
Symptoms: A 6-port channelized T3 interface may not come up after booting, and a traceback may
be generated.
Conditions: This symptom is observed on a Cisco 10000 series that runs a Cisco IOS interim release
for Release 12.0(30)S. However, this caveat is resolved in Release 12.0(30)S.
Workaround: There is no workaround.
• CSCef55373
Symptoms: The BGP process can take up 100 percent of the CPU for an extended period of time
when 6PE is configured.
