OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S2
Workaround: There is no workaround.
Further Problem Description: The fix for this caveat causes packets that are sent to the RSP for
switching to be dropped. Distributed forwarded packets are forwarded correctly.
• CSCeg30179
Symptoms: Removing a policy that has shape and bandwidth in the same class (in that same order)
may cause a router to crash.
Conditions: This symptom is observed when the router functions under a traffic load.
Workaround: There is no workaround.
• CSCeg31912
Symptoms: Ingress policing and bandwidth percent per-class do not function and limit traffic at the
configured bandwidth for MLFR links. The output of the show policy-map interface command
shows the configured bandwidth which differs from the actual bandwidth.
Conditions: This symptom is observed on a Cisco 7500 series after the router is reloaded.
Workaround: Remove the service policy and re-apply it to interface to enable correct calculation of
the interface bandwidth.
• CSCeg33229
Symptoms: A VIP may crash when an ingress service policy is removed from an MFR interface.
Conditions: This symptom is observed on a Cisco 7500 series while traffic is being processed on the
MFR interface.
WorkAround: There is no workaround.
• CSCin74180
Symptoms: Spurious memory accesses may occur on a VIP in which one or more channelized port
adapters are installed. The CPU utilization may increase to 99 or 100 percent, causing the
performance of the VIP to be impacted.
Conditions: These symptoms are observed on a Cisco 7500 series that runs Cisco IOS
Release 12.3(6) but may also occur in other releases.
Workaround: There is no workaround.
• CSCin75482
Symptoms: A router may hang or crash when PA-MC-8TE1+ or PA-MC-2T3+ interfaces are
congested with traffic and a QoS configuration such as shaping is configured on the interfaces.
Conditions: This symptom is observed on a Cisco 7200 series but may also occur on other platforms.
Workaround: Avoid congesting the interfaces.
• CSCin78324
Symptoms: A Cisco 7200 VXR router may hang.
Conditions: This symptom is observed on a Cisco 7200 VXR router that has a PA-MC-8TE1 and
that is configured for IPSec encryption, either via tunnel protection or via a crypto map.
Workaround: Disable IPSec encryption.
• CSCin78325
Symptoms: A serial interface of a PA-MC-8TE1+ continues to process packets even after the
interface is placed in the “ADMINDOWN” state. The counters in the output of the show interfaces
serial command may continue to increment even if the serial interface is shut down.
