Conditions: This issue occurs when the TCAM entries exceed the limit during dynamic
modification of service-policy.
Workaround: There is no workaround.
• CSCuf43992
Symptom: The router crashes if you configure local span.
Conditions: This issue is observed when you configure local span on the router.
Workaround: Use another Encapsulated Remote Switched Port Analyzer (ERSPAN) configuration
to work as local span with source and destination ERSPAN session configured in one router.
• CSCuf45656
Symptom: Cisco ASR 903 Router crashes with segmentation fault.
Conditions: This issue occurs during multicast convergence on EFP’s configured with split horizon.
Workaround: There is no workaround.
• CSCuf53527
Symptom: Class of Service (CoS) inner value gets copied into the CoS value.
Conditions: This issue occurs when configuring Q-in-Q without rewrite service instance.
Workaround: To ensure CoS inner value does not get copied, apply QoS policy-map.
• CSCuf65301
Symptom: Micro flaps observed on the router.
Conditions: This issue is seen when system is kept idle for hours.
Workaround: There is no workaround.
• CSCuf79397
Symptom: F1 is stuck in init state after the standby RSP reloads.
