Chapter
Caveats in Cisco IOS XE 3.7S Releases
• CSCud07642
Symptom: The ASR 903 router is unable to pass traffic to the ASR 9000.
Conditions: Occurs with a clear-channel ATM over MPLS configuration using AAL0
encapsulation.
Workaround: Enable MPLS control-word on the ASR 9000.
• CSCud09632
Symptom: The router does not correctly update the J0 byte on the OC-3 or OC-12 interface module.
Conditions: Occurs in a back-to-back configuration with two ASR 903s passing SONET traffic.
Workaround: There is no workaround.
• CSCud15785
Symptom: The router experiences flapping on REP connections.
Conditions: Occurs under the following conditions:
– MAC limiting is enabled and a MAC address is at the maximum value
– REP is configured with a 200 millisecond LSL ageout timer
Workaround: Increase the REP timer to above 500 milliseconds or disable the MAC limiting
feature.
• CSCud15841
Symptom: The clear ip mroute * command causes resource leakage.
Conditions: Occurs when you issue the clear ip mroute * command while IP multicast is enabled.
Workaround: Reload the router.
• CSCud17457
Symptom: The router drops IP multicast traffic.
Conditions: Occurs when you perform the following actions:
– Configure EFPs as members of a port channel containing a single interface.
– Remove the configuration for the EFPs
– Remove the interface from the port channel
– Add the EFPs back onto the interface
Workaround: Reload the router or issue a stateful switchover (SSO).
• CSCud23698
Symptom: The router stops applying classification and marking for a class.
Conditions: Occurs when you remove a priority level while using dual priority for the
class-map.
Workaround: Remove and reattach the policy-map on the interface.
• CSCud28982
Symptom: The router does not process egress CoS marking on an Ethernet service instance.
Conditions: Occurs when you configure QoS on an Ethernet service instance that is a member of a
bridge-domain and uses dot1q encapsulation.
Workaround: There is no workaround.
