Cisco IOS XE 3S Release Notes for the Cisco ASR 903 Router
OL-26630-08
Chapter
Caveats in Cisco IOS XE 3.8S Releases
– Remove the interface from the port channel
– Add the EFPs back onto the interface
Workaround: Reload the router or issue a stateful switchover (SSO).
• CSCud19563
Symptom: The T1/E1 interface module on the standby RSP crashes repeatedly.
Conditions: Occurs when the standby RSP is booting and there is a clock configured on the T1/E1
controller.
Workaround: Remove the clock configuration prior to booting the standby RSP and restore the
configuration afterwards.
• CSCud22601
Symptom: MPLS-TP tunnels remain down after the standby RSP boots.
Conditions: Occurs when you boot the standby RSP after applying an MPLS-TP configuration and
performing an SSO. The issue occurs rarely.
Workaround: Issue a shutdown/no shutdown on the MPLS-TP tunnel. A nonintrusive workaround
is to cause a flap on the protect label switched path (LSP) by reconfiguring the path or physically
shutting down and restoring the interface.
• 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.
• CSCud24704
Symptom: The router crashes.
Conditions: Occurs when you perform an interface module OIR (reset) on the gigabit Ethernet
interface module while the standby RSP is booting.
Workaround: Perform the IM OIR after the standby RSP boots.
• CSCud25813
Symptom: The router drops IP Multicast traffic.
Conditions: Occurs under the following conditions:
– You initiate multicast traffic to a single L3M group.
– You configure 50 EFPs with corresponding bridge domain interfaces (BDIs) and initiate
IGMPv2 join traffic to a single multicast group.
– You add 25 EFPs with 25 bridge-domain interfaces (BDIs) at a 1:1 ratio.
– You remove 10 EFPs from the group of 50 and add the same EFPs to the group of 25.
– The newly added EFPs do not receive any traffic.
Workaround: Reload the router or issue a stateful switchover (SSO).
• CSCud26154
Symptom: The router displays incorrect ENV readings.
Conditions: Occurs when you switch off one power supply unit in a dual power supply
configuration.
