Caveats in Cisco IOS XE 3.9S Releases
• CSCud07085
Symptom: The serial interface on the OC-3 interface module remains in a down state.
Conditions: Occurs when you migrate from T1 mode to E1 mode using the OC-3 interface module.
Workaround: Issue an interface module reset (OIR) on the OC-3 interface module.
• CSCud07236
Symptoms: Upon reload few harmless messages will seen.
Conditions: Upon reload few harmless messages will seen.
Workaround: No impact on device.
• CSCud07642
Symptom: The ASR 903 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.
• CSCud09813
Symptoms: Timestamping not happening in CFM over xconnect down mep/PC
Conditions: When we configured cfm over xconnect down mep/PC from Asr903-Me3600
timestamping not happening in ASR903.
Workaround: No workaround.
• 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.
• CSCud23647
Symptom: BDI adjacency fails on the standby RSP.
Conditions: The issue can occur during an interface module (IM) reset or router reload.
Workaround: There is no workaround.
• CSCud25764
Symptoms: 903 part id to be populated in the discovery messages.
Conditions: Currently it is being displayed as "cisco, asr903" against Vendor in host by executing
this CLI "show nv satellite protocol discovery interface Bundle-Ether1000". This must be displayed
as cisco, ASR-903. This is mainly used by ASR9K ACT tool for rendering 903 graphic on Act tool.
Workaround: No workaround.
• CSCud26812
Symptom: The router CLI does not display some SFP PIDs
Conditions: Occurs when you install one of the following SFPs in the router:
– ONS-SI-155-L2
– ONS-SI-155-L1
