Chapter
Caveats in Cisco IOS XE 3.8S Releases
• CSCud76957
Symptom: Traffic gets dropped during egress when service instance is configured.
Conditions: This issue occurs when service instance is configured.
Workaround: Unconfigure the service instance and reconfigure it again.
• CSCud90890
Symptom: Routing over Trunk EFP over port-channel does not work on member ports associated
with ASIC #1.
Conditions: This issue occurs when a Trunk EFP on port-channel has members on ASIC#1, the
routing traffic does not egress on those ports.
Workaround: There is no workaround.
• CSCud90955
Symptom: The following console messages are seen whenever BFD session is created or modified.
Jan 3 06:34:52.481: %HANDOFF_FUD-6-QDR_MULTI_BIT_ERROR_START: SIP1: nile_mgr:
Handoff FPGA could encounter MBE, check at start of create update BFD session
Jan 3 06:34:52.481: %HANDOFF_FUD-6-QDR_MULTI_BIT_ERROR_END: SIP1: nile_mgr: Handoff
FPGA could encounter MBE, check at end of create update BFD session
Jan 3 06:34:53.167: %HANDOFF_FUD-6-QDR_MULTI_BIT_ERROR_START: SIP0: nile_mgr:
Handoff FPGA could encounter MBE, check at start of create update BFD session
Jan 3 06:34:53.167: %HANDOFF_FUD-6-QDR_MULTI_BIT_ERROR_END: SIP0: nile_mgr: Handoff
FPGA could encounter MBE, check at end of create update BFD session
Conditions: This issue occurs when BFD sessions are created or modified.
Workaround: There is no workaround. This issue has no service impact.
• CSCud96604
Symptom: On system reset or reload, all traffic on certain Ethernet Flow Point (EFP)s do not egress.
Conditions: This issue occurs when traffic completely stops on certain EFPs.
Workaround: Delete and reconfigure EFPs.
• CSCue00049
Symptom: Classification does not work properly with non-matching traffic when IP ACL is used.
Conditions: This issue occurs only for class-based ACL match. The ACL class are classified
properly and other classes based on DSCP or class-default do not work
Workaround: There is no workaround.
• CSCue10037
Symptom: Crash observed on the router.
Conditions: This issue after when CFM is offloaded and MEPs with 3.3ms were scaled on
port-channel with Trunk EFP. This issue occurs after shutdown command followed by a no
shutdown command is executed on the member links of port-channel.
Workaround: Configure around 50-100 CFM sessions.
• CSCue11444
Symptom: Split horizon configurations does not clear with Layer2 multicast packets.
Conditions: This issue occurs when Ethernet Flow Point (EFP)s with split-horizon are configured.
Workaround: Perform a shutdown followed by no shutdown. Configure EFP first before moving
into split-horizon group.
