Chapter
Caveats in Cisco IOS XE 3.10S Releases
• CSCud90457
Symptoms: The serial interface on the CE end connected to the CEM interfaces on PE remain down
on router reload with scaled configuration.
Conditions: This symptom is observed when you have CESoP and SAToP scaled circuits and reload
the router.
Workaround: Perform an IM OIR to resolve the issue.
• CSCud93007
Symptom: If you use the command channel-group 1 mode active on a interface, the router does
not reject the command.
Conditions: This issue is observed after you configure a trunk EFP MEP using the ethernet cfm
mep domain v7 mpid 1537 service v7137 command on an interface.
Workaround: There is no workaround.
• CSCud96866
Symptom: The router displays the following symptoms:
– Object download failures.
– OSPF traffic flaps.
– High CPU utilization.
– Bundling and unbundling of port-channel member links.
– Slow console updates.
– Remote MEP learning failures.
Conditions: This issue is observed when you configure CFM offloaded MEPs on a port-channel
interface at a high scale and use the shutdown and no shutdown command on the port-channel
interface.
Workaround: There is no workaround.
• CSCue00045
Symptom: Data traffic drops for a few groups when you use the shutdown and no shutdown
commands on the interface.
Conditions: This issue is observed if join request is sent to the router within three minutes.
Workaround: There is no workaround.
• CSCue01419
Symptom: EIGRP neighborship is lost on OC3IM and OC12 IM interfaces configured on port 0.
Conditions: This issue is observed only on interfaces that are configured on port 0 of OC3IM or
OC12 IM. It is not seen on ports 1,2, or 3.
Workaround: Use the shutdown and no shutdown commands on the interfaces configured on port
0. Alternatively, remove and reconfigure EIGRP.
• CSCue03418
Symptoms: Intermittently OSPF protocol flaps are noticed when you use the redundancy
force-switchover or the switchover command. It can cause about 20 to 30 seconds of traffic loss.
Conditions: This symptom is observed while performing an SSO or when using the redundancy
force-switchover command and on a HA system with 6 seconds as OSPF dead interval.
Workaround: Increase the dead interval value.
