Caveats in Cisco IOS XE 3.10S Releases
• CSCuh51651
Symptom: CPP download failures and CFM remote MEPS not learnt.
Conditions: This issue occurs during configuring CFM offload scaled configurations using TFTP.
Workaround: There is no workaround.
• CSCuh51702
Symptom: The system shuts down after 5mins irrespective of ambient temperature after removing
the fan tray.
Conditions: This issue occurs after removing the fan tray.
Workaround: There is no workaround.
• CSCuh81135
Symptom: Port speed configuration is changed automatically on changing the SFP module.
Conditions: This issue occurs on changing the SFP module.
Workaround: There is no workaround.
• CSCuh85990
Symptom: Some CFM MEPs are not learnt when configuring large number (about 1K) on the router.
Conditions: This issue is seen only if large number of MEPs are configured.
Workaround: Remove and re-apply the configuration.
• CSCuh92939
Symptom: Traffic drop occurs after replacing a Cu SFP with a fiber FP
Conditions: This issue occurs after replacing Cu SFP with fiber SFP after an SSO is performed.
Workaround: Perform an IM OIR.
• CSCuh99117
Symptom: Packet drops for some of the prefixes in MPLS network are observed.
Conditions: This issue occurs when MPLS Layer3 VPN is configured on the router with MVPN
template.
Workaround: There is no workaround.

Symptom: CFM download error-objects are observed when CFM peers are reloaded or IM OIR is
done on a scaled VPLS and CFM setup.
Conditions: This issue occurs on the router with 250 or more CFM MEP sessions and more than
1250 Layer2 virtual circuit sessions.
Workaround: There is no workaround.
