Caveats in Cisco IOS XE 3.8S Releases
– You issue the clear ip route * command
– You issue an interface module reset (IM OIR)
Workaround: There is no workaround.
• CSCud09315
Symptom: The show ptp clock running domain 0 and show platform ptp all commands do not
display a configured slave clock.
Conditions: Occurs when you issue a shutdown/no shutdown on the link between a boundary
clock and a master clock during while the boundary clock is in phase alignment.
Workaround: Remove and restore the PTP configuration on the boundary clock.
• CSCud12587
Symptom: When handling IS-IS packets, the router punts the traffic to the Route Switch Processor
(RSP) and applies policing to limit the traffic to 1 Mbps.
Conditions: Occurs when you enable IS-IS over an Ethernet over MPLS (EoMPLS) connection.
Workaround: Use IS-IS over another connection type or limit the IS-IS traffic to less than 1 Mbps.
• CSCud13535
Symptom: The router drops imposition traffic sent to a neighbor device over a VPLS pseudowire.

Workaround: Increase the REP timer to above 500 milliseconds or disable the MAC limiting
feature.
• CSCud15841
