Caveats in Cisco IOS XE 3.9S Releases
• CSCud55377
Symptom: The router crashes.
Conditions: Occurs when you configure offloaded CFM for xconnect sessions at a high scale.
Workaround: There is no workaround.
• CSCud55695
Symptom: When you apply an QoS policy with a port level class-default configuration containing
a shaper value to a serial interface. the router applies the shaper value to the channel-level PIR for
all serial interfaces on the IM.
Conditions: Occurs when you apply QoS policy with a port level class-default configuration
containing a shaper value to a serial interface.
Workaround: Add a dummy class-default level at the top of the policy and apply the shaper as a
child policy of this class.
• CSCud55799
Symptoms: Multiple priority commands get accepted per policy
Conditions:
Have a policy-map with priority configured in one of its classes. add another class with policer first
and then with priority. this policy must be rejected.
Workaround: none
• CSCud56262
Symptom: The router stops passing traffic on virtual circuits.
Conditions: Occurs an MPLS-TE/FRR configuration with L2VPN after you issue a stateful
switchover (SSO).
Workaround: Reload the router.
• CSCud56364
Symptoms: Convergence time for POS links for rsp SSO is about 4-7 seconds.
Conditions: All 4 POS links must be created on OC3IM. Issue not seen on port 0 of OC3IM.
Workaround: None. Expected to be fixed.
• CSCud60410
Symptom: The router drops EFP traffic.
Conditions: Occurs when you add a new EFP to an existing bridge domain interface (BDI) while
running L3 multicast.
Workaround: Issue a shutdown/no shutdown on the Ethernet interface and issue the clear ip
mroute command.
• CSCud64034
Symptoms: Interfaces not coming up
Conditions: 1) Configure t1 interfaces 2) Verify ping & they are coming up 3) Perform SSO 4)
Verify Ping again & traffic 5) Unconfigure t1 interfaces .6) Reload the standby 7) Configure t1
interfaces 8) T1 interfaces are not coming up
Workaround: IM OIR on box
