Caveats in Cisco IOS XE 3.9S Releases
• CSCuc71723
Symptom: The router erroneously accepts a service-policy configuration on a CEM interface and
displays it within the running configuration.
Conditions: Occurs when you configure a service-policy on a CEM interface.
Workaround: There is no workaround.
• CSCuc74205
Symptoms: Tracebacks displayed continuously on performing IM OIR
Conditions: Have CEM, ATM, IMA configured on a TDM IM. Now, on performing IM OIR, notice
this traceback continuously on active RSP. This is noticed on performing OIR operation every 2 out
of 5 times.
Workaround: No workaround
• CSCuc81334
Symptom: The router selects a clock source attached to standby RSP.
Conditions: Occurs after a stateful switchover (SSO).
Workaround: Remove and restore the clock source configuration.
• CSCuc81416
Symptoms: Traces may be seen on active with SNMP configuration
Conditions: Seen when Hard pull of Standby is done
Workaround: Do soft reset/ sso switchover
• CSCuc83088
Symptom: The router drops traffic during stateful switchover (SSO).
Conditions: Occurs when the router is running HSRP or VRRP; the issue only occurs when the
destination MAC address is a virtual MAC (vMAC) address.
Workaround: Change the traffic priority and detour traffic prior to the SSO.
• CSCuc87791
Symptom: The router selects a network clock source before the wait-to-restore timer has expired.
Conditions: Occurs under the following conditions:
– A clock source fails, triggering the wait-to-restore timer (which specifies how long the before
including a restored clock source in the clock selection process.
– The clock source becomes active and fails a second time before the wait-to-restore time has
passed.
Workaround: There is no workaround; in some cases you can clear the issue by removing and
restoring the clock source configuration.
• CSCuc91582
Symptom: Adding EFP to Bridge-Domain fails and errors are seen when reloading with Cisco IOS
XE Release 3.7.1a.
Conditions: This symptom is observed when reloading the Cisco ASR 903 with Cisco IOS XE
Release 3.7.1a, when EFP and PW are in the same Bridge-Domain.
Workaround: Post reload, remove the EFP configurations, and configure PW first and then EFP.
