OL-26630-08
Caveats in Cisco IOS XE 3.9S Releases
Workaround: Flap the backup path interface
• CSCue43250
Symptoms: IMA config won’t be parsed correctly after router reload when the A903-IM40S is
inserted in Bay4/Bay5 of the ASR903 router
Conditions: when the IMA and ATM interfaces are adjacent. happens only for IM inserted on Bay
4 or above.
Workaround: insert the IM in bay 0 bay 3 if you want the IMA and ATM parsing to work. or
reconfigure the ATM and IMA interfaces, it would work.
• CSCue45306
Symptoms: CEM circuits configured over TDM IM go down after SSO.
Conditions: on SSO, CEM circuits configured over TDM IM are down.
Workaround: Router reload.
• CSCue45498

• CSCue47317

• CSCue52774
Symptoms: observed with A900-IMA4OS IM in ASR903 box. only when the port above 0 is used
for clock-source, the clocking is not received by the system correctly.
Conditions: when the port above 0 is used for the clock source. issue is seen due to wrong
conversion.
Workaround: 1. use port 0 for clock-sync 2. or insert the SFP in the odd port(protect ones) adjacent
to actual port and using a optical splitter, the cable can be fed to this odd port which can recover the
proper clocking for the given port.
• CSCue52968
Symptoms: Ping fails and traffic stops through Multilink bundle when CHAP authentication is
enabled
Conditions: This is seen when PFC and ACFC is configured.
Workaround: None, in case PFC and ACFC is configured.
