Chapter
Caveats in Cisco IOS XE 3.8S Releases
• CSCue27652
Symptom: ATM interfaces get deleted after SSO is performed.
Conditions: This issue occurs after an the ATM interfaces are deleted on the standby RSP after an
IM OIR is performed.
Workaround: There is no workaround.
• CSCue30481
Symptom: The router does not lock to the syncE clock source after reload. It will be in Ql-failed
state.
Condition: Reload the router with saved syncE configuration.
Workaround: Unconfigure and configure the clock source.
• CSCue32753
Symptom: The OC-3 interface modules are lost after a In Service Software Upgrade (ISSU) is
performed on the Cisco ASR 903 router and configuration mismatch errors are displayed on router
console. The standby RSP reaches standby-hot state causing continuous IOMD crash messages at
regular intervals.
Conditions: This issue occurs when ISSU is performed.
Workaround: There is no workaround.
• CSCue34597
Symptom: CHAP authentication process timed out. The PPP interface and multilink bundle does
not come up.
Conditions: This issue occurs when PPP or MLPPP is configured and PPP authentication is
enabled.
Workaround: Remove CHAP authentication from interface.
• CSCue40020
Symptom: Interior Gateway Protocol (IGP) flap or MPLS-enabled interface flap with 600 Layer2
VPN configured and 6000 Layer3 VPN configured can cause a crash.
Conditions: This issue occurs after the IGP flaps continuously.
Workaround: Configure IGP routes less than 100. Scale of Layer2 or Layer3 VPN configuration
should be less than 100 to avoid a crash.
• CSCue42315
Symptom: CPU hog messages and IOMD crash observed on the Cisco ASR 903 router.
Conditions: This issue occurs with OC-3 interface module after executing the shutdown command
followed by a no shutdown command of the multilink bundle when traffic is sent with a packet size
greater then 1500 byte.
Workaround: There is no workaround.
• CSCue43250
Symptom: IMA configurations cannot be parsed correctly after a router reload.
Conditions: This issue occurs after the A903-IM40S is inserted in bay 4 or bay 5 of the Cisco
ASR903 router and when the IMA and ATM interfaces are adjacent.
Workaround: Insert the IM in bay 0 or bay 3 for the IMA and ATM parsing to work or reconfigure
the ATM and IMA interfaces.
