Caveats in Cisco IOS XE 3.7S Releases
CSCue26927
•
Symptom: Alarms are not forwarded in Circuit Emulation Services over Packet (CESoP).
Conditions: This issue occurs when alarms are not forwarded when AC goes down.
Workaround: There is no workaround.
CSCue30481
•
Symptom: The Cisco ASR 903 router does not lock to the synchronous Ethernet clock source after
reload. It remains in Ql-failed state.
Conditions: This issue occurs after a reload of router with saved synchronous Ethernet clock
configurations is performed.
Workaround: Unconfigure and reconfigure the clock source.

•
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.
Try unconfiguring the OC-3 interface module configuration and reconfigure again. Reload the
standby RSP to stop IOMD crashes. Perform a hard OIR or process kill if the interface module enters
out of service state

•
Symptom: Traffic stops flowing with a combination of Bandwidth Remaining Ratio (BRR) and
policer in different class-maps under a policy.
Conditions: This issue occurs when the bandwidth remaining ratio is configured as a combination
of police with cir (total brr and police cir equal to 1000M).
Workaround: Configure total BRR and police cir lesser than 1000M. For example, class A Police
cir 100m and class B BRR 90% fails but BRR 89% works.

•
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.
CSCue45498
•
Symptom: CPU utilization is high when sending traffic with varying source MAC addresses for
multiple streams for a bridge domain (BD).
Conditions: This issue occurs when port-channel is configured as Ethernet Flow Point (EFP) for the
BD and mac-limit is configured to 0 for that BD.
Workaround: There is no workaround.
