Cisco IOS XE 3S Release Notes for the Cisco ASR 903 Router
OL-26630-08
Caveats in Cisco IOS XE 3.9S Releases
Conditions: This symptom is observed when you move an OC-3 interface module with an ATM
configuration to a different bay and configure an ATM interface on the new bay.
Workaround: There is no workaround.
• CSCuc42117
Symptoms: The router does not include 0xff03 flag leading bits within ppp fragment messages.
Conditions: Occurs when the router has not negotiated ACFC.
Workaround: There is no workaround. Most remote devices should ignore this behavior by design,
but some devices may display unexpected behavior, such as for IPCP PROTREJ messages.
• CSCuc43719
Symptoms: ASR903 with dual RSP may crash.
Conditions: No specific trigger, but any configuration related to NBAR can make the box hit this
issue.
Workaround: Do not have any NBAR configurations on the box as these are not supported on
ASR903.
• CSCuc57130
Symptom: The router does not apply OC-3 interface module (IM) configurations.
Conditions: Occurs after an RSP switchover.
Workaround: There is no workaround.
• CSCuc59386
Symptoms: Continuous iomd crash on oc3im. Interfaces on oc3im not configurable, error message
seen :- stand-by dosen’t support this command
Conditions: Seen on a HA ASR903 setup with oc3im. Seen when a iomd crash happens on active
rsp and then standby iomd session handle is not cleared.
Workaround: Reload the stand-by rsp.
• CSCuc60148
Symptoms: System is not shutting down upon temperature sensor reaching ’SHUTDOWN’
threshold region.
Conditions: Temperature sensors reached shutdown threshold region
Workaround: IOS config command has to be explicitly configured to enable this system shutdown
behavior. ’facility-alarm critical exceed-action shutdown’
• CSCuc62784
Symptoms: Traces @ niles_if_count_initialize some times
Conditions: On performing Reload, Standby Reload, SSO
Workaround: No workaround. And these traces are displayed on the console and does not have any
functionality impact to the system.
• CSCuc64509
Symptom: ASR903 as PTP master transmits clock class corresponding to holdover state on fresh
bootup.
Conditions: ASR903 is not connected to any external frequency and Phase source and is using
freerun internal clock to provide synchronization.
Workaround: ASR903 PTP master should be locked to external frequency and phase source.
