Critical-Level Alarms
Critical-Level Alarms
The critical-level alarm equals 2 and action may need to be taken immediately; auto-recovery is
expected, but monitor the condition.
This alarm acts similar to the alert-level alarm but not necessarily requiring an immediate action. A
system-affecting service had a failure but recovered without intervention. Examples follow:
• Service crashed due to an error that could not be handled but a watchdog process exists that will
restart the service. The crash does not necessarily require immediate action. Examples are:
–
Out of memory conditions
–
Uninitialized variables
–
Memory scribblers
• Unexpected code error occurred that could not be handled but for which the system automatically
restarts.
BChannelOOS
The B-channel is out of service. The B-channel indicated by this alarm has gone out of service. Some of
the more common reasons for a B-channel to go out of service include are as follows:
• Taking the channel out of service intentionally to perform maintenance on either the near- or far-end
• MGCP gateway returns an error code 501 or 510 for a MGCP command sent from Cisco Unified
Communications Manager (Cisco Unified CM)
• MGCP gateway does not respond to an MGCP command sent by Cisco Unified CM three times
• Speed and duplex mismatch exists on the Ethernet port between Cisco Unified CM and the MGCP
gateway.
