Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages
Error-Level Alarms
Recommended Action
In Real-Time Monitoring Tool, check the CallsActive and CallsInProgress counters for unusual activity
on the indicated H.323 trunk. If the CallsActive count is significantly higher than usual, a traffic load
issue may be occurring where the demand to send calls over the trunk is greater than the trunk's capacity.
Monitor the situation and collect existing trace files. If the ICTCallThrottlingEnd alarm is not issued in
a reasonable amount of time as deemed by your organization, contact TAC and supply the trace
information you have collected. For a routing loop condition, the CallsInProgress counter will be
significantly higher than usual. By examining trace files and CDR data for calls that occurred over the
indicated trunk, you may be able to detect a translation pattern, route list or other routing mechanism
that is part of the loop. Update the routing mechanism that resulted in the loop (generally the same
number is configured on both near end and far end devices) and then reset the affected route list in an
attempt to clear the route loop and if that fails, reset the affected trunk.
DeviceCloseMaxEventsExceeded
The TCP socket for the SCCP device has been closed due to excessive events in a 5-second period.
Under normal conditions, the device will reregister automatically.
The indicated SCCP device exceeded the maximum number of events allowed per-SCCP device. Events
can be phone calls, KeepAlive messages, or excessive SCCP or non-SCCP messages. The maximum
number of allowed events is controlled by the Cisco CallManager service parameter, Max Events
Allowed. When an individual device exceeds the number configured in that service parameter, Unified
CM closes the TCP connection to the device; automatic reregistration generally follows. This action is
an attempt to stop malicious attacks on Unified CM or to ward off excessive CPU usage.

Parameters
Total Events Received [UInt] IP Address [String] TCP Handle [String] Max Events Allowed [UInt]
Number Of Skinny Device Throttled
[UInt]
Recommended Action
Check the CCM trace data for the indicated SCCP device to determine the reason for the high number
of events. Confirm that the value configured in the Cisco CallManager service parameter, Max Events
Allowed, is a suitable number for your deployment.
InvalidIPNetPattern
An invalid IP address is configured in one or more SIP route patterns in Cisco Unified CM
Administration.
