Filtering debug monitor output

The output of the debug monitors can be filtered using the following command to let the terminal only print important information. The specified expression is a regular expression, which is used by the filter to select important lines.

Mode: Configure

Step	Command	Purpose
1	[name](cfg)# [no] terminal monitor-filter	Enables the monitor filter using the
	<expression>	specified expression.

The following example activates a filter, which causes the debug monitors to print only lines containing the word ERROR on the terminal:

terminal monitor-filter .*ERROR

Note Only one filter expression can be active at a time. If you enter the command a second time, the new filter expression will replace the old one.

The following command will disable the filter completely:

no terminal monitor-filter

Verifying IP connectivity

This procedure describes how to use the ping command to test IP connectivity. It verifies that your SmartNode can communicate with such hosts as a gatekeeper, and IP phone, a registrar, and other VoIP gateways.

Use Telnet to access your SmartNode, then use the ping command to verify that an IP packet can be sent to, and received from, all hosts with which the SmartNode should be able to communicate (e.g. Gatekeeper, IP phone, Registrar, other VoIP gateways).

Mode: Administrator execution

Step	Command	Purpose
1	unit#ping ipaddress [number-of-packets]	Determines whether an IP host can be contacted.
	[timeout seconds]

Example: Verify IP connectivity

The following example uses the ping command to test connections to remote hosts 192.195.23.10 and 172.16.40.122. The results show an unsuccessful attempt to contact host 192.195.23.10 (as indicated by the “No
