Sample Packet Capture Configurations; Interface Capture Object Using A Filter And Direction - Nortel NN46110-602 Troubleshooting Manual

Sample packet capture configurations

This section provides sample configurations and the commands used to create
them.

Interface capture object using a filter and direction

In the following example, you configure a capture object called test-filter-in on
Fast Ethernet interface 0/1. This object captures inbound FTP traffic only.
Note: The filter used in this example is a predefined VPN Router filter.
If you need a filter that is not provided with VPN Router software, you
must create the filter before you configure the capture object.
To create and use this capture object, you run commands like the ones illustrated
in this example. These commands do the following:
1
Create a capture object called test-filter-in on Fast Ethernet interface 0/1.
2
Enter Capture Configuration mode for the object.
3
Set the direction for the capture to inbound.
4 Set the filter to capture FTP traffic only.
5
Exit Capture Configuration mode.
6
Start the capture.
