Nortel Networks NN46110-602 Sample packet capture configurations, Exit Capture Configuration mode

Chapter 5 Packet capture 121

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-inon 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:

1Create a capture object called test-filter-in on Fast Ethernet interface 0/1.

2Enter Capture Configuration mode for the object.

3Set the direction for the capture to inbound.

4Set the filter to capture FTP traffic only.

5Exit Capture Configuration mode.

6Start the capture.

CES#capture add test-filter-in FastEthernet 0/1

CES#capture test-filter-in

CES(capture-ethernet)##direction inbound

CES(capture-ethernet)#filter "permit FTP"

CES(capture-ethernet)#exit

CES#capture test-filter-in start
