Capturing packets to disk file

To configure PCAP, you must first enter CLI Capture Configuration Mode. For more information about CLI Capture Configuration Mode, see Nortel VPN Router Using the Command Line Interface.

There are five CLI commands for capturing packets to disk file. These commands are:

•filepath—sets the PCAP file path

•buffersize—sets the size of the RAM buffer

•filesize—sets the size of a disk capture file

•maxfiles—sets the maximum number of disk capture files

•capture-all—sets PCAP capture mode to either loss or no loss

The following sections describe each of these commands.

Setting the PCAP file path

To set the file path to save PCAP files, from CLI Capture Configuration Mode, enter:

filepath <path>

where path is the path to save the PCAP files.
