Nortel VPN Router Troubleshooting

• Delete a capture object or capture files when you no longer need them to free

up memory or disk space.

• Do not run capture objects for physical interfaces or tunnels at the same time

that you run the global IP capture object (some packets are captured more

than once).

Enabling packet capture on a VPN Router

You must have a serial connection to capture packets. You cannot enable packet

capture through a Telnet session.

To prepare to run packet capture on the VPN Router:

1 If necessary, boot the VPN Router with a software version that has the PCAP

feature.

2 Turn on the terminal or PC.

3 Configure the terminal or PC as follows:

• 9600 baud

• 8 data bits

• 1 stop bit

• No parity

• No flow control

4 Connect the serial cable (supplied with the VPN Router) from the VPN

Router serial port to the terminal or to the communications port on the PC.

5 On the PC, start HyperTerminal

or another terminal emulation program and

click Enter.

The Welcome window appears.
