Troubleshooting Routers

Establish an FTP, TFTP, or XMODEM connection to the router from an

MS-DOS PC or Sun workstation to transfer a copy of the file; then, use the

Packet Dump utility to display the packets in hexadecimal format.

See “Using a Sun Workstation or MS-DOS PC to Display Packets

” on

page B-31

The Packet Dump utility shows the same information about each packet as the

Technician Interface, but it does not provide options for specifying the packet

by number or quantity.

See “Displaying the File with Packet Dump

” on page B-35.

Implementation Notes

Packet Capture copies only packets that are error free; it does not copy packets

containing errors.

Packet Capture saves the MAC addresses in native media format.

Packet Capture does not display frame check sequence (FCS) fields.

On a BayStack ARN router, Packet Capture prompts for the module number of the

interface. Specify 1 for synchronous interfaces. For interfaces that are configured

with a WAN service other than synchronous (for example, BOT or ISDN

interfaces), use the module number listed in Table B-1

Table B-1. Packet Capture Module Numbers for ARN Interfaces

(Except Synchronous)
