Troubleshooting Routers

B-34

These utilities are also available in the /perm/pkt_convert directory on the Bay

Networks FTP ﬁle server. Refer to Chapter 8 for ﬁle transfer instructions.

The Network General Sniffer reads MCT1 Packet Capture ﬁles as synchronous

ﬁles.

You can convert HSSI packets only if the protocol is standard synchronous, such

as PPP. You cannot convert packets if the protocol is HPTP protocol.

Packet Convert does not support the bisynchronous protocol.

Convert a Packet Capture ﬁle as follows:

1. Retrieve a copy of the ﬁle from the router.

Go to the following sections for instructions:

—“Getting the Name of the P

acket Capture File”

—“Using FTP to

Transfer the File,” “Using TFTP to Transfer the File,” or

“Using XMODEM to

Transfer the File”

2. Make sure the ﬁlename does not have an extension and is nor more than 8

characters.

3. Access the directory containing the Packet Convert directory.

4. Enter the following command to convert the ﬁle:

pktconv

<ﬁlename>

Packet Capture creates a new ﬁle that you can copy to a DOS-formatted

diskette and insert in the Sniffer. The name of the ﬁle begins with the Packet

Capture ﬁlename and ends with the extension the Sniffer requires.

Examples:

• For a CSMA/CD Packet Capture ﬁle named PCAP0400, you enter

pktconv pcap0400

Packet Convert creates a Sniffer ﬁle named PCAP0400.ENC.

• For a TOKEN Packet Capture ﬁle named PCAP0300, you enter

pktconv pcap0300

Note: You must set the size of the packets to one of the values the Sniffer

supports before you capture them. Go to “Specifying the Number of Bytes in

Each Packet to Copy” for instructions.
