Performing a packet capture

You can use the packet dump utility to capture all of the data transmitted

and received on an interface of the Avaya 3100 Mobile Communicator

Gateway for a period of time (a capture session). After the capture session

completes, you can save the packet dump as a

.cap file.

Attention: Before performing a packet capture, confirm that the server

contains tcpdump. If necessary, install tcpdump in /usr/sbin, and change

the permissions by logging on as root and using the command

chmod u+s /usr/sbin/tcpdump

To open the .cap files for troubleshooting and analysis, you require the

protocol analyzer called Wireshark (formerly Ethereal).

Prerequisites

• You must be logged into the Avaya 3100 Mobile Communicator Web

Administration Console as administrator. For more information, see

"Logging on to the Avaya 3100 Mobile Communicator Web Console as

an administrator" (page 11).
