Packet Capture from Extreme Networks EXOS CLI

If you need to perform a packet capture you can use the following below to get this exported to a PCAP file you can then open in WireShark.

debug packet capture ports 1 on file-name voip001 count 100

debug packet capture off

ls /usr/local/tmp

You can then TFTP off the file with the following:

tftp put <TFTPServer> vr "VR-Default" /usr/local/tmp/voip001.pcap

I normally use TFTP32/64 on the machine to which i’m TFTPing, but this has had problems recently.

Remember to delete the PCAP file once you’re done so its not using up disk space on your switch!
