How to Mirror a port on a CXi L2 Switch

by  sarond  Posted    (Edited  )
To perform port mirroring on the integrated switch of a CXi you must first get into the VXWorks shell.

Firstly secure telnet into the controller, I use PuTTY and connect via RAW and port 2002.

Enter your username and password.

Enter these commands to enable port mirroring:
mipsdb_debug 51, ôdestination_port source_portö
mipsdb_debug 51, ô3 4 5 6 7ö i.e. port 4 to 7 are mirrored to 3

To disable port mirroring:
mipsdb_debug 50

Note:
These commands do not survive a reboot. If the CXi reboots, you will have to reinitialize the mirroring.

Also, please note that when the mirroring is enabled, the port that is doing the mirroring cannot be used for any other purposes.

Update:
To mirror on an MXe
xmirror "2 1"
will mirror port 2 to port 1
