Once logged into the switch (and if necessary in enable mode using `enable admin`), use the `show mirror` command to display any current port mirroring configuration:
switch:4#show mirror Command: show mirror Current Settings Mirror Status: Disabled Target Port : X Mirrored Port RX: TX: switch:4#
To actually configure port mirroring, use the `config mirror` command which takes various options including the port to mirror too, which port(s) to mirror (the "source" port(s)), and whether to mirror rx (received packets), tx (transmitted packets), or both. A basic example of the command format is as follows:
switch:4#config mirror port 4 add source ports 12 both Command: config mirror port 4 add source ports 12 both Success. switch:4#show mirror Command: show mirror Current Settings Mirror Status: Disabled Target Port : 4 Mirrored Port RX: 12 TX: 12 switch:4#
and then enable the mirroring:
switch:4#enable mirror Command: enable mirror Success. switch:4#
And that should just about do it.
