Port Mirroring
Page 19-60
Setting Up Port Mirroring
You set up port mirroring when you add or modify a port through the
addvp
or
modvp
commands. The switch software senses the type of port you are configuring, so it will only
prompt you for port mirroring when configuring an Ethernet port. Follow the steps below to
set up port mirroring.
1. Start the
addvp
or
modvp
command for the virtual port that you want to mirror.
2. At the
Command
prompt enter
8=e
, press
<Enter>
and you will be prompted for the slot
and port number of the “mirroring” port (i.e., the port that can “see” all traffic for this
port):
Mirroring vport slot/port ? ( ) :
3. Enter the mirroring port’s slot, a slash (/), the port number, and then press
<Enter>
. The
port that you indicate here will be disabled and only capable of receiving duplicate traffic
from the mirrored port. If port mirroring is not supported on this port, then the following
prompt will display:
mirroring not supported on this port type
After entering the Mirroring slot and port number, the
addvp
or
modvp
screen of options
re-displays with the changes you entered. If you are done modifying or adding the port,
enter
save
at the
Command
prompt. If using the
addvp
command a message indicating that
you have successfully set up the port displays. Port mirroring takes place immediately, so
you could now connect a probe or network analyzer to the Mirroring port.
Disabling Port Mirroring
You can disable port mirroring through the
modvp
command. Follow these steps to disable
port mirroring.
1. Start the
modvp
command for the virtual port on which you want to disable port mirror-
ing.
2. At the
Command
prompt enter
8=d
, press
<Enter>
. The
modvp
screen re-displays. The
Mirrored Port Status
field should read
Disabled, available
.
