1.2.9 Configuring Port Mirroring

Port mirroring duplicates data on the monitored port to the designated monitor port, for
purpose of data analysis and supervision. The switch supports multiple-to-one
mirroring, that is, you can duplicate packets from multiple ports to a monitor port.
You can also specify the monitoring direction:
Only inbound packets
Only outbound packets
Perform the following configurations in system view.
Configure port mirroring
Remove port mirroring setting
You can implement port mirroring configuration by setting mirroring groups at the port.
Up to 20 mirroring groups can be configured at a port, with each group including one
monitor port and multiple monitored ports.
Note:
The S9500 series support cross-board mirroring, that is, the monitoring and monitored
ports can be at different boards.
Note the following when configuring port mirroring:
For intra-board mirroring, only one monitor port can be configured for the mirroring
groups in the same direction.
For cross-board mirroring, only one monitor port (which is on another board) can
be configured for the mirroring groups in the same direction.
You can only configure eight monitored ports for all the mirroring groups in
transmit group.
One port can act as mirroring port and mirrored port at the same time for different
mirroring group.
More issues for the GV48 or GP48 board:
For the mirroring (including incoming port mirroring and outgoing port mirroring) on
the same GV48 or GP48 board, only one monitor port is allowed.
For all mirroring groups configured in the system, only one monitor port is allowed
on the same GV48 or GP48 board.
To do...
1-22
Use the command...
mirroring-group groupid { inbound |
outbound } mirroring-port-list mirrored-to
monitor-port
undo mirroring-group groupid
