 Note:
Perform the following two configuration tasks in system view.
2.2.2 Setting Port Mirroring
Port mirroring means duplicating data on the monitored port to the designated monitor
port, for purpose of data analysis and supervision. The switch supports many-to-one
mirroring, that is, you can duplicate packets from multiple ports to a monitoring port.
You can also specify the monitoring direction:
z Only inbound packets
z Only outbound packets
Please perform the following configurations in system view.
Table 2-3 Setting port mirroring
Operation Command
Set port mirroring
mirroring-group groupid { inbound | outbound }
mirroring-port-list &<1-8> mirrored-to monitor-port
Remove port mirroring
undo mirroring-group groupid
You can configure up to 20 mirroring groups, with each group including one monitoring
port and multiple monitored ports.
 Note:
z The monitoring port and the monitored ports must be on the same interface unit.
z For a non-48-port interface unit, only one mirroring group can be configured in one
direction. For example, you can only configure one mirroring group for the inbound
packets on one interface unit. Failure will be prompted if you configure a second.
The same restriction applies to outbound packets.
z For a 48-port interface unit, the monitoring port and the monitored port must all be at
the ports 1~24 or the ports 25~48, at which only one mirroring group can be
configured in one direction.
