ONFIGURATION

Perform the following configurations in system view.

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 monitoring port and multiple monitored ports.

Consider these issues when configuring port mirroring:

■

For intra-card mirroring, only one monitoring port can be configured for the 
mirroring groups in the same direction.

■

For cross-card mirroring, only one monitoring port (which is on another card) 
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 card:

■

For the mirroring (including incoming port mirroring and outgoing port 
mirroring) on the same GV48 or GP48 card, only one monitoring port is 
allowed.

■

For all mirroring groups configured in the system, only one monitoring port is 
allowed on the same GV48 or GP48 card.

By default, two port groups of the XP4 card are created. The member ports are 
port 0-1 and port 2-3 respectively. Consider these issues when configuring port 
mirroring:

■

The XP4 card does not support cross-group port mirroring, that is, the 
monitoring ports and monitored ports in the same port mirroring group can 
only be port 0 to 1 or port 2 to 3.

■

You can configure an inbound monitoring port and an outbound monitoring 
port in a port group respectively. There is only one monitoring port in other 
types of interface cards.

See the corresponding Command Manual for details of the commands.

Traffic statistics count packets of designated service traffic, that is, the packets 
match the defined ACL among those forwarded. You can view the information 
with the display qos-interface traffic-statistic command.
