■

Packets received on the destination port are those processed and forwarded by 
the switch.

■

The destination port to be configured cannot be a member port of an existing 
mirroring group; a fabric port (only the Switch 5500/5500G have this 
limitation), a member port of an aggregation group, an LACP enabled port, or 
an STP enabled port.

■

Only an existing static VLAN can be configured as the remote-probe VLAN. To 
remove a remote-probe VLAN, you need to restore it to a normal VLAN first. A 
remote port mirroring group becomes invalid if the corresponding 
remote-probe VLAN is removed.

In traffic mirroring, an ACL is applied to a port to identify traffics. Packets passing 
through the port and matching the ACL rules are mirrored to the destination port.

The departments of a company connect to each other through the Switch 5500:

■

PC 1 and PC 2 are connected to Switch through Ethernet 1/0/1. The IP address 
of PC 1 is 192.168.0.1.

■

Data monitoring device is connected to Ethernet 1/0/2 of Switch.

The administrator wants to monitor packets sent from PC 1 through the data 
monitoring device.

Use the traffic mirroring function to meet the requirement. Perform the following 
configurations on Switch:

■

Configure traffic mirroring on Ethernet 1/0/1. Mirror packets matching source 
IP address 192.168.0.1 to the destination port.

■

Configure Ethernet 1/0/2 as the destination port of traffic mirroring.
