Configuring port mirroring 
Both bridge mode (Layer 2) and route mode (Layer 3) Ethernet ports support port mirroring. The term 
interface  in this chapter collectively refers to these two types of ports. You can use the  port link-mode  
command to set an Ethernet port to  operate in bridge or route mode (see  Layer 2—LAN Switching 
Configuration Guide ). 
Only the HP 5500 EI switch series supports configuring port mirroring on Layer 3 Ethernet interfaces.

egress port must belong to the remote probe VLAN while the reflector port may not. For more information 
about the source device, destination device, reflector port, egress port, and remote probe VLAN, see 
Port mirroring classification and implementation .  
 
 NOTE: 
The reflector port is used to enable local mirroring to support multiple monitor ports.

Figure 33 Layer 2 remote port mirroring implementation  
 
 
On the network shown in Figure 33,  
The source device does the following: 
1. Copies the packets received on the source po rt GigabitEthernet 1/0/1 to the egress port 
GigabitEthernet 1/0/2.  
2.  Forwards the packets to the intermediate device,  which then broadcasts the packets in the remote 
probe VLAN. 
3.  Transmits the packets to the destination device via the inte rmediate device.  
Then, the destination device does the following:...

Using the remote probe VLAN to enable local mirroring to 
support multiple monitor ports 
In typical local port mirroring configuration, you can configure only one monitor port in a local mirroring 
group. As a result, you cannot monitor traffic of a local device on multiple data monitoring devices. To 
do that, you can take advantage of the remote probe VLAN used in Layer 2 remote mirroring.  
In Layer 2 remote port mirroring, a remote probe VLAN is configured, and the mirrored packets are...
