Figure 69   Network diagram for remote port mirroring

 

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

■

Switch A, Switch B, and Switch C are Switch 5500s.

■

Department 1 is connected to Ethernet 1/0/1 of Switch A.

■

Department 2 is connected to Ethernet 1/0/2 of Switch A.

■

Ethernet 1/0/3 of Switch A connects to Ethernet 1/0/1 of Switch B.

■

Ethernet 1/0/2 of Switch B connects to Ethernet 1/0/1 of Switch C.

■

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

The administrator wants to monitor the packets sent from Department 1 and 2 
through the data monitoring device.

Use the remote port mirroring function to meet the requirement. Perform the 
following configurations:

■

Use Switch A as the source switch, Switch B as the intermediate switch, and 
Switch C as the destination switch.

■

On Switch A, create a remote source mirroring group, configure VLAN 10 as 
the remote-probe VLAN, ports Ethernet 1/0/1 and Ethernet 1/0/2 as the source 
ports, and port Ethernet 1/0/4 as the reflector port.

■

On Switch B, configure VLAN 10 as the remote-probe VLAN.

■

Configure Ethernet 1/0/3 of Switch A, Ethernet 1/0/1 and Ethernet 1/0/2 of 
Switch B, and Ethernet 1/0/1 of Switch C as Trunk ports, allowing packets of 
VLAN 10 to pass.

■

On Switch C, create a remote destination mirroring group, configure VLAN 10 
as the remote-probe VLAN, and configure Ethernet 1/0/2 connected with the 
data monitoring device as the destination port.
