The network description is as follows:

■

Switch A is connected to the data monitoring device using Ethernet1/0/2.

■

Ethernet1/0/1, the Trunk port of Switch A, is connected to Ethernet 1/0/1, the 
Trunk port of Switch B.

■

Ethernet1/0/2, the Trunk port of Switch B, is connected to Ethernet 1/0/1, the 
Trunk port of Switch C.

■

Ethernet1/0/2, the port of Switch C, is connected to PC1.

The requirement is to monitor and analyze the packets sent to PC1 using the data 
monitoring device.

To meet the above requirement using the RSPAN function, perform the following 
configurations:

■

Define VLAN10 as remote-probe VLAN.

■

Configure Switch A to be the destination switch, Ethernet1/0/2, the port that 
connects the data monitoring device, to be the destination port of remote 
mirroring. Disable the STP function for Ethernet1/0/2.

■

Configure Switch B to be the intermediate switch.
