Configuring RSPAN on the destination switch
Configuration example
■ Switch A is connected to the data detect device using GigabitEthernet1/0/2.
■ GigabitEthernet1/0/1, the Trunk port of Switch A, is connected to GigabitEthernet
1/0/1, the Trunk port of Switch B.
■ GigabitEthernet1/0/2, the Trunk port of Switch B, is connected to GigabitEthernet
1/0/1, the Trunk port of Switch C.
■ GigabitEthernet1/0/2, the port of Switch C, is connected to PC1.
The purpose is to monitor and analyze the packets sent to PC1 using the data detect
device.
