How to configure RSPAN to detect the traffic of certain ports / vlans on Ruijie Switch?
Requirements:Copy the packets of the mirror port (source port) to the observation port (destination port) so that the complete packets can be obtained for network analysis.

Configurationsteps:
Source device:
switchA# configure terminal
switchA(config)# vlan 100
switchA(config-vlan)# remote-span --->set avlan for RSPAN
switchA(config-vlan)# exit
switchA(config)# monitor session 3remote-source --->setthis device as source device
switchA(config)# monitor session 3 source interfacegigabitethernet 0/1 both---->monitorboth input & output traffic from G0/1
switchA(config)# monitor session 3 destinationremote vlan 100 interface gigabitethernet 0/3 ---->send out the traffic copy from G0/3
Destination device:
switchB# configure
switchB(config)# interface gigabitethernet 0/1
Switch C(config-if)# switchport mode trunk
Switch C(config-if)#exi
switchB(config)# vlan 100
switchB(config-vlan)# remote-span --->set avlan for RSPAN
switchB(config-vlan)# exit
switchB(config)# monitor session 3remote-destination --->set thisdevice as destination device
switchB(config)# monitor session 3 destination remote vlan 100 interface gigabitethernet 0/2 ---->received the traffic copy from G0/2

Destination device(Switch C):
Switch C# configure

Verification:
Command: show monitor session 3
