Two configuration solutions can be chosen for RSPAN: the first is without reflector port, and the other is with
reflector port. For the first one, only one fixed port can be connected to the intermediate switch. However, no
reflector port has to be configured. This maximizes the usage of witch ports. For the latter one, the port
connected to the intermediate switch is not fixed. Datagrams can be broadcasted in the RSPAN VLAN
through the loopback, which is much more flexible.
The normal mode configuration is show as below:
Solution 1:
Source switch:
Interface ethernet 1/1 is the source port for mirroring.
Interface ethernet 1/2 is the destination port which is connected to the intermediate switch.
RSPAN VLAN is 5.
Switch(config)#vlan 5
Switch(Config-Vlan5)#remote-span
Switch(Config-Vlan5)#exit
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)#switchport mode trunk
Switch(Config-If-Ethernet1/2)#exit
Switch(config)#monitor session 1 source interface ethernet1/1 rx
Switch(config)#monitor session 1 destination interface ethernet1/2
Switch(config)#monitor session 1 remote vlan 5
Intermediate switch:
Interface ethernet1/6 is the source port which is connected to the source switch.
Interface ethernet1/7 is the destination port which is connected to the intermediate switch. The native VLAN of
this port cannot be configured as RSPAN VLAN, or the mirrored data may not be carried by the destination
switch.
RSPAN VLAN is 5.
Switch(config)#vlan 5
Switch(Config-Vlan5)#remote-span
Switch(Config-Vlan5)#exit
Switch(config)#interface ethernet 1/6-7
Switch(Config-If-Port-Range)#switchport mode trunk
Switch(Config-If-Port-Range)#exit
Destination switch:
Interface ethernet1/9 is the source port, which is connected to the source switch.
Interface ethernet1/10 is the destination port which is connected to the monitor. This port is required to be
configured as an access port, and belong to the RSPAN VLAN.
RSPAN VLAN is 5.
