Figure 8-2 RSPAN Application Sample

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 1/0/1 is the source port for mirroring.

Interface ethernet 1/0/2 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 1/0/2

Switch(Config-If-Ethernet1/0/2)#switchport mode trunk

Switch(Config-If-Ethernet1/0/2)#exit

Switch(config)#monitor session 1 source interface ethernet1/0/1 rx

Switch(config)#monitor session 1 destination interface ethernet1/0/2

Switch(config)#monitor session 1 remote vlan 5

Intermediate switch:

Interface ethernet1/0/6 is the source port which is connected to the source switch.

Interface ethernet1/0/7 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

Source Switch

Intermediate Switch

Destination Switch
