Solution 2:  
Source switch: 
Interface ethernet 1/1 is the source port. 
Interface ethernet 1/2 is the TRUNK port, which is connected to the intermediate switch. The 
native VLAN should not be a RSPAN VLAN. 
Interface  Ethernet  1/3 is  a  reflector port. The  reflector port  belongs the  RSPAN  VLAN, it  is 
access port or TRUNK port of the RSPAN VLAN. 
RSPAN VLAN is 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 destination switch. The 
native VLAN of the port should not be configured as RSPAN VLAN, or the mirrored data may 
not be carried by the destination switch. 
RSPAN VLAN is 5.
