Configure a SPAN Port

In this post I will create a SPAN port on my switch to send a copy of all sent and received traffic from port 10 to port 13.


switch1(config)#monitor session 1 source interface fastEthernet 0/10 both
switch1(config)#monitor session 1 destination interface fastEthernet 0/13
switch1(config)#end



I verify the configuration with a show command.

switch1#show monitor session 1
