{ interface interface-id | vlan vlan-id } [ , |
- ] [ both | rx | tx ]
Step 4
• For session_number , the range is 1 to 66.
Example:
Switch(config)# monitor session 1
• For interface-id , specify the source port to monitor. Valid interfaces
include physical interfaces and port-channel logical interfaces
(

Monitors sent traffic.
You can use the monitor session session_number source
command multiple times to configure multiple source
ports.
Note
Specifies the SPAN session and the destination port (monitoring port). monitor session session_number
