So, I have built a tool that allows users to configure SPAN sessions on a Cisco switch. I'm currently trying to get the application to work for the Nexus series but there is one command I'm not sure of.

When you are removing a port from a SPAN session, you would use the following example command no monitor session 1 interface fastethernet 0/2, but I'm unsure if that command works on the Nexus series. I have looked through the config guides, and all they show is how to add ports, but they don't show how to remove ports from a SPAN session. Unfortunately, I don't have access to that type of switch yet, and I would like to know the command before I test my application on the switch.

Does anyone know if this the right command for removing ports from a session, or is there different command used on the Nexus series?

Cisco is pretty consistent with using the no in front of a command to remove or disable the command. Cisco provides many documents, such as Cisco Nexus 5000 Series NX-OS Software Configuration Guide which detail how to configure SPAN, including removing it:

enter image description here

You add a source port to a SPAN session with:

switch(config-monitor)# source interface <type> <slot> / <port> [ rx | tx | both ]

You remove a source port from a SPAN session with:

switch(config-monitor)# no source interface <type> <slot> / <port>
