Enter interface configuration mode for the specified Ethernet interface selected by the port values. and so on, are not captured in the SPAN copy. The documentation set for this product strives to use bias-free language. A mirror or SPAN (switch port analyzer) port can be a very useful resource if used in the correct way. Clears the configuration of the specified SPAN session.
