Deleting A Mirroring Session
The no form of the port-mirroring command can be used to delete a previously created mirroring session 
configuration between a mirrored port and a mirroring port.
To delete a mirroring session, enter the no port-mirroring command, followed by the port mirroring 
session ID number. For example:
-> no port-mirroring 6
In this example, port mirroring session 6 is deleted.
Note. The port mirroring session identifier must always be specified.
