atswitchMirrorState

if the state of Mirroring is enabled by selecting one of the
first three values , then the Mirroring explained above works.
If disabled, port operation works normally. No Traffic
gets routed from MirroringSourcePort to Destination Mirrored Port. 
Mirroring of both transmit and receive activity can only be
done if the port is half duplex. Choose both only if you know
the port will be run in half duplex mode.
