•
rx—Monitor received traffic.
•
tx—Monitor sent traffic.
•
Specify the RSPAN session, the destination remote VLAN, and the
reflector port.
For session_number, enter the session number identified with this
RSPAN session.
For vlan-id, specify the RSPAN VLAN to carry the monitored traffic
to the destination port. (See the
