Command Usage
Only one destination port can be configured on the same switch per session,
but a destination port can be configured on more than one switch for the same
session.
Only ports can be configured as an RSPAN destination – static and dynamic
trunks are not allowed.
The source port and destination port cannot be configured on the same
switch.
A destination port can still send and receive switched traffic, and participate in
any Layer 2 protocols to which it has been assigned.
