Use this command to specify the destination port to monitor the mirrored traffic.
Use the no form to disable RSPAN on the specified port.
Traffic exiting the destination port is untagged.
The following example configures port 4 to receive mirrored RSPAN traffic:
rspan session session-id destination interface interface [tagged | untagged]
no rspan session session-id destination interface interface
session-id – A number identifying this RSPAN session. (Range: 1-2)
Only two mirror sessions are allowed, including both local and remote

then there is only one session available for RSPAN.
interface - ethernet unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-28/52)
tagged - Traffic exiting the destination port carries the RSPAN VLAN tag.
untagged - Traffic exiting the destination port is untagged.
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
Only 802.1Q trunk or hybrid (i.e., general use) ports can be configured as an
RSPAN destination port – access ports are not allowed (see
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.
