Configuring Remote Port Mirroring
– 141 –
Parameters
These parameters are displayed:
Session – A number identifying this RSPAN session. (Range: 1)
Only one active session is allowed.
Operation Status – Indicates whether or not RSPAN is currently functioning.
Switch Role – Specifies the role this switch performs in mirroring traffic.
None – This switch will not participate in RSPAN.
Source - Specifies this device as the source of remotely mirrored traffic.
Intermediate - Specifies this device as an intermediate switch,
transparently passing mirrored traffic from one or more sources to one or
more destinations.
Destination - Specifies this device as a switch configured with a
destination port which is to receive mirrored traffic for this session.
Remote VLAN – The VLAN to which traffic mirrored from the source port will
be flooded. The VLAN specified in this field must first be reserved for the RSPAN
application using the VLAN > Static page (see page 157).
Uplink Port – A port on any switch participating in RSPAN through which
mirrored traffic is passed on to or received from the RSPAN VLAN.
Only one uplink port can be configured on a source switch, but there is no
limitation on the number of uplink ports
1
configured on an intermediate or
destination switch.
Only destination and uplink ports will be assigned by the switch as members of
the RSPAN VLAN. Ports cannot be manually assigned to an RSPAN VLAN
through the VLAN > Static page. Nor can GVRP dynamically add port members
to an RSPAN VLAN. Also, note that the VLAN > Static (Show) page will not
display any members for an RSPAN VLAN, but will only show configured RSPAN
VLAN identifiers.
Type – Specifies the traffic type to be mirrored remotely. (Options: Rx, Tx, Both)
Destination Port – Specifies the destination port
1
to monitor the traffic
mirrored from the source ports. 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. Also note that a destination port
can still send and receive switched traffic, and participate in any Layer 2
protocols to which it has been assigned.
Tag – Specifies whether or not the traffic exiting the destination port to the
monitoring device carries the RSPAN VLAN tag.
