Configuring Remote Port Mirroring

– 207 –

session is allowed, either local or remote. Also, note that the source

port and destination port cannot be configured on the same switch.

MAC address learning is not supported on RSPAN uplink ports

(

Figure 90

) when RSPAN is enabled on the switch. Therefore, even

if spanning tree is enabled after RSPAN has been configured, MAC

address learning will still not be re-started on RSPAN uplink ports.

P

ARAMETERS

These parameters are displayed:

Session Number – A number identifying this RSPAN session. Only one

mirror session is allowed, including both local and remote mirroring. If

local mirroring is enabled (see

page 204

), then no session can be

configured for RSPAN.

Mode – Enables or disabled RSPAN.

Type – Specifies the role this switch performs in mirroring traffic.

Mirror – Local port mirroring (see

"Configuring Local Port Mirroring"

on page 204

).

Source - Specifies this device as the source of remotely mirrored

traffic. Source port(s), reflector port, and intermediate port(s) are

located on this switch.

Intermediate - Specifies this device as an intermediate switch,

transparently passing mirrored traffic from one or more sources to

one or more destinations. Intermediate ports are located on this

switch.

Destination - Specifies this device as a switch which is to receive

mirrored traffic for this session. Intermediate port(s) and

destination port(s) are located on this switch.

VLAN ID – The VLAN to which traffic mirrored from the source port will

be flooded.
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 Membership configuration page. Nor

can GVRP dynamically add port members to an RSPAN VLAN.

Reflector Port – A port on a source switch through which mirrored

traffic is passed on to the RSPAN VLAN.
The reflector port only applies to Source switch type.
MAC Table learning and STP must be disabled on the reflector port.

Port – Port Identifier.

Source – A port from which traffic is mirrored onto the RSPAN VLAN.

(Options: Disabled, Both, Rx only, Tx only)
