Configuring Remote Port Mirroring
– 210 –
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 91) 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.
PARAMETERS
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 207), 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 207).
■
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.
