Configuring Remote Port Mirroring
■
MAC address learning is not supported on RSPAN uplink ports 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 the RSPAN uplink ports.
■
IEEE 802.1X – RSPAN and 802.1X are mutually exclusive functions. When
802.1X is enabled globally, RSPAN uplink ports cannot be configured, even
though RSPAN source and destination ports can still be configured. When
RSPAN uplink ports are enabled on the switch, 802.1X cannot be enabled
globally.
■
Port Security – If port security is enabled on any port, that port cannot be
set as an RSPAN uplink port, even though it can still be configured as an
RSPAN source or destination port. Also, when a port is configured as an
RSPAN uplink port, port security cannot be enabled on that port.
Parameters
These parameters are displayed:
◆ Session – A number identifying this RSPAN session. (Range: 1-3)
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 149 ).
◆ 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
