Port Configuration
– 160 –
â–
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)
Only one mirror session is allowed, including both local and remote
mirroring. If local mirroring is enabled (see page 156), then no session
can be configured for RSPAN.
◆ Operation Status – Indicates whether or not RSPAN is currently
functioning.
◆ Switch Role – Specifies the role this switch performs in mirroring
traffic.
â–
None – This switch will not participate in RSPAN.
â–
Source - Specifies this device as the source of remotely mirrored
traffic.
â–
Intermediate - Specifies this device as an intermediate switch,
transparently passing mirrored traffic from one or more sources to
one or more destinations.
â–
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 198).
◆ 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)
