Configuration Guidelines
Take the following step to configure an RSPAN session:
1.
Use the VLAN Static List (see
reserve a VLAN for use by RSPAN (marking the "Remote VLAN" field on this
page. (Default VLAN 1 is prohibited.)
2.
Set up the source switch on the RSPAN configuration page by specifying
the mirror session, the switch's role (Source), the RSPAN VLAN, and the
2
uplink port . Then specify the source port(s), and the traffic type to monitor
(Rx, Tx or Both).
3.
Set up all intermediate switches on the RSPAN configuration page, entering
the mirror session, the switch's role (Intermediate), the RSPAN VLAN, and
the uplink port(s).
4.
Set up the destination switch on the RSPAN configuration page by
specifying the mirror session, the switch's role (Destination), the destination
2
port , whether or not the traffic exiting this port will be tagged or
untagged, and the RSPAN VLAN. Then specify each uplink port where the
mirrored traffic is being received.

RSPAN Limitations
The following limitations apply to the use of RSPAN on this switch:
■ RSPAN Ports – Only ports can be configured as an RSPAN source,
destination, or uplink; static and dynamic trunks are not allowed. A port can
only be configured as one type of RSPAN interface – source, destination, or
uplink. Also, note that the source port and destination port cannot be
configured on the same switch.
Local/Remote Mirror – The destination of a local mirror session (created on
■
the Interface > Port > Mirror page) cannot be used as the destination for
RSPAN traffic.
Spanning Tree – If the spanning tree is disabled, BPDUs will not be flooded
■
onto the RSPAN VLAN.
■ 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
2. Only 802.1Q trunk or hybrid (i.e., general use) ports can be configured as an RSPAN uplink or
destination ports – access ports are not allowed (see
page 169).
