◆ Configuration Guidelines
Take the following step to configure an RSPAN session:
1. Use the VLAN Static List (see “Configuring VLAN Groups” on page 138) to
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 uplink port
1
.
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 port
1
,
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
though RSPAN source and destination ports can still be configured. When
1. 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 “Adding Static Members to
VLANs” on page 140).
