Configuration Guidelines
Take the following step to configure an RSPAN session:
1.
Use the VLAN Static List (see "Configuring VLAN Groups" on
page 168 ) 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. 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, 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 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
