Figure 39: Configuring Remote Port Mirroring
Command Usage
◆ Traffic can be mirrored from one or more source ports to a destination port on
the same switch (local port mirroring as described in “Configuring
Local Port Mirroring” on page 126), or from one or more source ports on
remote switches to a destination port on this switch (remote port mirroring as
described in this section).
◆ Configuration Guidelines
Take the following step to configure an RSPAN session:
1. Use the VLAN Static List (see “Configuring VLAN Groups” on page 170) 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
2
. 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
2
, 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.
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 “Adding Static Members to VLANs” on
page 173).
