Port Configuration

CLI References
• “RSPAN Mirroring Commands” on page 300
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 705), 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 752) 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 12 . 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 12 , 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.
12. 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 754).
