– 392 –
◆
The source port and destination port cannot be configured on the same
switch.
◆
A destination port can still send and receive switched traffic, and
participate in any Layer 2 protocols to which it has been assigned.
Example
The following example configures port 4 to receive mirrored RSPAN traffic:
Console(config)#rspan session 1 destination interface ethernet 1/2
Console(config)#
rspan remote vlan
Use this command to specify the RSPAN VLAN, switch role (source,
intermediate or destination), and the uplink ports. Use the
no
form to disable
the RSPAN on the specified VLAN.
