Remote SPAN

The Remote SPAN (RSPAN) feature enables you to remotely monitor traffic for one or more SPAN
sources distributed in one or more source switches in a Fibre Channel fabric. The SPAN destination (SD)
port is used for remote monitoring in a destination switch. A destination switch is usually different from
the source switch(es) but is attached to the same Fibre Channel fabric. You can replicate and monitor
traffic in any remote Cisco MDS 9000 Family switch or director, just as you would monitor traffic in a
MDS source switch.
The RSPAN feature is nonintrusive and does not affect network traffic switching for any SPAN source
ports. Traffic captured on the remote switch is tunneled across a Fibre Channel fabric which has trunking
enabled on all switches in the path from the source switch to the destination switch. The Fibre Channel
tunnel is structured using trunked ISL (TE) ports. In addition to TE ports, the RSPAN feature uses two
other interface types:
