Chapter 52 Monitoring Network Traffic Using SPAN
Remote SPAN
Note
The default value for all the SPAN sessions is 15. The span drop-threshold can be issued only if
the sessions are inactive.

Remote SPAN
Note
Remote SPAN is not supported on the Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco
Fabric Switch for IBM BladeSystem.
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
Cisco MDS source switch.
The RSPAN feature is nonintrusive and does not affect network traffic switching for those 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 (see
Figure 52-8
):
•
SD ports—A passive port from which remote SPAN traffic can be obtained by the FC analyzer.
•
ST ports—A SPAN tunnel (ST) port is an entry point port in the source switch for the RSPAN Fibre
Channel tunnel. ST ports are special RSPAN ports and cannot be used for normal Fibre Channel
traffic.
