To reference the explicit path, follow these steps:

switchS# config t

switchS(config)# interface fc-tunnel 100

switchS(config)# explicit-path Path1

This configuration explicitly specifies Path 1 to be used for the RSPAN traffic. Refer to RFC 3209 for

further details on explicit paths and source based routing.

Monitoring RSPAN Traffic

Once the session is configured, other SPAN sources for this session can also be configured as required.

Figure 43-15

fc1/1 is used to capture traffic in both ingress and egress directions.

Figure 43-15

To use this setup, the analyzer should have the capability of distinguishing ingress and egress traffic for

all captured frames.

RSPAN can be combined with the local SPAN feature so SD ports forward local SPAN traffic along with

remote SPAN traffic. Various SPAN source and tunnel scenarios are described in this section.
