Explicit Paths

You can specify an explicit path through the Cisco MDS Fibre Channel fabric (source-based routing),
using the explicit-path option. For example, if you have multiple paths to a tunnel destination, you can
use this option to specify the FC tunnel to always take one path to the destination switch. The software
then uses this specified path even if other paths are available.
This option is especially useful if you prefer to direct the traffic through a certain path although other
paths are available. In an RSPAN situation, you can specify the explicit path so the RSPAN traffic does
not interfere with the existing user traffic. You can create any number of explicit paths in a switch (see
