FC-FC routing connectivity

The number of actual paths covered when using the superping tool depends on two other
parameters that you can optionally specify. When you issue the fcPing --allpaths command
without any other options, superping covers all ISLs in the routes between source to destination.
FIGURE 1
In the example below, superping is invoked using the fcPing --allpaths command to destination
domain 165. The example below displays each hop as (Domain1/Index1-> Domain2/Index2)
format. To reach destination domain 165 from source domain 3 there are 2 unique end-to-end
paths. In the first path, the frame traverses from egress port index 205 on source domain 3 to
ingress port index 25 on domain 207. On domain 207 the frame traverses from egress port index
42 to ingress port index 3 in domain 101. On domain 101 the frame goes from egress port index
16 to ingress port index 99 on domain 165.

Superping can isolate links with failures so that you can further investigate these ISLs to determine
the exact links giving the errors.
