FC-FC routing connectivity 2 In the following example, superping is invoked using the fcPing --allpaths command to destination domain 165. The following example 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.

NOTE Superping provides an indication if all ISLs are covered. If all the ISLs are not covered, you can increase the coverage count and maximum retries to transmit, so that complete coverage of all ISLs is achieved. Consider the following example in which a few errors are recorded on ISLs 3/205-->2/25, 3/204-->2/27, 2/42-->101/3, and 2/1-->101/8. But a maximum of 100 percentage errors are recorded on internal port 0/284 on domain 2, which is the potential faulty link.
