Regardless of the device’s zoning configuration, the
fcPing
command sends the ELS frame to the
destination port. A destination device can take any one of the following actions:
•
Send an ELS Accept to the ELS request.
•
Send an ELS Reject to the ELS request.
•
Ignore the ELS request.
For details about the
fcPing
command, refer to the
Fabric OS Command Reference
.

Superping
Superping refers to the
fcPing --allpaths
command which is a diagnostic tool used to test all least
cost ISLs between a source and destination switch. When you run the command you are provided
with a list of all available least cost paths from a source domain to a destination device. Superping
isolates links with potential failures so that you can investigate these ISLs to determine the exact
links.
