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 .
Example of one device that accepts the request and another device that rejects the request

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.
