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.
