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
