2. Regardless of the device's zoning, the fcPing command sends the ELS frame to the destination port. A
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.
There are some devices that do not support the ELS ECHO request. In these cases, the device will either
not respond to the request or send an ELS reject. When a device does not respond to the ELS request,
further debugging is required; however, do not assume that the device is not connected to the Fibre
Channel.
Following is sample output from the fcPing command in which one device accepts the request and
another device rejects the request:
