FC-FC routing connectivity
This section describes tools you can use to troubleshoot Fibre Channel routing connectivity and performance.
Generating and routing an ECHO
The FC-FC Routing Service enables you to route the ECHO generated when an
fcPing
command is issued on a switch, providing
fcPing
capability between two devices in different fabrics across the FC router.
The
fcPing
command sends a Fibre Channel ELS ECHO request to a pair of ports. It performs a zone check between the source and
destination. In addition, two Fibre Channel Extended Link Service (ELS) requests are generated. The first ELS request is from the
domain controller to the source port identifier. The second ELS request is from the domain controller to the destination port identifiers.
The ELS ECHO request elicits an ELS ECHO response from a port identifier in the fabric and validates link connectivity.
Use the
fcPing
command to validate link connectivity to a single device or between a pair of devices.
ATTENTION
There are some devices that do not support the ELS ECHO request. In these cases, the device either does not respond to the
request or sends 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.
On the edge Fabric OS switch, make sure that the source and destination devices are properly configured in the LSAN zone before
entering the
fcPing
command. This command performs the following functions:
∙
Checks the zoning configuration for the two ports specified.
∙
Generates an ELS ECHO request to the source port specified and validates the response.
