Verifying Switch Connectivity
You can verify connectivity to a destination switch.
The FC ID variable used in this procedure is the domain controller address; it is not a duplication of the
Note
domain ID.
To verify connectivity to a destination switch, follow these steps:
Command
Step 1
switch# show fcdomain domain-list vsan 200
Number of domains: 7
Domain ID
---------
0x01(1)
0x02(2)
0x6f(111)
0xda(218)
0x06(6)
0x04(4)
0x6a(106)
Step 2
switch# fcping fcid 0xFFFCDA vsan 200
28 bytes from 0xFFFCDA time = 298 usec
28 bytes from 0xFFFCDA time = 260 usec
28 bytes from 0xFFFCDA time = 298 usec
28 bytes from 0xFFFCDA time = 294 usec
28 bytes from 0xFFFCDA time = 292 usec
5 frames sent, 5 frames received, 0 timeouts
Round-trip min/avg/max = 260/288/298 usec
Configuring a Fabric Analyzer
Fibre Channel protocol analyzers capture, decode, and analyze frames and ordered sets on a link.
Existing Fibre Channel analyzers can capture traffic at wire rate speed. They are expensive and support
limited frame decoding. Also, to snoop traffic, the existing analyzers disrupt the traffic on the link while
the analyzer is inserted into the link.
Cisco has brought protocol analysis within a storage network to a new level with the Cisco Fabric
Analyzer. You can capture Fibre Channel control traffic from a switch and decode it without having to
disrupt any connectivity, and without having to be local to the point of analysis.
The Cisco Fibre Channel protocol analyzer is based on two popular public-domain software
applications:
•
•
The Cisco Fabric Analyzer is useful in capturing and decoding control traffic, not data traffic. It is
Note
suitable for control path captures, and is not intended for high-speed data path captures.

Troubleshooting Your Fabric
Purpose
Displays the destination switch's domain ID.
To obtain the domain controller address,
concatenate the domain ID with FFFC. For
example, if the domain ID is 0xda(218), the
concatenated ID is 0xfffcda.
Verifies reachability of the destination
switch by checking its end-to-end
connectivity.
