Note The FC ID variable used in this procedure is the domain controller address; it is not a duplication of the domain ID. To verify connectivity to a destination switch, follow these steps: Step 1 Step 2 Command Purpose switch# show fcdomain domain-list vsan 200 Number of domains: 7 Domain ID WWN 0x01(1) 20:c8:00:05:30:00:59:df [Principal] 0x02(2) 20:c8:00:0b:5f:d5:9f:c1 0x6f(111) 20:c8:00:05:30:00:60:df 0xda(218) 20:c8:00:05:30:00:87:9f [Local] 0x06(6) 20:c8:00:0b:46:79:f2:41 0x04(4) 20:c8:00:05:30:00:86:5f 0x6a(106) 20:c8:00:05:30:00:f8:e3 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. 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 Verifies reachability of the destination switch by checking its end-to-end connectivity. 5 frames sent, 5 frames received, 0 timeouts Round-trip min/avg/max = 260/288/298 usec Cisco 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. The Cisco MDS 9000 Family switches support protocol analysis within a storage network 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 Fabric Analyzer is based on two popular public-domain software applications: • libpcap-See http://www.tcpdump.org. • Ethereal-See http://www.wireshark.org. Note The Cisco Fabric Analyzer is useful in capturing and decoding control traffic, not data traffic. It is suitable for control path captures, and is not intended for high-speed data path captures.
