show tech-support Command Chapter 50 Troubleshooting Send feedback to [email protected] 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, perform this task: 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 show tech-support Command The show tech-support command is useful when collecting a large amount of information about the switch for troubleshooting purposes. The output of this command can be provided to technical support representatives when reporting a problem. The show tech-support command displays the output of several show commands at once. The output from this command varies depending on your configuration. Use the show tech-support command in EXEC mode to display general information about the switch when reporting a problem. You can choose to have detailed information for each command. You can specify the output for a particular interface, module, or VSAN. Each command output is separated by line and the command precedes the output. Note Explicitly set the terminal length command to 0 (zero) to disable auto-scrolling and enable manual scrolling. Use the show terminal command to view the configured the terminal size. After obtaining the output of this command, remember to reset your terminal length as required. Tip You can save the output of this command to a file by appending > (left arrow) and the filename to the show tech-support command. If you save this file, verify you have sufficient space to do so-each of these files may take about 1.8 MB. However, you can zip this file using the gzip filename command. Copy the zipped file to the required location using the copy command and unzip the file using the gunzip command. 50-8 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide OL-16597-01
