show tech-support Command
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:
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.
Command Purpose
Step 1
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.
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
Verifies reachability of the destination
switch by checking its end-to-end
connectivity.
