Using the show tech-support Command
Configuring Interoperability
The
interop
mode in Cisco MDS 9000 Family switches can be enabled disruptively or nondisruptively.
Brocade’s
msplmgmtdeactivate
command must explicitly be run prior to connecting from a Brocade
switch to either Cisco MDS 9000 Family switches or to McData switches. This command uses Brocade
proprietary frames to exchange platform information, which Cisco MDS 9000 Family switches and
McData switches do not understand. Rejecting these frames causes the common E ports to become
isolated.
Using the show tech-support Command
The
show tech-support
command is useful when collecting a large amount of information about your
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 will vary 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 or even 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 manually
scrolling. Use the
show terminal
command to view the configured the terminal size. After obtaining the
output of this command, remember to reset you terminal length as required
Tip
You can save the output of this command to a file by appending
>
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
The default output of the
show tech-support
command includes the output of the following commands:
•
show version
•
show environment
•
show module
•
show hardware
•
show running-config
•
show interface
•
show accounting log
•
show process
