•Indicates commands that we will review because they are the commands used to ascertain the source(s) of the
most common problems Brocade support encounters. More information on all other commands can be found in
the supportShow Reference Guide. These commands, including the ones for Brocade use only, are all executed at
approximately the same time to permit more accurate investigation by development engineers if needed.
1.There are more than 100 Brocade Fabric OS commands. Instead of asking the customer to issue every single
command, Brocade engineers took the most useful commands and combined them into the supportshow
super command.
2.The supportshow command prints the switch information for debugging purposes. Not all versions of
Brocade Fabric OS include headers to identify and distinguish command outputs, so we must be able to identify
relevant outputs. Version 3.0 and above includes header information.
3.Some commands are used only by Brocade software developers. These command generate information about
the registers to the component level. We are only interested in the Field Replaceable Unit (FRU) level.
4.One of the main objectives of this module for you is to learn how to collect and interpret supportshow data
using Telnet commands outputs.
5.There is a supportshow Reference Guide available.
We will use the supportshow Reference Guide to briefly discuss each output shown above with an asterisk (*).
