Configuration Files
Stand-alone switches and stacks store their parameter settings in
configuration files in their file systems. The devices use these files to
configure their parameter settings whenever they initialize their
management software, such as when you power on or reset the units.
The switches do not update the files automatically after you change a
parameter setting. Instead, you must update the files by performing save
commands in the management software. Once the parameter settings are
saved in the configuration files, they are retained even when the switches
or stacks are powered off.
You can upload the configuration files to a workstation or a TFTP server
for editing or to maintain a history of the configurations of the switches or
stacks.
Stand-alone
Switches
All of the switches in the AT-9400 Series come with a default boot
configuration called BOOT.CFG for stand-alone operation. You can use
this file or you can create another one. Each stand-alone switch must have
its own configuration file, but you can transfer the files if you want different
switches to have similar configurations.
AT-9400Ts
Stacks
When the AT-9424Ts, AT-9424Ts/XP, and AT-9448Ts/XP Switches are
installed as a stack, they store their parameter settings in a single boot
configuration file on the master switch. This one file contains the settings
for all of the switches in a stack.
The default name of this file is STACK.CFG. The switches do not come
with this file, but the master switch automatically creates it when you issue
the SAVE CONFIGURATION command for the first time after you create a
stack.
Selecting a
Configuration
File
So how do the switches know which file to use? The AT-9400 Switches
that can be used only as stand-alone units, such as the AT-9424T and
AT-9424T/POE Switches, always use the BOOT.CFG file or its
designated equivalent file.
The AT-9424Ts, AT-9424Ts/XP, and AT-9448Ts/XP Switches, which
support both stand-alone and stack operations, select a configuration file
based on their stack ID numbers. If the stack ID number is set to AUTO,
meaning automatic, the switch assumes that it is a stand-alone switch and
should use the BOOT.CFG file, or whatever stand-alone file you’ve
designated. This is the default setting for the switches.
If the stack ID is set to STATIC, the switch assumes that it is part of a
stack and that it should obtain its settings from the master switch. For
more information, refer to “Stack Configuration Files” on page 71.
