Managing interface modules
7
Specifying an immediate shutdown
The management module takes approximately 16-20 seconds to shutdown all interface modules in
a device after a reload is issued. During this time, the interface module continues sending packets.
Enter the lp fast-powerdown command to immediately shut down all interface modules in a device
after a reload is issued.
Brocade(config)# lp fast-powerdown
Syntax: [no] lp fast-powerdown
If you do not enter this command, by default, the interface module continues to forward packets for
an extended time after the router is reloaded.
NOTE
You do not need to change the state of the interface module, or synchronize this shutdown with the
standby management module.
Changing the boot source
By default, the interface modules boot from the primary image located in flash memory. You can
change the boot source of one or all interface modules to one of the following sources:
• Management module
- auxiliary flash card in slot 1 or 2
- Primary or secondary image in the management module flash memory
• Interface module
- Secondary image in interface module flash memory
• TFTP server
You can also specify an interactive boot, which allows you to enter a separate command after the
interface module comes up. The command specifies the source from which one or all interface
modules should boot.
When changing the boot source for one or all interface modules, you can specify one of the
following:
• An immediate boot for one interface module from a specified source
• An automatic boot for one or all interface modules from a specified source starting with the
next software reload or system reset and each reload or reset after that
The CLI command for specifying an immediate boot for one interface module is the same as that
for specifying an automatic boot for one or all modules. The only difference is the CLI level from
which you execute the command. You must specify the command for an immediate boot in the
Privileged EXEC level and the command for an automatic boot in the global CONFIG level.
The following sections explain how to specify an immediate boot and an automatic boot.
Specifying an immediate boot
You can specify an immediate boot for one interface module from a specified source by entering
the lp boot system command in the Privileged EXEC level. The entered command will override the
default or configured boot source one time only.
