Giving Up Control to the Secondary MPX

The renounce command tells the primary MPX to give up control and become the secondary
MPX. It does this by issuing a request to the secondary MPX to take control. You must be
logged into the primary MPX to use this command. If you are logged into the secondary MPX,
use the takeover command, which is described in Gaining Control from the Primary MPX on
page 6-18.
♦ Warning ♦
The renounce command should only be used during
network down times since it could cause network inter-
ruptions.
To transfer control from primary MPX to the secondary MPX, enter
renounce
at the system prompt. The following prompt will display.
Confirm? (n):
Press y to transfer control to the secondary MPX or press n to cancel the command (the
default is n). If you enter y, the switch will reset after displaying the following message.
System going down immediately...
The switch will reboot and the original secondary MPX will be the primary once the switch
comes back up.

Setting the Load Suffix

The nisuf command sets the load suffix for the switch’s executable image files. (The factory
default suffix is img.)
♦ Warning ♦
The nisuf command should only be used when it is
necessary to have two versions of the software on the
switch at the same time and the user is directly
connected to the console for reboot.
You can change it by typing the nisuf command followed by the new suffix. For example, to
change the load suffix from img to bin, enter
nisuf bin
at the system prompt. The following message will then be displayed.
Changing load suffix from img to bin
You should create or load new image files with the new suffix as soon as possible because
the switch will not recognize the files with the old suffix as image files. See Chapter 5,
“Installing Switch Software,” and Chapter 7, “Managing Files,” for information on loading and
creating files.
