Specifying the Bootstrap
Programs for the Switch
You can specify two bootstrap programs for both active and standby SRPCs of the
switch, with one used as the primary program and the other as the backup
program. You can use the following command to specify the bootstrap programs
for the switch:
If the switch fails to boot up through the specified bootstrap program, it retries to
boot up by using a program in the flash memory or the CF card. If it fails again,
the switch fails to start.
The switch select one application program as bootstrap program from Flash or CF
card according to the different values of flag BootDev. The detail is as follows:
■ There are two primary bootstrap programs: one is in the Flash card (assume it is
A); the other is in the CF card (assume it is B).
■ There are two backup programs too: one is in the Flash card (assume it is C);
the other is in the CF card (assume it is D).
■ There is one flag BootDev.
You can view or modify the names of the bootstrap programs and enable
equipment flag BootDev.
