Boot Flags
The boot flags allow you to alter how the switch boots up. The hexadecimal values of the flags and
their actions are listed in Tab le 8. You can aggregate flags to perform multiple functions by summing
the hex values for the commands.
For example, the following command aggregates the flags 0x40 + 0x2000 + 0x40000 and instructs the
switch to use DHCP to get boot parameters, disable the ShoreTel shell, and set network speed and
duplex mode to 100 Mb HD:
0x42040
