Specifying the DHCP Server Operating Mode

By default, the mode in which the DHCP server operates is called safe mode.

When safe mode is enabled, the DHCP server cannot acknowledge the DHCP

client’s lease request until it receives a successful lease-commit acknowledgment

from the NetID Server Manager. Typically, you enable safe mode when you want

to ensure that the client receives only successful committed leases from the DHCP

server and the NetID Server Manager.

When safe mode is disabled, the DHCP server immediately returns a

lease-granted acknowledgment to the DHCP client in response to its lease request

without waiting for a successful lease-commit acknowledgment from the NetID

Server Manager. With safe mode disabled, the DHCP server can still assign IP

addresses to clients even if it loses communication with the NetID Server

Manager.

You can use the BCC or Site Manager to specify the DHCP server operating

mode.

Using the BCC

To enable or disable safe mode on the DHCP server, go to the global DHCP

prompt (for example,

box; ip; dhcp

) and enter:

safe-mode

<state>

state

is one of the following:

enabled

(default)

disabled

For example, the following command disables safe mode on the DHCP server.

dhcp#

safe-mode disabled

dhcp#
