-> dhcp list definedoptions
This command lists all available options starting with the string “name”.
-> dhcp list definedoptions <name>
To list the lease time, enter:
-> dhcp list lease
Example:
This command lists the subnet 192.168.254.0 including any options set specifically for
that subnet:
-> dhcp list 192.168.254.0
Managing BootP
Administrators can enable and disable BootP and specify the BootP server. BootP
can be enabled at the subnetwork and at the client lease level.
NOTE:
By default, the DHCP server does not satisfy BootP requests unless the administrator
has explicitly enabled BootP (at the subnetwork or lease level).
About BootP and DHCP
BootP and DHCP provide services that are very similar. However, as an older service,
BootP offers only a subset of the services provided by DHCP.
The main difference between BootP and DHCP is that the client lease expiration for a
BootP client is always infinite.
NOTE:
Remember, when BootP is enabled, the client assumes that the lease is infinite.
Enable/Disable BootP
To allow BootP request processing for a particular client/subnet, use the command:
-> dhcp bootp allow <net> | <ipaddr>
To disallow BootP request processing for a particular client/subnet, enter:
-> dhcp bootp disallow <net> | <ipaddr>
