DHCP address pool, class, or host configuration command mode.
These configuration parameters and other control information are carried in tagged data items that are stored in the options field of the DHCP message to network hosts. Several commonly-used options may also be configured using dedicated commands: domain-name, dns-server, netbios-name-server, netbios-node-type, and default-router.
The parameter format of a site-specific option must be either ascii or hex.
The “no” form of this command deletes a configured DHCP option.
This example shows how to configure DHCP option 19, which specifies whether the client should configure its IP layer for packet forwarding. In this case, IP forwarding is enabled with the 01 value:
System(rw-config)->ip dhcp pool localpool System(rw-config-dhcp-pool)->option 19 hex 01
This example shows how to configure DHCP option 72, which assigns one or more Web servers for DHCP clients:
System(rw-config)->ip dhcp pool localpool System(rw-config-dhcp-pool)->option 72 ip 168.24.3.252
