Configuration mode


service {

			authoritative state
		}
	}
}

Use this command to set the DHCP server as the authoritative server.

Setting the server as authoritative sets the server as a master server and allows it to protect itself from rogue DHCP servers or misconfigured DHCP clients. If the server is authoritative, it sends a DHCPNAK to a misconfigured client; otherwise, the client cannot update its IP address until after the old lease expires.

Use the set form of this command to enable or disable the authoritative state for the DHCP server.

Use the delete form of this command to restore the default authoritative state, which is not authoritative.

Use the show form of this command to display whether the DHCP server is authoritative.
