5.1.5.1.21 DHCPSERVER ADD FIXEDHOST
Syntax DHCPSERVER ADD FIXEDHOST <name> <ipaddress> <macaddress>
Description This command creates a new fixed host mapping in the DHCP server. This allows you to
configure the DHCP server to assign a specific IP address to a specific DHCP client
based on the client’s MAC address. If a DHCPDISCOVER or DHCPREQUEST is
received from a DHCP client with a matching MAC address, it will have the specified
fixed IP address assigned to it. You must also create a suitable DHCP subnet definition in
order for fixed host mapping to work.
Note: If you create a fixed host mapping with an IP address that is already present inside a configured,
dynamic IP range, the fixed host IP address will override the address in the dynamic range.
Options The following table gives the range of values for each option that can be specified with
this command and a default value (if applicable).
