Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

For J Series Services routers and EX Series switches only. Set static bindings for DHCP clients. A static binding is a mapping between a fixed IP address and the client’s MAC address or client identifier.

Options

mac-address—The MAC address of the client. This is a hardware address that uniquely identifies a client on the network.

fixed-address address—Fixed IP address assigned to the client. Typically a client has one address assigned, but you can assign more.

host client-hostname—Hostname of the client requesting the DHCP server. The name can include the local domain name. Otherwise, the name is resolved based on the domain-name statement.

client-identifier (ascii client-id | hexadecimal client-id)—Used by the DHCP server to index the database of address bindings. The client identifier is an ASCII string or hexadecimal number and can include a type-value pair as specified in RFC 1700, Assigned Numbers. Either a client identifier or the client’s MAC address must be configured to uniquely identify the client on the network.

Required Privilege Level

system—To view this statement in the configuration.
