static-binding (dhcpv4-pool-config)

Configures static IP address information for a particular device. Static address binding is executed on the device‘s hostname, client identifier, or MAC address. Static bindings allow the configuration of client parameters, such as DHCP server, DNS server, default routers, fixed IP address, etc.

A static address binding is a collection of configuration parameters, including an IP address, associated with, or bound to, a DHCP client. Bindings are managed by DHCP servers. DHCP bindings automatically map a device MAC address to an IP address using a pool of DHCP supplied addresses. Static bindings assign IP addresses without creating numerous host pools with manual bindings. Static host bindings use a text file the DHCP server reads. It eliminates the need for a lengthy configuration file and reduces the space required to maintain address pools.

Supported on the following devices:

Syntax

static-binding [client-identifier <CLIENT>|hardware-address <MAC>]

Parameters

static-binding [client-identifier <CLIENT>|hardware-address <MAC>]

client-identifier <CLIENT>

Enables a static binding configuration for a client based on its client identifier (as provided by DHCP option 61 and its key value)

  • <CLIENT> – Specify the client identifier (DHCP option 61).

hardware-address <MAC>

Enables a static binding configuration for a client based on its MAC address

  • <MAC> – Specify the MAC address of the client.
