What is MAC-IP Binding and how to configure it?

MAC-IP binding allows us to reserve static IP assignment for a client. The maximum supported entries are 32 and this feature is applicable for Local DHCP Scope only.

 

  • Helps reserve IP address for specific client.
  • Reserving an IP address allows us to create policies in the firewall configuration, to prioritize the traffic.

Environment : This article applies to Instant Access Point running Instant Firmware version 6.4.0.2_4.1.0.0 and later.

  • MAC-IP dhcp can be applied only for Local DHCP Scope
  • Maximum support entries are 32.
  • Once static reservation is configured, need to ensure it's reflected under "DHCP HOST" under respective Local DHCP pool when executing "show dhcps"
  • The static reservation should also be reflected under "show dhcp-allocation" for the corresponding Local DHCP pool.
