Command Reference Guide – DHCP Chapter 1 DHCP Server Configuration Commands
1-14
Use the undo dhcp server static-bind command to cancel an IP-MAC address
binding.
By default, no IP address in an address pool is statically bound.
It should be noted that:
z An IP address can be statically bound to only one MAC address. A MAC address
can be bound with only one IP address statically.
z The IP address to be statically bound cannot be an interface IP address of the
device; otherwise the static binding does not take effect. The device of the bound
MAC address can also obtain another IP address.
Example
# Statically bind the IP address 10.1.1.1 to the MAC address 0000-e03f-0305.
(Assume that the interface address pool of VLAN interface 1 already exists and the IP
address belongs to the address pool.)
