client-identifier: Client ID of a static binding, a string of 4 to 160 characters in the format H-H-H..., each

H indicates 4 hex digits except the last H that indicates 2 or 4 hex digits. For example, aabb-cccc-dd is

a valid ID, while aabb-c-dddd and aabb-cc-dddd are both invalid.

mac-address: MAC address to which the IP address is statically bound.

Use the dhcp server static-bind command to statically bind an IP address of the current DHCP

interface address pool to a MAC address. When the client with the MAC address or ID requests an IP

address, the DHCP server will find the IP address from the binding in the interface address pool for the

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:

An IP address can be statically bound to only one MAC address or one client ID. A MAC address or

client ID can be bound with only one IP address statically.

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 bound MAC address can still obtain another IP address.
