Currently, only one IP address in a global DHCP address pool can be statically bound to a MAC
address or a client ID.
Follow these steps to configure the static IP address allocation mode:

Required
By default, no IP
address is statically
bound.

address to which the IP
address is to be
statically bound

Configure the client ID
to which the IP address
is to be statically bound
static-bind client-identifier

One of these two
options is required
By default, no MAC
address or client ID to
which an IP address is
to be statically bound is
configured.
z
The static-bind ip-address command and the static-bind mac-address command or the static-bind
client-identifier command must be coupled.
z
In the same global DHCP address pool, if you configure the static-bind client-identifier command
after configuring the static-bind mac-address command, the new configuration overwrites the
previous one, and vice versa.
z
In the same global DHCP address pool, if the static-bind ip-address command, the static-bind
mac-address command, or the static-bind client-identifier is executed repeatedly, the new
configuration overwrites the previous one.
z
The IP address to be statically bound cannot be an interface IP address of the DHCP server;
otherwise static binding does not take effect.
z
A client can permanently use the statically-bound IP address that it has obtained. The IP address
is not limited by the lease time of the IP addresses in the address pool.
