Table 2-4 Configure to assign IP addresses by static binding
Enter system view
Create a DHCP address pool and
enter DHCP address pool view
Configure an IP address to be
statically bound
Bind an IP
address to
the MAC
address of
a DHCP
client or a
client
statically
Note:
The static-bind ip-address command and the static-bind mac-address
command or the static-bind client-identifier command must be coupled.
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.
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.
The IP address to be statically bound cannot be an interface IP address of the
DHCP server; otherwise static binding does not take effect.
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.
