Required
By default, static binding is not
configured
Note:
z The IP addresses statically bound in interface address pools and the interface IP
addresses must be in the same segment.
z There is no limit to the number of IP addresses statically bound in an interface
address pool, but the IP addresses statically bound in interface address pools and
the interface IP addresses must be in the same segment.
z 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.
z The IP address to be statically bound cannot be an interface IP address of the
DHCP server; otherwise the static binding does not take effect.
II. Configuring to assign IP addresses dynamically
As an interface-based address pool is created after the interface is assigned a valid
unicast IP address, the IP addresses contained in the address pool belong to the
network segment where the interface resides in and are available to the interface only.
So specifying the range of the IP addresses to be dynamically assigned is
unnecessary.
To avoid IP address conflicts, the IP addresses to be dynamically assigned to DHCP
clients are those not occupied by specific network devices (such as gateways and FTP
servers).
The lease time can differ with address pools. But that of the IP addresses of the same
address pool are the same. Lease time is not inherited, that is to say, the lease time of
a child address pool is not affected by the configuration of the parent address pool.
