By default, no DHCP address pool is created.
3 Configure the range of a DHCP address pool
a Configure the static binding address allocated to the client
Some special clients (e.g., WWW server) need to be bound with fixed IP addresses,
that is, to bind a certain client MAC address with a certain IP address. When the
client with this MAC address applies for a DHCP address, the server will find the
corresponding fixed IP address according to the client MAC address, and allocate it
for the client. You can assume that a statically binding address is a special DHCP
address pool that contains only one address.
Perform the following configurations in DHCP address pool view.
Table 368 Configure the statically binding IP address and MAC address
By default, no binding of DHCP client IP address and MAC address is configured.
For the binding client MAC address, the default type is
ethernet .
The command
static-bind ip-address
must be used together with the
static-bind mac-address
command. None of them have the superposition
function, that is, the latest configuration will replace the previous one.
The command
network
and the commands
static-bind ip-address
and
static-bind mac-address
are conflicting. In other words, a DHCP address pool
can be used either to configure statically binding addresses or the dynamic
addresses, but not both.
b Configure the dynamic IP addresses allocated to clients
For the addresses dynamically allocated to the clients (including the permanent
dynamic addresses and those dynamic addresses with a limited lease period), it is
necessary to configure the range of the address pool. Only one address segment
can be configured in one address pool, and the mask can be used to set the
address range.
Perform the following configurations in DHCP address pool view.
Table 369 Configure the range of the dynamically allocated IP addresses
By default, no DHCP address pool is configured, that is, there are no allocable
addresses.
