Configuring Address Allocation Mode For Global Address Pool - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
An IP address is allocated to the VLANIF interface.
If there is no DHCP relay agent between the DHCP clients and S9300&S9300E, the
S9300&S9300E allocates IP addresses that are in the same network segment as the interface
address to the clients connected to this interface.
If the VLANIF interface is not configured with an IP address or no address pool is on the same
network segment as the interface address, the clients cannot go online.
If there is a DHCP relay agent between the DHCP clients and S9300&S9300E, the
S9300&S9300E parses the gateway address in the received DHCP packets forwarded by the
DHCP relay agent. If the gateway address does not match an entry in the address pool, the clients
cannot go online.
Step 5 Run:
dhcp select global
The DHCP function is enabled on the interface and the DHCP server allocates IP addresses to
clients by using the global address pool.

3.3.3 Configuring Address Allocation Mode for Global Address
Pool
According to the requirements of clients, you can select the static binding mode or the dynamic
allocation mode for address allocation, but the two modes cannot be enabled simultaneously for
the same IP address in the global address pool.
Context
Up to 256 address pools can be configured on the S9300&S9300E, including the global address
pools and interface address pools. The number of address pools of each type is not limited. To
use the dynamic allocation mode, you must specify the range of addresses to be allocated; to use
the static binding mode, only one address can be allocated to a client. The global address pool
attributes include the IP address range, IP address lease, IP addresses not to be automatically
allocated, and IP addresses to be statically bound to MAC addresses.
Perform the following steps on the DHCP server.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ip pool ip-pool-name
The global address pool view is displayed.
By default, no global address pool exists on the S9300&S9300E.
Step 3 Run:
network ip-address [ mask { mask | mask-length } ]
The range of IP addresses in the address pool is set.
