Optional) Configuring The Dns Service Of The Vlanif Interface Address Pool - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
The interface address pool is actually the network segment to which the interface belongs, and
such an interface address pool takes effect only on this interface.
Step 6 Run:
dhcp server lease { day day [ hour hour [ minute minute ] ] | unlimited }
The lease of IP addresses is set.
By default, the IP address lease is one day.
Step 7 (Optional) Run:
dhcp server excluded-ip-address start-ip-address [ end-ip-address ]
The IP addresses that cannot be automatically allocated in the DHCP address pool are configured.
Some IP addresses are reserved for other services, for example, the IP address of the DNS server
cannot be allocated to clients. You can run the dhcp server excluded-ip-address command to
exclude these IP addresses. If you run the dhcp server excluded-ip-address command multiple
times, you can set multiple IP address ranges that cannot be automatically allocated in the DHCP
address pool.
Step 8 (Optional) Run:
dhcp server static-bind ip-address ip-address mac-address mac-address
An IP address in the address pool is bound to a MAC address.
When a client requires a fixed IP address, bind an idle IP address in the address pool to the MAC
address of the client.

3.4.3 (Optional) Configuring the DNS Service of the VLANIF
Interface Address Pool
Each client has a domain name. To enable DHCP clients to communicate by using their domain
names and prevent IP address conflicts, the DHCP server needs to specify domain names for
these clients when allocating IP addresses to them.
Context
On the DHCP server, the dhcp server domain-name command specifies a domain name for
each interface address pool. When allocating IP addresses to clients, the DHCP server also sends
the domain names to the clients. During domain name resolution, users only need to enter a part
of the domain name, and then the system uses a complete domain name for resolution.
Perform the following steps on the DHCP server.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif vlan-id
