Function

The dhcp server sip-server command configures the SIP server IP address assigned to a DHCP client on an interface address pool.

The undo dhcp server sip-server command deletes the configured SIP server IP address assigned to a DHCP client on an interface address pool.

By default, the SIP server IP address assigned to a DHCP client on an interface address pool is not configured.

Usage Guidelines

Usage Scenario

This command applies to the DHCP server. To enable DHCP clients to normally access the Internet, the DHCP server needs to specify the SIP server IP address in the interface address pool when assigning IP addresses to the clients.

Prerequisites

The DHCP function has been enabled using the dhcp enable command in the system view.
IP addresses in the interface address pool have been configured using the ip address command.
The DHCP server function has been enabled on the interface using the dhcp select interface command.

Precautions

A maximum of two SIP server addresses can be configured in each address pool. The first assigned address functions as the primary address, and the other address functions as a secondary address.
Before specifying the IP address or name for a SIP server, ensure that the SIP server exists.
If you run this command repeatedly, the latest configuration overrides the previous ones.

Example

# Specify 10.1.1.1 as the IP address of the SIP server when addresses in the interface VLANIF100 address pool are assigned to clients.

<HUAWEI> system-view
[HUAWEI] dhcp enable
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] ip address 10.1.1.1 24 
[HUAWEI-Vlanif100] dhcp select interface
[HUAWEI-Vlanif100] dhcp server sip-server ip-address 10.1.1.1

# Specify 10.1.1.1 as the IP address of the SIP server when addresses in the interface GE0/0/1 address pool are assigned to clients.

<HUAWEI> system-view
[HUAWEI] dhcp enable
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] undo portswitch
[HUAWEI-GigabitEthernet0/0/1] ip address 10.1.1.1 24 
[HUAWEI-GigabitEthernet0/0/1] dhcp select interface
