Use the undo dhcp relay server-groupcommand to remove a DHCP server from a DHCP server group, if no ip ip-addressis specified, all servers in the DHCP server group and the server group itself will be removed.

By default, no DHCP server is specified for a DHCP server group.

Note that:

■The IP address of any DHCP server and any interface’s IP address of the DHCP relay agent cannot be in the same network segment. Otherwise, the client may fail to obtain an IP address.

■If a server group has been correlated to multiple interfaces, you need to cancel these correlations before removing the server group.

Related command: display dhcp relay server-group.

Example # Specify DHCP server 1.1.1.1 for DHCP server group 1 on the relay agent.

[Sysname] dhcp relay server-group 1 ip 1.1.1.1

dhcp relay server-select

Syntax dhcp relay server-select group-id

undo dhcp relay server-select

View Interface view

Parameter group-id: Specifies a DHCP group number to be correlated, in the range of 0 to

19.The specified group must be an existing group containing at least a DHCP server.

Description Use the dhcp relay server-selectcommand to correlate specified interface(s) to a specified DHCP server group.

Use the undo dhcp relay server-selectcommand to remove a configured correlation.

By default, no DHCP server group is correlated with an interface on the relay agent.

Note that an interface on the relay agent can only be correlated to one DHCP server group, and a newly configured correlation overwrites the previous one. If the server group in the new correlation does not exist, the new configuration will not work. The interface still maintains the previous correlation.

Example # Correlate the interface Ethernet1/0 to the DHCP server group 1.

<Sysname> system-view

[Sysname] interface ethernet 1/0

[Sysname-Ethernet1/0] dhcp relay server-select 1
