Usage guidelines

When receiving a DHCP-DISCOVER message, the server compares the client against the user classes in the order that they are specified by this command. If a match is found, the server assigns the client the DHCP options in the option group. If multiple matches are found, the server selects option groups by using the following methods:

You can specify only one option group for a DHCP user class in a DHCP address pool. If you execute this command multiple times for a user class, the most recent configuration takes effect.

Examples

# Specify DHCP option group 1 for user class user in DHCP address pool 0.

<Sysname> system-view
[Sysname] dhcp server ip-pool 0
[Sysname-dhcp-pool-0] class user option-group 1
