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:
If the option groups have options in common, the server selects the option group specified for the first matching user class.
If the option groups have different options, the server selects all the matching option groups.
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
