Parameters

class-name: Specifies the name of a DHCP user class, a case-insensitive string of 1 to 63 characters. If the specified user class does not exist, the DHCP server will not assign the addresses in the address range specified for the user class to any client.

start-ip-address: Specifies the start IP address.

end-ip-address: Specifies the end IP address.

Usage guidelines

The class command enables you to divide an address range into multiple address ranges for different DHCP user classes. The address range for a user class must be within the primary subnet specified by the network command. If the DHCP client does not match any DHCP user class, the DHCP server selects an address in the IP address range specified by the address range command. If the address range has no assignable IP addresses or no address range is configured, the address allocation fails.

You can specify only one address range for a DHCP user class in an address pool. If you use the class command multiple times for a DHCP user class, the most recent configuration takes effect.

After you specify an address range for a user class, you cannot use the network secondary command to specify a secondary subnet in the address pool.

Examples

# Specify an IP address range of 192.168.8.1 through 192.168.8.150 for the DHCP user class user in DHCP address pool 1.

<Sysname> system-view
[Sysname] dhcp server ip-pool 1
[Sysname-dhcp-pool-1] class user range 192.168.8.1 192.168.8.150
