How Do I Configure Multiple dhcp pools for Multiple VLANs on Switch?

If you only want to allocate different address pools to different VLANs, here is a sample configuration from S5700:

vlan batch 10 20
#
ip pool 10
gateway-list 192.168.1.1
network 192.168.1.0 mask 255.255.255.0
dns-list 10.0.0.1
#
ip pool 20
gateway-list 192.168.2.1
network 192.168.2.0 mask 255.255.255.0
#
interface Vlanif10
ip address 192.168.1.1 255.255.255.0
dhcp select global
#
interface Vlanif20
ip address 192.168.2.1 255.255.255.0
dhcp select global
#
interface GigabitEthernet0/0/1
port hybrid pvid vlan 10
port hybrid untagged vlan 10
#
interface GigabitEthernet0/0/2
port hybrid pvid vlan 20
port hybrid untagged vlan 20
# 

If you want to apply DHCP to a subnet-based VLAN, that’s a bit more complicated. You can check out the below link for configuration details: http://support.huawei.com/hedex/ ... E%2BConfiguration.
