MSR2600同一局域网下通过dhcp class为不同用户组分配不同dns设置不成功

通过地址池中配置dhcp class来实现同一局域网中不通终端使用不同dns和网关等参数，实际未达到预期：

配置如下：

#

dhcp class abc

 if-match rule 5 hardware-address 50eb-7122-0000 mask ffff-ffff-0000

 if-match rule 6 option 12 ascii LIN-WORK

#

#

dhcp option-group 12

 option 3 ip-address 192.168.19.253

 option 6 ip-address 192.168.9.253

#     

dhcp server ip-pool vlan-interface2

 gateway-list 192.168.19.254

 network 192.168.19.0 mask 255.255.255.0

 address range 192.168.19.100 192.168.19.230

 class abc option-group 12

 dns-list 192.168.19.254

#

interface Vlan-interface2

ip address 192.168.19.254 255.255.255.0

 dhcp server apply ip-pool vlan-interface2

#

interface GigabitEthernet0/8

 port link-mode bridge

 port link-type trunk

 undo port trunk permit vlan 1

 port trunk permit vlan 2

 port trunk pvid vlan 2

实际在interface GigabitEthernet0/8下的windows终端获取到的dns和网关始终是192.168.19.254
