 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 
interface GigabitEthernet0/0/5  ##接光猫1
 description to Modem1
 port link-type access
 igmp-snooping enable
 port default vlan 100

interface GigabitEthernet0/0/6  ##接光猫2
 description to Modem2
 port link-type access
 igmp-snooping enable
 port default vlan 200
 
interface GigabitEthernet0/0/7  ##接光猫3
 description to Modem3
 port link-type access
 igmp-snooping enable
