Which ports are supported by S9300 switch current L2VPN configuration?
Current L2VPN supporting ports mode：
1、vlanif interface configuration
Interface configuration limit：the packet accessed in interface must take vlan，interface add vlan by trunk way or hybird way. If it add to interface by default mode，unknow unicast and broadcast packet will be discarded. the reason is because S9300 using Broadcom chip.
2、sub interface configuration
interface configuration limit：nothing, sub interface must configure vlan that it can be used, so the inbound interface packet must take vlan, nor they will be discarded.
3、main interface configuration
S9300 default physical interface mode is switch mode，after S9300V1R2 version，use undo switchport command，change switch port to route port，that is layer 3 interface，but the layer 3 interface cannot configure ip address，it does not need to configure vlan，it can bind L2VPN（VLL，VPLS），inbound packet does not limit for vlan，it can take any vlan or not.
