Note: VLAN settings are enabled. The device forwards packets based on the combination of the destination MAC address and VLAN ID.
The access port is used to connect to the endpoint. An access port forwards packets to only member ports of the native VLAN. The packets received or transmitted on this port are untagged.
The trunk port is used to connect to the switch. A trunk port may belong to multiple permit VLANs, but only packets of the native VLAN are untagged.
After VLAN settings are disabled, all VLAN setting swill be cleared and the device will forward packets according to the destination MAC address.
