Priority is a 3-bit field, referring to 802.1p priority. Refer to section "QoS & QoS
profile" for details.
CFI is a 1-bit field, indicating whether the MAC address is encapsulated in the
standard format in different transmission media. This field is not described in detail
in this chapter.
VLAN ID is a 12-bit field, indicating the ID of the VLAN to which this packet
belongs. It is in the range of 0 to 4,095. Generally, 0 and 4,095 is not used, so the
field is in the range of 1 to 4,094.
VLAN ID identifies the VLAN to which a packet belongs. When the switch receives a
packet carrying no VLAN tag, it will encapsulate a VLAN tag with the default VLAN ID of
the inbound port for the packet, and the packet will be assigned to the default VLAN of
the inbound port for transmission. For the details about setting the default VLAN of a
port, refer to section "Port Basic Configuration" in H3C S3100-52P Ethernet Switch
Operation Manual.

1.2 Port-Based VLAN

Port-based VLAN technology introduces the simplest way to classify VLANs. You can
isolate the hosts and divide them into different virtual workgroups through assigning the
ports on the device connecting to hosts to different VLANs.
This way is easy to implement and manage and it is applicable to hosts with relatively
fixed positions.
