VLAN ID

Specifies the VLAN to which the Ethernet frame belongs. A 12-bit
field specifying the VLAN to which the Ethernet frame belongs. The
hexadecimal values of 0x000 and 0xFFF are reserved. All other
values may be used as VLAN identifiers, allowing up to 4094 VLANs.
The reserved value 0x000 indicates that the frame does not belong to
any VLAN; in this case, the 802.1Q tag specifies only a priority and is
referred to as a priority tag. On bridges, VLAN 1 (the default VLAN
ID) is often reserved for a management VLAN; this is vendor specific.

VLAN Priority

Sets the frame priority level. Otherwise known as Priority Code Point
(PCP), VLAN Priority is a 3-bit field which refers to the IEEE 802.1p
priority. It indicates the frame priority level. Values are from 0
(lowest) to 7 (highest).

Differentiated Services (6-bit DSCP value)

Provides quality of service if the DSCP protocol is supported on your
network. Can be specified independently for SIP control packets
versus RTP audio packets.
