- Has 30 byte encapsulation

Does 802.1p - which states the following:
Made up of 4 headers
- Ethertype: 0x8100
- 802.1P: 3 COS bits used for QOS Marking - is this referring to VOIP? & as ISL is more superior than 802.1q how come QOS Markings is NOT included in ISL?
- Token ring flag: 1 bit
- Vlan id: 12 bits (1-4094 range for vlans)
