Bytes long
NOTE… Ethernet II/DIX frame preamble is 8 bytes long with no SD byte,
Ethernet II/DIX frame has TYPE field and no LENGTH or 802.2 fields.
Ethernet IEEE 802.3 frames have 7 byte preamble, 1 byte SD,
Ethernet IEEE 802.3 frames have LENGTH field and no TYPE field,
Ethernet IEEE 802.3 frames have 802.2 field for 2 byte DSAP, 2 byte SSAP, 2 control bytes and
5 byte SNAP (if used DSAP and SSAP = 0xAA).
Therefore the largest Ethernet frame size should be 1518 bytes and the minimum frame size should be 64 bytes
in order to stay within the Ethernet specification and be able to detect a collision. The frame size was extended
to 1522 bytes by a IEEE 802.3 committee workgroup (802.3ac) to support VLAN tagging using 802.1Q but
several manufactures equipment still will not support giant frames (larger than 1518). Frame sizes have been
pushed even further with the latest technologies. ISL (Inter Switch Link) VLAN tagging extends the frame
by an additional 30 Bytes, MPLS (Multi Protocol Label Switching) adds 4 Bytes for each label….. etc. etc. so
it is not unusual to see giant frames on today’s networks.
