Ethernet IEEE frames have 7 byte preamble, 1 byte SD, Ethernet IEEE frames have LENGTH field and no TYPE field, Ethernet IEEE frames have 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 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.

Newer equipment has auto-polarity MDI/X and some supply switchable MDI/MDI-X ports to enable connection of to devices without the use of a crossover cable. Some equipment uses the 15 pin D AUI connection ; pin # function 1 ground 2 CI-A 3 DO-A 4 ground 5 DI-A 6 VDC ground 9 CI-B 10 DO-B 11 ground 12 DI-B 13 VDC ground 15 ground KCC Feb 1998 NOTES; NOTE: Chiron makes use of RJ-11 connectors for the Cat-3 cabling for example an RJ-11 to RJ-45 cable ; RJ-11 pin # RJ-45 pin # LAYER 1 CCNA FastTrack CCNA FastTrack
