Aug 18, 2011 · Logical Link Control (LLC) is one of two Data Link Layer (DLL) network protocol sublayers within the Open System Interconnection (OSI) data communication model. LLC is located in the upper DLL area of OSI Layer 2 above the Physical Layer (PHY) of OSI Layer 1. LLC is standardized as IEEE 802.2 by the Institute of Electrical and Electronics

When IEEE took the DIX Ethernet and came up with its own 802.3 Ethernet, 802.2 LLC and 802 SNAP, another RFC - this time, RFC 1042 - came out that dealt with encapsulating IPv4 into these IEEE frame formats. This RFC is more complex to read but it basically stipulates that for 802.3 Ethernet networks, the 802 SNAP shall be used. Ethernet, LLC, your local Ethernet service solutions provider, offers business-class bandwidth and applications for your business and home. Ethernet Internet Access will support VoIP, a secure data VPN to the WAN at HQ, and a big Internet pipe – all at once - making a home office just another node on the network. GSM2224-POE.

802.3 (which uses 802.2 LLC format) has a Length field in the same place that Ethernet II has a Type field. IEEE 802.3 with 802.2 LLC (used by Spanning-Tree, ISIS) use the highlighted bytes for a Length field. 802.3 Upper-layer protocols are decoded via the 802.2 LLC Header / SNAP bytes.

Ethernet II frame, or Ethernet Version 2, or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol. Novell raw IEEE 802.3 non-standard variation frame; IEEE 802.2 Logical Link Control (LLC) frame; IEEE 802.2 Subnetwork Access Protocol (SNAP) frame 802.3 and 802.2 do not refer directly to physical architectures, but to the format of the layer 2 Ethernet frame. 802.2 is the default frame type for Netware 3.12 and 4.x, 802.3 is used for Netware 3.11 and earlier. 802.3 is a bit like Novell 802.3 raw + 802.2 LLC, created by IEEE for its own Ethernet specification. The Ethernet served as the basis for the IEEE 802.3 standard. SNAP. (RFC 1042, page 2) IP datagrams are sent on IEEE 802 networks encapsulated within the 802.2 LLC and SNAP data link layers, and the 802.3, 802.4, or 802.5 physical networks layers.

When transmitting data over Ethernet, the Ethernet frame is primarily responsible for the correct rulemaking and successful transmission of data packets. Essentially, data sent over Ethernet is carried by the frame. An Ethernet frame is between 64 bytes and 1,518 bytes big, depending on the size of the data to be transported.

Ethernet Extender is a concept and term that Enable-IT invented, branded and coined in the 90’s. Designed to transparently drive long distance Ethernet beyond the IEEE 802.3 specifications for today’s twisted pair wiring distance limitation of 328 feet or 100 meters, creating very cost-effective, bridged Ethernet connections. LLC: BACnet Ethernet uses LLC atop Ethernet as its transport protocol, and BACnet ARCNET uses LLC atop ARCNET as its transport protocol. For BACnet traffic, DSAP is 0x82, SSAP is 0x82. MSTP: BACnet MS/TP uses either MSTP natively, or from the Cimetrics U+4 converter, LLC SNAP as its transport protocol. Example traffic. Wireshark Ethernet Automation LLC is an Arizona Domestic L.L.C. filed on December 16, 2016. The company's filing status is listed as Good Standing and its File Number is L21452690 . The Registered Agent on file for this company is Legaling Corporated Services I and is located at 2 East Congress St Ste 900-126, Tucson, AZ 85701. Ethernet LLC--Logical Link Control The LLC sublayer takes the network protocol data, which is typically an IPv4 packet, and adds control info to help deliver the packet to the destination node. The LLC is used to communicate with the upper layers of the application and transition the packet to the lower layers for delivery. The two data link sublayers are as follows: Logical Link Control (LLC): Handles the communication between the upper layers and lower layers, typically hardware. MAC: The ethernet MAC sublayer has the following responsibilities: Data encapsulation, media access control, addressing.
