The SNAP header is used when the LLC protocol carries IP packets and contains the information which would otherwise have been carried in the 2-byte MAC frame type field.Click to see full answer. Similarly, it is asked, what is the purpose of the snap protocol?SubNetwork Access Protocol (SNAP) refers to a standard used for transmitting IP datagrams across IEEE 802 networks. This means that the IP datagrams can be routed on IEEE 802 networks encapsulated inside the SNAP data link layers 802.3, 802.4 or 802.5, physical network layers, and the 802.2 LLC.Beside above, what is LLC Logical Link Control and why do we need it? The function of the Logical Link Control (LLC) is to manage and ensure the integrity of data transmissions. The LLC provides Data Link Layer links to services for the Network Layer protocols. This is accomplished by the LLC Service Access Points (SAPs) for the services residing on network computers. Simply so, what is a snap header? Definition of snap header. 1 : a half brick appearing like a header in a masonry face but not extending in beyond the facework.Why is 802.2 necessary?802.2 is concerned with managing traffic over the physical network. It is responsible for flow and error control. The Data Link Layer wants to send some data over the network, 802.2 Logical Link Control helps make this possible. It also helps by identifying the line protocol, like NetBIOS, or Netware.
