Looking for Definition of Cisco BUS or what Cisco BUS stands for?
Cisco BUS is an ATM that is part of an emulated LAN or LANE operation. By using data with multicast MAC addresses, then unicasting of the data into each LE client in the same emulated LAN, the BUS emulates the capacity of an 802.x LAN. Furthermore, if an LE client cannot, the BUS resolves the MAC addresses to ATM addresses. The server processes data sent to the MAC address, both multi-cast and original unicast frames that a LAN emulation consumer receives.
