Ethernet ports When a LEC receives an LE_ARP request it checks whether the MAC address is on its Switch It does this by checking the entries in the Switch database If the MAC address belongs to one of the devices connected to an Ethernet port the LEC sends an LE_ARP response to the LEC that sent the original LE_ARP request The LEC that sent the LE_ARP request adds this information to its ARP Table The LEC then sets up a direct connection through the ATM network to the appropriate LEC so that subsequent frames are forwarded more efficiently What Happens to Unicast Frames The path a unicast frame takes through the ATM network depends on whether the location of the destination address is known to the sending LEC e If the location of the destination address is known the LEC sets up a direct connection to the LEC serving the destination address e Ifthe location of the destination address is unknown a unicast frame is sent to the Broadcast and Unknown Server BUS where it is treated in the same way as a broadcast or multicast frame In addition the sending LEC attempts to locate the LEC serving the destination address It does this using the LE_ARP process described in LAN Emulation Address Resolution Protocol LE_ARP What Happens to Broadcast and Multicast Frames Each Emulated LAN ELAN acts as a broadcast domain When a broadcast or multicast frame is passed to the LEC for transmission the frame is sent to the Broad
