Abstract
A method of managing layer 2 devices uses SNMP protocol with an Ethernet connection without an USB or RS-232 port. When a gateway is setup to communicate with a client PC, an Ethernet packet with a pre-configured static IP address is sent out for the layer 2 device to read, intercept and process the payload in the IP packet of the Ethernet packet. If the gateway does not exist or is not set up properly for communication, a multicast frame to the address of 224.0.23.1 is sent out. The layer 2device recognizes the multicast address and process the protocol.
