SNMP—like any other high-level protocol that can be implemented using the DS33X162 family of products—requires software development by the customer. Maxim does not provide high-level protocol software at this time. The DS33X162 products provide the required hardware support needed to implement an SNMP agent for an RMON MIB in software. Specifically, the device allows trapping and insertion of unicast frames (i.e. Ethernet frame addresses assigned to the equipment). An “SNMP agent” is the software application that runs on the host microprocessor and processes the SNMP frames. To implement an SNMP agent, the user needs to develop (or purchase) software for a minimal TCP/IP stack to run on their microprocessor, including an ARP client. The DS33X162 also contains the hardware counters required for the RMON MIB. The SNMP agent needs to be able to handle the SNMP messages in software. The SNMP agent reads the hardware counters in order to respond to RMON messages. The customer could also dev
