SNMP Agent with MIB II & RS-232 

Like Group 

NE-4100 Series modules have built-in SNMP (Simple Network Management Protocol) agent 
software. It supports SNMP Trap, RFC1317 RS-232 like group and RFC 1213 MIB-II. The 
following table lists the standard MIB-II groups, as well as the variable implementations for
