MIB Browser allows you to view the hierarchy of SNMP MIB variables in the form of a tree and provides you with additional information about each node. With MIB Browser you can easily load (compile) standard and proprietary MIB files, view and manipulate data that is available in an SNMP agent. MIB Browser may perform SNMP Get and Get_Next requests allowing you to check the propriety and current value of the counter on specific SNMP agent. By the way: you may find IP-Tools' SNMP Scanner utility useful for your needs. SNMP Scanner allows you to scan a range or list of hosts performing Ping, DNS and SNMP queries. For each SNMP responding device the scanner displays additional information.
