With MIB Browser you can easily load (compile) standard and proprietary MIB files, view and manipulate data that is available in an SNMP agent.
When you are configuring SNMP Get or SNMP Trap test methods with MIB Browser installed HostMonitor allows you to specify SNMP variables by a name (e.g. iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0) as well as by an OID in numeric format (e.g. 18.104.22.168.22.214.171.124.0). If you click on "Browse MIBs" button next to "OID" field, HostMonitor will launch MIB Browser displaying the hierarchy tree of SNMP variables. The specified variable (if any) is highlighted and additional information is displayed for it (such as status, access mode, description). Now you may browse variables, choose another variable if needed and click [Ok] button to use the selected variable by HostMonitor.
Also, by using a database of compiled MIB files HostMonitor may translate OID from its numeric form to the MIB name for received SNMP Trap messages. In such case MIB Browser is needed when you want to extend a database to include information about MIBs supported by some specific SNMP enabled device (e.g. your CISCO 1603 router).
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. More information about SNMP Scanner is available at http://www.ks-soft.net/ip-tools.eng/mframe.htm#info.htm#snmpscan
Interface of the browser is simple and straightforward so we note just few key points:
Main screen displays the hierarchy of SNMP MIB variables in the form of a tree and provides you with the following additional information about each node of the tree:
- • Name
- • OID
- • SYNTAX
- • Access
- • Status
- • Description
- • Press "+" or "*" to expand a tree node. If you press "+", immediate sub-nodes of the selected node will be displayed. If you press "*", all descendants of the immediate sub-nodes will be expanded as well. When the node is expanded the [-] button appears next to the node name.
- • To collapse a tree node press "-". When a node is collapsed, all of its sub-nodes are hidden and the [+] button will be displayed near the node name.
