8 Best Free MIB Browser Software For Windows

Here is a list of Best Free MIB Browser Software For Windows. MIB stands for Management Information Base which is a database used to manage different entities in a computer network using object identifiers (OIDs). It is mainly associated with Simple Network Management Protocol (SNMP). So, to view and explore MIB files, you need to use these MIB browser software. Most of these MIB Browsers provide the standard MIB files defined in Request For Comments (RFC). Using these, you get information about an object in the MIB tree including OID, MIB, Syntax, Access, Description, Type, etc.

While in some of these you can only view MIB files, few of these let you edit them as well. Apart from available MIB files, you can load new MIB files to have extended information on added SNMP agents. Most of these also let you query an SNMP agent using SNMP commands including Get, Get Next, Set, etc. A few of these also provide dedicated SNMP Walker tool which explores OID branches in a MIB tree. You also get MIB compiler tool in some of these to compile standard or vendor-specific MIB files. Most of them support all three versions of SNMP.

Though most of these are dedicated MIB explorer software, their respective brands provide separate SNMP monitoring software as well. So, you can download a suitable SNMP manager to easily monitor the performance of connected network devices within an enterprise.
