Download mibs.zip - The Viper MIB is bundled with each unit's firmware. Click "Download mibs.zip" and a pop-up dialog box
will appear in your browser asking you to open or save the file to your PC. Save the zip file to a desired location. Unzip the
contents of mibs.zip file to a location where your SNMP manager can find it.
Caution: Certain MIB Browsers (standalone or integrated in SNMP Manager) may require you to modify the MIB files
extension (for example, from .MIB to .TXT).

MIB.
The manager and agent use a Management Information Base (MIB), a logical, hierarchically organized database of
network management information. MIB comprises a complete collection of objects used to manage entities in a
network. A long numeric tag or object identifier (OID) is used to distinguish each variable uniquely in the MIB and
SNMP messages.
Viper MIB Files
Each Viper firmware package is bundled with three MIB files (found inside mibs.zip file): (1) dataradio-regs.MIB contains a
top level set of managed object definitions aimed at managing Dataradio products, (2) 1213.MIB contains a set of managed
object definitions aimed at managing TCP/IP-based internets, and (3) VIPER.MIB contains a set of managed object
definitions aimed at managing Viper radio modems.
OID
In SNMP, each object has a unique OID consisting of numbers separated by decimal points. These object identifiers
naturally form a tree.
illustrates this tree-like structure for dataradio-regs.mib MIB, which comes bundled with
every Viper SC unit package. A path to any object can be easily traced starting from the root (top of the tree). For example,
object titled “dataradio” has a unique OID: 1.3.6.1.4.1.3732. The MIB associates each OID with a label (e.g. “dataradio”) and
various other parameters. When an SNMP manager wants to obtain information on an object, it will assemble a specific
message (e.g. GET packet) that includes the OID of the object of interest. If the OID is found, a response packet is assembled
and sent back. If the OID is not found, a special error response is sent that identifies the unmanaged object.
