MIB Viewer

Generating SNMP Commands

Last updated September 10, 2026

MIB Viewer can generate a ready-to-run snmpget or snmpwalk command directly from an object you're looking at. This is available in two places - an OID page, and a MIB's object table - and works slightly differently in each. This guide covers both, plus how settings carry over between them, what SNMPv3 needs, and the CMD button shortcut in a MIB's object table.

On an OID page

Every OID page has a "Generate SNMP Command" button below the OID.

An OID page for clogNotificationsSent, showing the OID, a Generate SNMP Command button, and detail fields below it
The button sits below the OID on every object's page.

Clicking it opens a panel with connection fields and two commands: one to GET the object, one to WALK the subtree from it.

The command panel open, showing Host/Version/Community fields filled with 192.168.1.1 and public, and generated snmpget/snmpwalk commands using that host and OID
Filling in a host and community string updates both commands immediately.

Commands update live as you type. Host defaults to a <host> placeholder until you enter one.

Switching to SNMPv3

Selecting v3 replaces the Community field with Username, and adds a note about credentials the commands can't fill in for you.

The same panel with Version switched to v3, showing a Username field instead of Community, a note about auth/priv credentials, and generated commands using placeholders like <authpassword> for those credentials
v3 needs an authentication password, and a privacy password for authPriv - left as placeholders rather than stored in your browser.

An auth/priv password is a real secret, so it isn't requested or stored. The commands use -a SHA -x AES by default (see the SNMP Fundamentals guide for why), with <authpassword> and <privpassword> left for you to fill in.

On a MIB's object table

The same feature is available at the MIB level, next to Download, for any object in that MIB.

A MIB view for CISCO-SYSLOG-MIB showing both a Generate SNMP Command button and a Download button in the header, and a CMD button next to Copy in every row of the object table
Generate SNMP Command sits next to Download. Each row also has a CMD button next to Copy, covered below.

Opening it shows a mode toggle: Specific OID for one object, or Whole MIB to walk the module. Specific OID mode adds an object picker above the same fields as the OID page:

The MIB-level panel in Specific OID mode, with an Object dropdown set to clogNotificationsEnabled, and the same GET/WALK commands as the OID page would show for that object
Picking an object from the dropdown updates the commands the same way navigating to that object's own page would.

Whole MIB mode replaces the picker with a MIB directory field and generates one command that walks the module's entire namespace:

The MIB-level panel in Whole MIB mode, showing a note about walking from the module's common root OID, a MIB Directory field, and a single generated snmpwalk command using -M and -m flags
Whole MIB mode walks from the module's root OID, using -M to point at the MIB file's location and -m to load it.

Without -M/-m pointing at a real copy of the MIB, the walk still works, but output prints as numeric OIDs instead of names. Whole MIB mode only generates a WALK - a single GET for an entire module isn't a coherent request the way GET-one-object is.

The CMD button: jumping straight to one object

The CMD button next to Copy in every row skips the object picker and lands directly on that row:

After clicking the CMD button on the clogMessageGenerated row, the panel has scrolled into view, opened directly in Specific OID mode, and the object picker is already set to clogMessageGenerated
Clicking CMD scrolls to the panel, opens it if closed, switches to Specific OID mode if Whole MIB was active, and selects that row's object.

Settings carry over between both locations

Host, version, community/username, and the MIB directory field are stored in your browser and shared across every instance of this feature.

The MIB-level panel showing Host as 10.20.30.40 and Community as monitoring-ro, matching values that were typed earlier on a completely different object's OID page
These values were typed once on a different object's OID page. Opening the panel here already shows the same host and community.

This is stored locally in your browser, not sent anywhere - it saves retyping the same host and credentials for each object.
