snmpv3-utils 0.4.1

SNMPv3 CLI testing utility — GET, WALK, SET, traps, credential testing

snmpv3-utils

A Python CLI for SNMPv3 testing. Most existing tools only support v1/v2 — this one does v3 properly.

Install

pipx install snmpv3-utils

Quick Start

# GET a single OID
snmpv3 query get 192.168.1.1 1.3.6.1.2.1.1.1.0 \
  --username admin \
  --auth-protocol SHA256 --auth-key myauthpass \
  --priv-protocol AES128 --priv-key myprivpass \
  --security-level authPriv

# WALK the system MIB
snmpv3 query walk 192.168.1.1 1.3.6.1.2.1.1 --profile myrouter

# Send a trap
snmpv3 trap send 192.168.1.1 --profile myrouter

# Test credentials
snmpv3 auth check 192.168.1.1 --profile myrouter

# Bulk test from a CSV
snmpv3 auth bulk 192.168.1.1 --file creds.csv

# JSON output (for piping into jq)
snmpv3 query walk 192.168.1.1 1.3.6.1.2.1.1 --format json | jq '.[] | .value'

Configuration

Copy .env.example to .env and fill in your defaults:

cp .env.example .env

Or use named profiles:

snmpv3 profile add myrouter \
  --username admin \
  --auth-protocol SHA256 --auth-key myauthpass \
  --priv-protocol AES128 --priv-key myprivpass \
  --security-level authPriv
