SNMP MIB Browser & OID Walkthrough: Find and Monitor Any Device Metric

Q: ### How do I find OIDs for a device with no MIB file available?

Do a full `snmpwalk` starting from `.1.3.6.1` and save the output. Search through it for relevant values. You can also look up the enterprise number from `sysObjectID` on IANA's enterprise number registry to identify the vendor.

A practical guide to using MIB browsers, walking OID trees, and finding the right OIDs to monitor any SNMP-enabled device — routers, switches, UPS, printers, and custom hardware.

What Are MIBs and OIDs?

Every piece of information available via SNMP is identified by an Object Identifier (OID) — a unique numerical address in a hierarchical tree. A Management Information Base (MIB) is essentially a dictionary that translates these numeric OIDs into human-readable names.

The OID Tree Structure

iso(1)
 └── org(3)
      └── dod(6)
           └── internet(1)

                          └── APC(318)       → 1.3.6.1.4.1.318

Standard MIBs (under 1.3.6.1.2.1) work across all vendors — interface statistics, IP routing, system info. Enterprise MIBs (under 1.3.6.1.4.1) contain vendor-specific data like hardware sensors, proprietary features, and device-specific metrics.

Essential Standard OIDs Every Admin Should Know

These OIDs work on virtually any SNMP-enabled device:

System Information (1.3.6.1.2.1.1)

| OID | Name | Returns | |-----|------|---------| | .1.3.6.1.2.1.1.1.0 | sysDescr | Device description, firmware version | | .1.3.6.1.2.1.1.2.0 | sysObjectID | Vendor/model identifier | | .1.3.6.1.2.1.1.3.0 | sysUpTime | Time since last reboot (in timeticks) | | .1.3.6.1.2.1.1.4.0 | sysContact | Admin contact info | | .1.3.6.1.2.1.1.5.0 | sysName | Hostname | | .1.3.6.1.2.1.1.6.0 | sysLocation | Physical location string |

bash

# Quick device identification
snmpget -v2c -c public 192.168.1.1 sysDescr.0 sysName.0 sysUpTime.0

Interface Table (1.3.6.1.2.1.2.2.1)

| OID Suffix | Name | Returns | |------------|------|---------| | .1 | ifIndex | Interface number | | .2 | ifDescr | Interface name (e.g., GigabitEthernet0/1) | | .5 | ifSpeed | Interface speed in bits/sec | | .7 | ifAdminStatus | Admin state: 1=up, 2=down | | .8 | ifOperStatus | Operational state: 1=up, 2=down | | .10 | ifInOctets | Bytes received (32-bit counter) | | .14 | ifInErrors | Input errors | | .16 | ifOutOctets | Bytes transmitted (32-bit counter) | | .20 | ifOutErrors | Output errors |

bash

# List all interfaces and their status
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.2.1.2.2.1.2   # Names
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.2.1.2.2.1.8   # Oper status

# Get traffic counters for interface 1
snmpget -v2c -c public 192.168.1.1 ifInOctets.1 ifOutOctets.1

64-bit Counters (IF-MIB, 1.3.6.1.2.1.31.1.1.1)

For gigabit+ links, 32-bit counters wrap around too quickly. Use the 64-bit HC (High Capacity) counters:

| OID Suffix | Name | Purpose | |------------|------|---------| | .6 | ifHCInOctets | 64-bit input bytes | | .10 | ifHCOutOctets | 64-bit output bytes | | .15 | ifHighSpeed | Interface speed in Mbps |

bash

# 64-bit traffic counters for 10Gbps link
snmpget -v2c -c public 192.168.1.1 \
  1.3.6.1.2.1.31.1.1.1.6.1 \
  1.3.6.1.2.1.31.1.1.1.10.1

Finding the Right OIDs for Your Device

Step 1: Download the Vendor MIB

Every manufacturer provides MIB files for their devices. Where to find them:

| Vendor | MIB Location | |--------|-------------| | Cisco | Built into IOS, also on cisco.com SNMP Object Navigator | | Moxa | Product support page → Downloads → MIB files | | HP/Aruba | Support portal → MIB download | | APC/Schneider | APC download portal → Firmware/MIB | | Fortinet | Fortinet support → FortiMIB downloads | | Huawei | Enterprise support → MIB files |

Step 2: Load and Browse the MIB

bash

# Copy MIB files to Net-SNMP MIB directory
# Linux:
cp MOXA-SWITCHING-MIB.mib /usr/share/snmp/mibs/

# Then use the MIB name in commands:
snmpwalk -v3 -u myUser -l authPriv -a SHA -A "AuthPass" \
  -x AES -X "PrivPass" -m MOXA-SWITCHING-MIB 192.168.1.1 moxa

Step 3: Full Device OID Discovery Walk

When you don't know what OIDs a device supports, do a full walk:

bash

# Walk the entire device (can take minutes on complex devices)
snmpwalk -v3 -u myUser -l authPriv -a SHA -A "AuthPass" \
  -x AES -X "PrivPass" 192.168.1.1 . > full_walk.txt

# Search for specific keywords in the output
grep -i "temperature" full_walk.txt
grep -i "fan" full_walk.txt
grep -i "power" full_walk.txt
grep -i "cpu" full_walk.txt
grep -i "memory" full_walk.txt

# Walk only the enterprise subtree for vendor-specific OIDs
snmpwalk -v3 -u myUser -l authPriv -a SHA -A "AuthPass" \
  -x AES -X "PrivPass" 192.168.1.1 1.3.6.1.4.1 > enterprise_walk.txt

Step 4: Identify the Enterprise OID

bash

# Find the vendor's enterprise number
snmpget -v2c -c public 192.168.1.1 sysObjectID.0

# Example results:
# Cisco:  1.3.6.1.4.1.9.1.xxx
# Moxa:   1.3.6.1.4.1.8691.xxx
# APC:    1.3.6.1.4.1.318.xxx
# HP:     1.3.6.1.4.1.11.xxx

Practical Walkthrough: Finding CPU & Temperature OIDs

Example: Cisco Switch

bash

# CPU utilisation (last 5 seconds, 1 min, 5 min)
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.4.1.9.9.109.1.1.1.1

# CISCO-PROCESS-MIB OIDs:
# .3 = cpmCPUTotal5sec  (5-second average)
# .4 = cpmCPUTotal1min  (1-minute average)  ← most useful
# .5 = cpmCPUTotal5min  (5-minute average)

# Temperature sensors
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.4.1.9.9.13.1.3.1.3
# CISCO-ENVMON-MIB::ciscoEnvMonTemperatureStatusValue

Example: APC UPS

bash

# Battery capacity remaining (%)
snmpget -v2c -c public 192.168.1.50 1.3.6.1.4.1.318.1.1.1.2.2.1.0

# Battery temperature (°C)
snmpget -v2c -c public 192.168.1.50 1.3.6.1.4.1.318.1.1.1.2.2.2.0

# Battery runtime remaining (timeticks)
snmpget -v2c -c public 192.168.1.50 1.3.6.1.4.1.318.1.1.1.2.2.3.0

# UPS output load (%)
snmpget -v2c -c public 192.168.1.50 1.3.6.1.4.1.318.1.1.1.4.2.3.0

# Last transfer reason
snmpget -v2c -c public 192.168.1.50 1.3.6.1.4.1.318.1.1.1.3.2.5.0

Example: HP/Aruba Switch

bash

# CPU utilisation
snmpget -v2c -c public 192.168.1.1 1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0

# Temperature sensor
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4

# Fan status
snmpwalk -v2c -c public 192.168.1.1 1.3.6.1.4.1.11.2.14.11.1.2.6.1.4

# Memory utilisation
snmpget -v2c -c public 192.168.1.1 1.3.6.1.4.1.11.2.14.11.5.1.1.2.2.1.1.6.1

Creating Custom Monitoring with Discovered OIDs

Once you've found the right OIDs, integrate them into your NMS:

Zabbix Item Configuration

Type: SNMPv3 agent
SNMP OID: 1.3.6.1.4.1.318.1.1.1.2.2.1.0
Key: ups.battery.capacity
Type of information: Numeric (unsigned)
Units: %
Update interval: 60s

SNMPv3 security name: upsMonitor
SNMPv3 security level: authPriv
SNMPv3 auth protocol: SHA
SNMPv3 auth passphrase: {$SNMP_AUTH}
SNMPv3 priv protocol: AES
SNMPv3 priv passphrase: {$SNMP_PRIV}

Zabbix Trigger

Trigger: UPS Battery Low
Expression: last(/UPS Template/ups.battery.capacity) < 50
Severity: High

LibreNMS Custom OID Poller

In LibreNMS, add custom OIDs via the web UI:

Navigate to Device → Health → Custom OID
Add OID: 1.3.6.1.4.1.318.1.1.1.2.2.1.0
Set description, type (gauge), unit (%), divisor if needed
LibreNMS will graph it automatically

Tips for Efficient OID Discovery

Start with sysDescr — Know exactly what device and firmware you're dealing with
Check the vendor's documentation first — Most vendors publish OID reference guides
Use snmpbulkwalk instead of snmpwalk — 5-10x faster for large walks
Search enterprise OID databases online — Sites like oid-info.com catalog thousands of enterprise OIDs
Save full walks as reference — A complete OID dump serves as documentation for that device model
Compare walks across firmware versions — OIDs can change between firmware upgrades

Frequently Asked Questions

How do I find OIDs for a device with no MIB file available?

Do a full snmpwalk starting from .1.3.6.1 and save the output. Search through it for relevant values. You can also look up the enterprise number from sysObjectID on IANA's enterprise number registry to identify the vendor.

Can I create custom OIDs on a device?

Some devices support SNMP extend or pass-through mechanisms. On Linux servers, you can use extend in snmpd.conf to expose custom script output via SNMP. Network devices generally don't support custom OIDs.

Why does snmpwalk return "No more variables left in this MIB View"?

This usually means the SNMP user/community has restricted access. Check the SNMP view configuration on the device and ensure your user has access to the OID subtree you're trying to walk.

How often should I poll SNMP OIDs?

For counters (traffic, errors): 60-300 seconds. For status values (interface up/down): 30-60 seconds. For environmental (temperature): 120-300 seconds. Avoid polling faster than every 10 seconds unless absolutely necessary.

LibreNMS Custom OID Poller

In LibreNMS, add custom OIDs via the web UI:

Navigate to Device → Health → Custom OID
Add OID: 1.3.6.1.4.1.318.1.1.1.2.2.1.0
Set description, type (gauge), unit (%), divisor if needed
LibreNMS will graph it automatically

Tips for Efficient OID Discovery

Start with sysDescr — Know exactly what device and firmware you're dealing with
Check the vendor's documentation first — Most vendors publish OID reference guides
Use snmpbulkwalk instead of snmpwalk — 5-10x faster for large walks
Search enterprise OID databases online — Sites like oid-info.com catalog thousands of enterprise OIDs
Save full walks as reference — A complete OID dump serves as documentation for that device model
Compare walks across firmware versions — OIDs can change between firmware upgrades

Frequently Asked Questions

How do I find OIDs for a device with no MIB file available?

Can I create custom OIDs on a device?

Why does snmpwalk return "No more variables left in this MIB View"?

This usually means the SNMP user/community has restricted access. Check the SNMP view configuration on the device and ensure your user has access to the OID subtree you're trying to walk.
