Switch, router and access point monitoring over SNMPv3

A small probe on your LAN polls switches, routers and gateways over SNMPv3, with a named user, authentication and optional encryption, or over v2c, and reads UniFi controllers for access points. Ports, traffic, errors, neighbours and MAC tables are collected on every poll, and a one-minute check reports an unplugged cable or a dead device within about two minutes. Network equipment is part of Company mode, the device-centric view of an organisation's own network.

What it does

From the switch port to the access point

Credentials stay encrypted, devices that cannot be reached say so, and every finding says why.

🔐

SNMPv3 by design

Switches and routers are polled with a named SNMPv3 user, authentication and optional encryption, instead of a clear-text community string. The device form shows the exact commands to paste on a Cisco switch, and a dry run proves a device before it is trusted.

🔌

Ports, traffic and errors

Port status, traffic, errors, uptime and LLDP neighbours for every switch and router, with the MAC address table read from every VLAN, including Cisco per-VLAN tables over SNMPv3.

🔁

Loop and uplink audit

The MAC tables feed an audit that looks for loops and checks uplinks, so a topology problem is a finding instead of a long afternoon.

🚨

Alerts within about two minutes

The probe checks every device once a minute, so an unplugged cable or a device that goes down is reported within about two minutes. Alerts also cover restarts, power supply, fan and temperature faults, climbing errors and PoE reaching 90%.

📡

UniFi access points

Connect a UniFi controller and every adopted access point arrives with its clients, experience score, radios, SSIDs, uplink and firmware status.

🧭

Honest about what it cannot reach

A device that does not answer is shown as Unreachable with the reason, such as a rejected authentication password, a wrong privacy protocol or no reply, and is given up on in seconds so one dead switch cannot make the others look offline.

How it collects

One probe on the LAN, one command per device

The probe runs on any Linux or Windows host that can reach the devices, installs with the one command shown on each device's page, and pushes readings outbound over HTTPS. Device passwords are stored encrypted, device keys travel in a request header rather than the address, and a dry run polls one device and prints what came back before anything is saved.

FAQ

Anything else? Ask on the demo.

Is network equipment monitoring available in MSP mode?
Network equipment, Network Discovery, workstations and smart devices are part of Company mode, the device-centric view of an organisation's own network.
Which SNMP versions are supported?
SNMP v2c and SNMPv3. With v3, a named user, authentication and optional encryption replace the clear-text community string, and a device set to v3 without a username is never polled over v2c by mistake.
Does it work with Cisco switches?
Yes. Cisco IOS switches and routers are polled over SNMPv3 or v2c, including per-VLAN MAC address tables, which under v3 are read through vlan- SNMP contexts. The device form shows the exact commands to paste on the switch.
How does the probe reach my switches?
A small probe runs on any Linux or Windows host that can reach them, polls each device and pushes the readings to your dashboard outbound over HTTPS, so nothing connects into your network from outside. Each device has its own one-command setup, and a device the probe cannot reach is reported as Unreachable with the reason.
How are UniFi access points monitored?
Connect a UniFi controller with a read-only local admin account and monytr.ai pulls in every adopted access point, switch and gateway, with clients, experience score, radios, SSIDs and firmware status. The probe can run on the controller machine itself.
