SNMP polling collects interface counters, device health, and environmental data from network gear. Polling runs from gateways so credentials and traffic stay on-site.
Credentials and interval
On the gateway's Configuration tab (or globally — the Global → Cluster → Gateway hierarchy applies), configure the SNMP section:
- Version —
v2corv3 (authPriv). Prefer v3 wherever devices support it. - For v2c: the Community string (default
public— change it). - For v3: Username, Auth Type SHA + auth password, Privacy Type AES + privacy password.
- Poll Interval — default 60s, appropriate for interface counters.
Targets are managed per device, and each device row can carry its own credential set — useful mid-migration when half the estate is still on v2c.
Assigning what gets polled: OID profiles
Beyond standard interface and host OIDs, devices can be assigned an OID profile — a named set of OIDs with its own poll interval. Manage profiles under Settings → Vendor Integrations (MIB Library) → OID Profiles, then assign them from the device's page in Network → SNMP Devices.
Vendor MIBs
The platform seeds standard MIBs (IF-MIB, SNMPv2, HOST-RESOURCES, ENTITY) plus Cisco, Ubiquiti, Fortinet, and Extreme EXOS/VOSS out of the box. Upload additional vendor MIBs (.mib, .my, .txt) under MIB Library → Vendor MIBs; vendor is auto-detected and you tag the device type (switch, router, firewall, access point, …).
Exploring a device: SNMP Walk
When you're not sure what a device exposes, use MIB Library → SNMP Walk: enter the target IP, version and credentials, and a Root OID, and walk the tree live. Results are categorized, and you can Save as Device MIB to turn a useful walk directly into a pollable definition.
Verify
Network → SNMP Devices shows each device's interface table with traffic bars and time-series once polling succeeds. No data usually means a credential mismatch or UDP 161 blocked between gateway and device.
