[FWA515] - Feature request — SNMP monitoring support

Maverick87 · November 3

Dear Zyxel Product Management and Support Team,

I would like to request native SNMP monitoring support for the Zyxel FWA515.

Could you please confirm whether SNMP is already available in the current firmware? If not, please consider implementing it in a future firmware release.

SNMP support would allow the FWA515 to integrate with monitoring platforms such as Zabbix, PRTG and LibreNMS, enabling historical performance analysis, proactive alerts and faster troubleshooting alongside the existing management options.

The following information would be particularly valuable:

1. Cellular connectivity and radio quality

Network registration and data connection status, including the current access technology: LTE, 5G NSA or 5G SA.
Signal measurements: RSRP, RSRQ, SINR and RSSI, where available. In NSA mode, LTE and 5G NR measurements should be exposed separately.
Serving operator, MCC/MNC, roaming status and SIM readiness, including missing SIM or PIN-required states.
Serving cell identifiers, including Cell ID, PCI and TAC, with LTE and NR identifiers distinguished where applicable.
Active LTE/NR bands, EARFCN/NR-ARFCN, channel bandwidth and carrier aggregation details, including primary and secondary carriers where exposed by the modem.

2. WAN availability, traffic and failover

Cellular and Ethernet WAN operational status, the currently active WAN connection, and failover/failback events.
Cellular connection uptime, reconnection count, last disconnection reason and time of the last connection change.
Active APN and WAN IPv4/IPv6 addresses.
64-bit transmit and receive counters for each relevant interface, together with packet counters, errors and discards.
Results of existing WAN health checks, including reachability, latency and packet loss if these are already measured by the router. This would help distinguish a registered cellular connection from working Internet access.

3. Device health

Model, serial number, hardware revision, router firmware version and modem firmware version.
Device uptime, CPU utilisation and memory usage.
Temperature, power consumption and hardware alarms, where supported by the available sensors.

4. Ethernet and Wi-Fi status

Ethernet port link status, negotiated speed, duplex mode and traffic/error counters.
Wi-Fi radio and SSID operational status, channel, channel utilisation and associated client counts.
Wi-Fi traffic, retransmission and error counters, where available.

5. Event notifications

Please also consider SNMPv3 traps or informs for:

Device restart and interface link-up/link-down events.
Cellular registration or data connection loss and recovery.
WAN failover and failback.
Signal-quality threshold crossings and overheating, with configurable thresholds and hysteresis to avoid excessive notifications.

Security and implementation requirements

SNMPv3 with authentication and encryption (authPriv), using modern authentication and privacy algorithms.
Read-only monitoring by default, configurable access restrictions for authorised monitoring servers, and no exposure to the public WAN by default.
Standard MIBs such as SNMPv2-MIB, IF-MIB and IP-MIB, supplemented by a documented Zyxel enterprise MIB for cellular-specific information.
Downloadable MIB files and an OID reference documenting units, scaling, update intervals, counter resets and how unavailable measurements are represented.
Support for efficient polling through GET and GETBULK, without affecting routing performance.
Monitoring in both standalone and Nebula-managed operation, ideally without requiring cloud connectivity.
No exposure of SIM PIN/PUK values, passwords or other credentials.

For an initial implementation, the highest-priority features would be secure SNMPv3 access, cellular signal metrics, WAN status, 64-bit traffic counters and connection-loss/failover notifications.

Could you please advise whether this enhancement is feasible, whether it is already on the product roadmap, and which firmware release could introduce it? I would also be interested in participating in beta testing.

Best regards
