SNMP Management: What AP parameters can I monitor over SNMP?

Products Enterprise Wi-Fi Networks
1

Starting from firmware release 2.0, the E series of access points support a Cambium MIB with various AP System and RF Parameters available for monitoring.

While the MIB file has all the details, a quick snapshot of the parameters now available for monitoring is:

AP System Information

part of  cambiumAccessPointEntry at (iso.3.6.1.4.1.17713.22.1.1.1)

  • AP MAC address
  • AP Hostname
  • AP IP Address (primary/mangement IP)
  • AP Serial Number
  • AP Firmware Version
  • Status of Connection to cnMaestro
  • Number of associated clients

Radio Information

Part of the cambiumRadioTable ((iso.3.6.1.4.1.17713.22.1.2.1). One row per radio.

  • Radio MAC address
  • Number of clients
  • Operating Channel
  • Current transmit power
  • TX and RX Packets
  • TX and RX Bytes

Wireless Client Information

Part of the cambiumClientTable ((iso.3.6.1.4.1.17713.22.1.3.1). One row per associated client.

  • Client MAC address
  • Client IP address
  • Client hostname (if learnt from DHCP)
  • SSID/WLAN client is associated with
  • HW vendor (based on MAC address)
  • VLAN
  • SNR
  • Data Rate (if known)
  • TX and RX packets
  • TX and RX bytes

WLAN Information

Part of the cambiumWlanTable ((iso.3.6.1.4.1.17713.22.1.4.1). One row per wlan.

  • SSID configured on Wlan
  • Radio band
  • VLAN
  • Security
  • Number of clients connected to the wlan
  • TX and RX packets
  • TX and RX bytes

Mesh Client Information

Part of the cambiumMeshClientTable ((iso.3.6.1.4.1.17713.22.1.5.1). One row per associated mesh client.

  • Mesh Client MAC address
  • Mesh Client IP address
  • Base AP MAC address
  • Client hostname
  • SSID/WLAN client is associated with
  • SNR
  • RSSI
  • Data Rate (if known)
  • TX and RX packets
  • TX and RX bytes

SNMP monitoring can be done even if the access point is being managed through cnMaestro: both the interfaces operate independent of each other.
