Ubiquiti AirOS by SNMP
Overview
This template is designed for the effortless deployment of Ubiquiti AirOS monitoring by Zabbix via SNMP and doesn't require any external scripts.

| Interface {#IFDESCR}: Operational status | MIB: IF-MIB The current operational state of the interface. - The testing(3) state indicates that no operational packet scan be passed - If ifAdminStatus is down(2) then ifOperStatus should be down(2) - If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic - It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection) - It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state - It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components. |
SNMP agent | net.if.status[ifOperStatus.{#SNMPINDEX}] |
| Interface {#IFDESCR}: Bits received | MIB: IF-MIB The total number of octets received on the interface,including framing characters.

| Interface {#IFDESCR}: Inbound packets with errors | MIB: IF-MIB For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. |

SNMP agent | net.if.out.errors[ifOutErrors.{#SNMPINDEX}] Preprocessing
|
| Interface {#IFDESCR}: Outbound packets discarded | MIB: IF-MIB The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. |

SNMP agent | net.if.type[ifType.{#SNMPINDEX}] Preprocessing
|
| Interface {#IFDESCR}: Speed | MIB: IF-MIB An estimate of the interface's current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth. If the bandwidth of the interface is greater than the maximum value reportable by this object then this object should report its maximum value (4,294,967,295) and ifHighSpeed must be used to report the interface's speed. For a sub-layer which has no concept of bandwidth, this object should be zero. |
