|SNMP agent|net.if.discovery| ### Item prototypes for Network interfaces discovery |Name|Description|Type|Key and additional info| |----|-----------|----|-----------------------| |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. Discontinuities in the value of this counter can occur at re-initialization of the management system, and another times as indicated by the value of ifCounterDiscontinuityTime.

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.in.errors[ifInErrors.{#SNMPINDEX}]**Preprocessing**
MIB: IF-MIB
For packet-oriented interfaces, the number of outbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of outbound 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**
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**

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.
|SNMP agent|net.if.speed[ifSpeed.{#SNMPINDEX}]| ### Trigger prototypes for Network interfaces discovery |Name|Description|Expression|Severity|Dependencies and additional info| |----|-----------|----------|--------|--------------------------------| |Interface {#IFDESCR}: Link down|This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. `{$IFCONTROL:"{#IFNAME}"}=1` - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. `{TEMPLATE_NAME:METRIC.diff()}=1` - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'eternal off' interfaces.)
WARNING: if closed manually - it will not fire again on the next poll, because of .diff.
The utilization of the network interface is close to its estimated maximum bandwidth.
