Interface {#IFNAME}({#IFALIAS}): Bits sent

MIB: IF-MIB

The total number of octets transmitted out of the interface, including framing characters. This object is a 64-bit version of ifOutOctets.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.

Interface {#IFNAME}({#IFALIAS}): 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.

Interface {#IFNAME}({#IFALIAS}): Outbound packets with errors

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.

Interface {#IFNAME}({#IFALIAS}): 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.

Interface {#IFNAME}({#IFALIAS}): Interface type

MIB: IF-MIB

The type of interface.

Additional values for ifType are assigned by the Internet Assigned Numbers Authority (IANA),

through updating the syntax of the IANAifType textual convention.

Interface {#IFNAME}({#IFALIAS}): Speed

MIB: IF-MIB

An estimate of the interface's current bandwidth in units of 1,000,000 bits per second. If this object reports a value of n, then the speed of the interface is somewhere in the range of n-500,000 to n+499,999.

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.

For a sub-layer which has no concept of bandwidth, this object should be zero.

Trigger prototypes for Network interfaces discovery

Name Description Expression Severity Dependencies and additional info
Interface {#IFNAME}({#IFALIAS}): 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 the context macro to "0", marking this interface as not important. No new trigger will be fired if this interface is down.
3. last(/TEMPLATE_NAME/METRIC,#1)<>last(/TEMPLATE_NAME/METRIC,#2) - the trigger fires only if the operational status was up to (1) sometime before (so, does not fire for "eternal off" interfaces.)

WARNING: if closed manually - it will not fire again on the next poll, because of .diff.

 {$IFCONTROL:"{#IFNAME}"}=1 and last(/Mikrotik by SNMP/net.if.status[ifOperStatus.{#SNMPINDEX}])=2 and (last(/Mikrotik by SNMP/net.if.status[ifOperStatus.{#SNMPINDEX}],#1)<>last(/Mikrotik by SNMP/net.if.status[ifOperStatus.{#SNMPINDEX}],#2)) Average Manual close: Yes

The utilization of the network interface is close to its estimated maximum bandwidth.

Interface {#IFNAME}({#IFALIAS}): Ethernet has changed to lower speed than it was before

This Ethernet connection has transitioned down from its known maximum speed. This might be a sign of autonegotiation issues. Acknowledge to close the problem manually.
