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.

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.

MIB: IF-MIB

The number of inbound 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.

Preprocessing:

- CHANGE_PER_SECOND

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.

Preprocessing:

- CHANGE_PER_SECOND

MIB: IF-MIB

The total number of octets received on the interface, including framing characters. This object is a 64-bit version of ifInOctets. 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.

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,

Preprocessing:

- CHANGE_PER_SECOND

- MULTIPLIER: 8

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.

Preprocessing:

- MULTIPLIER: 1000000

- DISCARD_UNCHANGED_HEARTBEAT: 1h

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.

Preprocessing:

- DISCARD_UNCHANGED_HEARTBEAT: 6h

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.

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

Recovery expression:

- PFSense: Interface [{#IFNAME}({#IFALIAS})]: Link down

This trigger expression works as follows:

1. Can be triggered if operations status is down.

2. {$IFCONTROL:"{#IFNAME}"}=1 - 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.
