The size of the storage represented by this entry, in

writable to allow remote configuration of the size of

the storage area in those cases where such an

operation makes sense and is possible on the

the amount of disk space allocated to virtual memory

might be modified.

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

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.

|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,

|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.

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.
