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.

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.
