IfIndex
The value of the instance of the ifIndex object,

defined in MIB-II, for the interface corresponding

to this port.
Circuit
For a port which (potentially) has the same value

of dot1dBasePortIfIndex as another port on the

same bridge, this object contains the name of an

object instance unique to this port.  For example,

in the case where multiple ports correspond 

one-to-one with multiple X.25 virtual circuits, this

value might identify an (e.g., the first) object

instance associated with the X.25 virtual circuit

corresponding to this port.

For a port which has a unique value of

dot1dBasePortIfIndex, this object can have the

value { 0 0 }.
DelayExceededDiscards
The number of frames discarded by this port due

to excessive transit delay through the bridge.  It

is incremented by both transparent and source

route bridges.
MtuExceededDiscards
The number of frames discarded by this port due

to an excessive size.  It is incremented by both

transparent and source route bridges.
