What is isisCircIfSubIndex?

Identifies a sub-part of the interface (such as a Frame Relay DLCI or ATM VPI/VCI) that this circuit corresponds to; it cannot be changed after circuit creation. DC-ISIS ignores this field entirely, so an admin need not set it meaningfully on this implementation even though the object exists for MIB compatibility.
