What is isisCircLevel?

Controls which level(s) of IS-IS PDUs (Level 1, Level 2, or both) this circuit sends and accepts, defaulting to level1L2 and further constrained by the router's overall isisSysType setting; like isisCircType, this can only be changed while the circuit is disabled. An admin restricts a circuit to 'level2' only on, for example, a backbone-only link where no Level 1 adjacency should ever form.
