1. A method, comprising:
obtaining, by a first entity that communicates over a network with at least one second entity via a plurality of paths, an indication of one or more of a transmit power level and a receive power level of at least one target port associated with the second entity;
evaluating the one or more of the transmit power level and the receive power level of the at least one target port relative to at least one corresponding threshold; and
setting, by the first entity, a path state of one or more paths between the first entity and the at least one target port to a standby state based at least in part on the evaluating, wherein the first entity establishes paths between the first entity and one or more other target ports of the second entity in an active state;
wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
