This value sets the polling interval used to periodically attempt resolving next-hops that are currently unresolved for equal-cost multipath routes, the counterpart to zyLoadSharingAgingTime's handling of already-resolved next-hops, per the source description. A network administrator tunes this to control how quickly a previously unreachable next-hop gets picked back up once it becomes available again. For example, lowering zyLoadSharingDiscoverTime would let the switch retry resolving a currently-unresolved load-sharing next-hop more frequently, bringing it back into rotation sooner once it recovers.
