This value is the numeric Radio Link ID, from 1 to 99999, that both terminal ends of a microwave radio link must share in order to communicate. It functions like a pairing code rather than a network address, and the MIB notes it should be encrypted when carried across the network. For example, an installer sets wvLinkId to the same value, such as 4521, on both the near-end and far-end radios when commissioning a new point-to-point link.
