Abstract:
1. In an environment that includes an optical transceiver host computing system communicatively coupled using a protocol to each of a plurality of optical transceivers including at least a first optical transceiver and a second optical transceiver, wherein the protocol uses an addressing mechanism and in which the first and second optical transceiver each have the same host interface address under the addressing mechanism, a method for the optical transceiver host computing system to change a host interface address of the first optical transceiver without changing a host interface address of the second optical transceiver, the method comprising: an act of the optical transceiver host computing system indicating to the first optical transceiver and the second optical transceiver that an address change is pending in an address change request, wherein the address change request includes a new host interface address for the first optical transceiver; and an act of the optical transceiver host computing system using a mechanism other than the addressing mechanism of the protocol to inform the first optical transceiver to change its host interface address, wherein the first optical transceiver changes its host interface address while the second optical transceiver does not change its host interface address in response to the address change request.
