Systems and methods for verifying that an optical transceiver has access
privileges to received microcode. An example environment may include an
optical transceiver that is coupled to a host computing system. The
optical transceiver includes a memory that has thereon an optical
transceiver access identifier. The optical transceiver memory is also
configured to receive microcode that includes a microcode access
identifier. Whenever new microcode is received by the optical
transceiver, it is verified whether the optical transceiver should have
access privileges to the microcode. To verify that the optical
transceiver has access privileges, the optical transceiver access
identifier and the microcode access identifier are accessed. The accessed
identifiers are then compared with one another. Based on the comparison,
the received microcode is loaded into the memory if one or more portions
of the access identifiers match.
