Remapping reference codes in pluggable modules to support different applications

A method of implemented in a pluggable module, the method comprising steps of:

• responsive to insertion of the pluggable module into a host device, advertising supported media interface modes by the pluggable module;
• receiving a code for one of the supported media interface modes;
• responsive to a remapping table stored in memory of the pluggable module, remapping the code to a different code for the pluggable module;
• and
• configuring a media interface based on the different code,
• wherein the remapping table is stored in a memory map of circuitry of the pluggable module that defines pairs of (i) a programmed media interface identifier received from the host device via an electrical interface and (ii) a target media interface identifier used internally by the pluggable module, and wherein the remapping comprises, responsive to receipt of the programmed media interface identifier from the host device, translating the programmed media interface identifier to the target media interface identifier and configuring the media interface based on the target media interface identifier.

A host device comprising:

• a slot including an electrical interface configured to communicate with a pluggable module;
• and
• circuitry configured to
• interface with the pluggable module,
• communicate modes for operation with the pluggable module, wherein the modes include a media interface mode defined by a code, and
• interface data with the pluggable module for operation thereof where the pluggable module operates in the media interface mode and the host device is configured with a different code remapped from the code,
• wherein the different code is a programmed media interface identifier recognized by the host device and communicated by the host device to the pluggable module via the electrical interface, wherein the pluggable module stores, in a memory map of circuitry of the pluggable module, a remapping table defining pairs of the programmed media interface identifier and a target media interface identifier used internally by the pluggable module, and wherein the host device remains configured with the programmed media interface identifier while the pluggable module operates using the target media interface identifier obtained by remapping the programmed media interface identifier.
