Claim 13:
14. A method to upgrade a non-redundant stackable switch, the method comprising:
establishing, via a communication interface of a mobile computing device, a direct connection with the non-redundant stackable switch, wherein the non-redundant stackable switch comprises one or more host processors executing a control-plane that manage and maintain a plurality of data-plane-associated tables;
synchronizing control-plane states of the mobile computing device with control-plane states of the control-plane of the non-redundant stackable switch; and
receiving, over the direct connection, from the non-redundant stackable switch, a control-plane associated packet, or a message derived therefrom, the control-plane associated packet having been received at a port of the non-redundant stackable switch;
determining, via control-plane operations, updates to a portion of the plurality of data-plane-associated tables using the control-plane associated packet or the message derived therefrom; and
transporting, over the direct connection, to the non-redundant stackable switch, the determined updates to the portion of the plurality of data-plane-associated tables of a data-plane of the mobile computing device when the control plane of the non-redundant stackable switch is unavailable, wherein the non-redundant stackable switch is configured to receive the determined updates to the portion of the plurality of data-plane-associated tables and update the data-plane-associated tables of the dataplane of the non-redundant stackable switch.
