Abstract
A method may include storing updated firmware in storage of a target switch, transmitting instructions to the target switch to initiate a restart thereof, and transmitting a respective notification to (i) at least one switch in each of a core layer and aggregation layer of the computer system, and (ii) switches in an access layer if a switch of the aggregation layer is the selected target switch. The notification may be indicative of an impending shut down of the target switch and include instructions to each recipient switch to cease directing packets thereto. The method may also include processing any packets directed to the target switch prior to the receipt of the notification and compliance thereto by each recipient switch, confirming all packets directed to the target switch from each recipient switch have been received and processed, and restarting the target switch, thereby updating the firmware on the target switch.
