Abstract:
An STP warm reboot system includes first switch device(s) including first switch ports, and a second switch device including second switch ports linked to respective first switch ports. During a warm reboot, the second switch device blocks designated-state second switch ports that are linked to first switch ports that have either an alternate role or a discarding state, redirects BPDUs identifying a designated peer port role and received on designated-state second switch ports from their respective linked first switch ports back to those first switch ports, and identifies topology change notification(s) received on the second switch ports. Subsequent to the warm reboot process, the second switch device reprograms the second switch ports that have experienced a state change during the warm reboot, and sends a topology change notification based on the identification of the topology state change notification received by the second switch ports during the warm reboot.

Claim (Index 14):
A method for providing spanning tree protocol warm reboots, comprising:\n blocking, by a first switch device during a warm reboot of the first switch device, first switch ports on the first switch device that have a designated state and that are linked to second switch ports on a second switch device that have either an alternate role or a discarding state; redirecting, during the warm reboot by the first switch device on first switch ports that have the designated state, first bridge protocol data units (BPDUs) that identify a designated peer port role and that are received from their respective linked second switch ports back to those second switch ports; and identifying, during the warm reboot by the first switch device on the first switch ports, at least one topology change notification received by those first switch ports; reprogramming, subsequent to the warm reboot by the first switch device, at least some of the first switch ports that have experienced a state change during the warm reboot; and sending, subsequent to the warm reboot by the first switch device and based on identifying the at least one topology change notification received by the first switch ports during the warm reboot, a topology change notification on a forwarding first switch port.
