A method, device, and computer readable medium for managing overheat behavior in a network device. The method includes determining that a first temperature exceeds a threshold by at least one temperature sensor disposed in a network device. The method includes logging a temperature sensor name of the at least one temperature sensor, the first temperature, and actions taken prior to determining that the first temperature exceeds the threshold. The method further includes disabling network device capabilities and enabling a subset of network device capabilities after powering cycling the network device.

Overheat restart behavior in network devices

A method of operating a network device is provided. In response to an unplanned reboot, the network device can determine whether an unplanned reboot expedited recovery feature has been enabled on the network device. After determining that the unplanned reboot expedited recovery feature is enabled, the network device can identify a cause of the unplanned reboot. If the cause of the unplanned reboot is from a first set of events, a first bootup sequence can be performed. If the cause of the unplanned reboot is from a second set of events, a second bootup sequence that is expedited relative to the first bootup sequence can be performed.

Unplanned reboot expedited recovery for network devices

A method for managing a network device that includes a network operating system (NOS) and a third-party network operating system (3PNOS) includes detecting a 3PNOS state change in a 3PNOS database managed by the 3PNOS, translating the 3PNOS state change into a network device state change, storing the network device state change in a state database managed by the NOS, in response to the storing: detecting a change in the state database by a NOS agent executing in the NOS, initiating, in response to detecting the change in the state database, an update to hardware on the network device by the NOS, wherein the 3PNOS does not directly manage the hardware.

Network device supporting multiple operating systems to enable optimized use of network device hardware

Verifying a hardware license and controlling hardware features includes receiving a first part of a license payload and a license signature covering the license payload from a CPU, the license signature being generated using a private encryption key; receiving a second part of the license payload from a memory, the CPU being unable to modify the second part of the license payload; generating a hash using the first part and the second part of the license payload; and verifying the license signature using the hash and a public encryption key associated with the private encryption key. When the verifying is successful, communicating with circuitry to enable functionality of the circuitry specified in the license payload.

Hardware license verification

Embodiments described herein may relate to methods, systems, and/or instructions stored on non-transitory computer readable mediums for managing a boot personality of a network device. Managing a boot personality may include, while executing a first operating system on a network device in a first boot personality using a first processor, executing a command to modify a configuration of a hardware component of the network device to cause the network device to be configured in a second boot personality. The method may also include rebooting the network device; initializing, based on the configuration of the hardware component, a second processor before the first processor; and executing, after the initialization, a second operating system while the network device is in the second boot personality.
