An example network device includes one or more hardware resources; a physical interface for receiving a hardware component; a memory; and one or more processors implemented in circuitry and configured to: receive the hardware component that has been coupled to the physical interface of the network device; receive data for an application programming interface (API) for the hardware component; store the data for the API to the memory; and execute the data for the API to grant the hardware component secure access to the hardware resources of the network device via the API. The hardware component may be an optical network interface. The resources may be raw registers of the network device. The processors may further tune the hardware component according to configuration for the network device, such as power management configuration for the network device, or the network device itself.

Adding third party hardware to network devices

In some implementations, a network device may cause instantiation of a base container associated with a line card of the network device. The network device may cause, based on causing the instantiation of the base container, instantiation of a module container associated with a physical interface module of the line card of the network device. The network device may manage, using the base container, a forwarding table associated with the line card. The network device may manage, using the module container, one or more physical components of the physical interface module.

A network device may receive traffic to be processed by a routing component, and may determine temperatures of an ASIC and an HBM of the routing component at a first time. The network device may determine whether the temperature of the ASIC satisfies a first ASIC temperature threshold or a second ASIC temperature threshold, and may determine whether the temperature of the HBM satisfies a first HBM temperature threshold or a second HBM temperature threshold. The network device may selectively throttle processing of the traffic by a first quantity when the temperature of the ASIC satisfies the first ASIC temperature threshold or the temperature of the HBM satisfies the first HBM temperature threshold, or throttle the processing of the traffic by a second quantity when the temperature of the ASIC satisfies the second ASIC temperature threshold or the temperature of the HBM satisfies the second HBM temperature threshold.

A network device that includes a plurality of packet processing components may receive traffic associated with one or more services. The network device may store state information for each of the plurality of packet processing components, while the plurality of packet processing components are receiving the traffic. The state information may include state configuration information and/or internal storage information. The state information may be stored using a data structure that is internal to the network device and external to the packet processing component. The network device may detect an error that prevents the packet processing component from processing at least a portion of the traffic. The network device may execute, based on detecting the error that prevents the packet processing component from processing at least the portion of the traffic, a recovery procedure that uses the state information to reset the packet processing component to an operational state.

A network device may include a packet generator device implemented in hardware. The packet generator device may include a control component, a payload generation component, and an interface element to receive test packet generation information. The test packet generation information may include one or more control inputs, header data that is to be included in one or more test packets, and information regarding a data pattern that is to be included in payload data of the one or more test packets. The one or more control inputs, when provided to the control component, may cause the control component to control the payload generation component to generate the one or more test packets based on the header data and the information regarding the data pattern.

A network device may identify a configuration of resources that are to support attachable line cards. The configuration may include a power supply configuration that is used to provide power to packet processing components that are supported by the line cards, and a resource distribution configuration indicating whether resources in the line cards are shared between the packet processing components. The network device may determine whether to modify a power state of a packet processing component based on whether one or more power modification conditions are satisfied. The network device may modify the power state of the packet processing component based on determining that the power modification condition is satisfied. The power state of the packet processing component may be able to be modified to a particular power state based on the configuration of resources.

A device may include one or more processors. The device may receive an instruction identifying a set of objects to be generated by a kernel associated with the device. The kernel may generate the set of objects based on receiving information identifying a corresponding set of write operations. The device may provide a first message to cause the kernel to perform first operations corresponding to a first subset of objects of the set of objects. The device may receive one or more notifications indicating whether each operation, of the first operations, was successfully performed. The device may determine, based on whether each operation was successfully performed, a quantity of objects to include in a second subset of objects, of the set of objects.

The message can include an error notification within a first subset of PCS lanes from the set of PCS lanes and not within a second subset of PCS lanes from the set of PCS lanes. The error notification is associated with signal degradation of a link from the set of links, where the switch device can send a first signal in response to receiving the message at the first time. The switch device can also receive at a second time a message without the error notification, and the switch device can send a second signal in response to receiving the message at the second time.
