ABSTRACT:
Packet switch operating methods and packet switches, using first processing circuitry of the packet switch, configure different second processing circuitry of the packet switch to periodically transmit control packets to a destination device via a port of the packet switch and, subsequent to the configuring and using the second processing circuitry, transmit the control packets to the destination device via the port during moments in time when the first processing circuitry is non-operational. Other packet switch operating methods and packet switches, using first processing circuitry of the packet switch, specify a configuration for a control packet processing procedure implemented by different second processing circuitry of the packet switch, communicate the configuration to the second processing circuitry, and using the second processing circuitry, transmit control packets according to the control packet processing procedure, the control packet processing procedure being configured according to the configuration.
