Abstract: In some implementations, a first packet forwarding device (PFD) may obtain a probe packet. The first PFD may replicate the probe packet forming multiple copies of the probe packet. The first PFD may transmit, to the first PFD and to multiple other PFDs, the multiple copies of the probe packet. The first PFD may receive a first copy of the probe packet and multiple response packets, with the first copy of the probe packet originating at the first PFD, and with each of the multiple response packets originating at a respective one of the multiple other PFDs based on the respective one of the multiple other PFDs receiving one of the multiple copies of the probe packet. The first PFD may determine, based on the first copy of the probe packet and the multiple response packets, a status of multiple links associated with the first PFD.

Abstract: A network device includes match filters to be applied to packets transiting two or more network interfaces. In one example, a network device includes a filtering unit configured to apply one or more filters to a first packet transiting a first network interface to determine a first rule the first packet matches, send the first packet and data representing the first network interface to a first accounting filter associated with the first rule, apply the filters to a second packet transiting a second network interface to determine a second rule that the second packet matches, the second packet being different than the first packet, and the second network interface being different than the first network interface, and send the second packet and second data representing the second network interface to a second accounting filter associated with the second rule.
