NP7 HPE and high priority traffic

NP7 HPE and high priority traffic

The NP7 HPE high-priority option allows you to set a maximum overflow limit for high-priority traffic. The range is 1000 to 40000000 packets per second per host queue. The default high-priority setting is 40000.

By default, the high-priority overflow is applied to the following types of traffic that are treated as high-priority by the NP7 processor:

  • HA heartbeat
  • LACP/802.3ad
  • OSPF
  • BGP
  • IKE
  • SLBC
  • BFD

The high-priority setting adds an overflow for high priority traffic, causing the HPE to allow more of these high priority packets.

The overflow is added to the maximum number of packets allowed by the HPE based on other HPE settings. For example, by default, the HPE limits IKE traffic to all-protocol + pri-type-max pps, which works out to 400000 + 40000 = 440,000 packets per second per host queue.

The protocols that are considered high-priority by the HPE are defined by the configuration of the following command:

config system npu

config np-queues

end

You can use this command to add or remove high-priority traffic types. For more information, see Configuring NP7 queue protocol prioritization.
