PIR/max-burst ignored message

  • 772

After I typed the following police command for a type qos class on a Cisco Nexus 7000 switch:

police cir 8 kbps pir 8 kbps

I get the following message:

Note: pir/max-burst ignored

Can someone explain why PIR is ignored?

  1. Because the 7K has a hard policer. There is no notion of peak vs committed rates. Once you pass the CIR it will start dropping packets.
