there are logs on my switch shows that a lot of CPCAR discarded packets, I thought to set the threshold to a higher value, but I did not find the correct command.

what's more, why the command display cpu-defend statistics packet-type arp-request all not work on my switch? this is the command which I found in the documentation.

my switch is s5720-pwr-li v200r011c10spc600

Hello!

These would be the default values for the threshold of the different packets: http://support.huawei.com/hedex/ ... Defense&lang=en.

You can modify the portattack defense function to ensure that valid protocol packets can be sent to the CPU.

You can check this command to adjust the its threshold: http://support.huawei.com/hedex/ ... reshold&lang=en.

In addition, that command is not available for all S switches.
