        Number of active MCAST sessions:                 0
        Number of active predict sessions:               48
        Number of active SCTP sessions:                  0
        Number of active SCTP associations:              0
        Session table utilization:                       14%
        Number of sessions created since bootup:         1841876180
        Packet rate:                                      38578/s
        Throughput:                                      214833 kbps
        New connection establish rate:    366 cps

Thanks for your response.

I have already read this document but I'm still confused about which value I have to choose for DDos profile. If I made show session info which one to choose between :

Number of allocated sessions or packet rate or New connection establish rate.

Hi @Mamoudou ,

 

For classified DoS Protection profiles, measure the average and peak CPS of the individual devices you want to protect.

 

New connection establish rate: 366 cps

Hello,

 

Thank you for your response.

 

We want to use aggregate DoS Protection profiles what about this ?

If I get you I have to measure the average of "New connection establish rate" ?

 

Kind regards
