Packets per second (PPS) Cisco SG500-52MP 52-port Gigabit Max PoE+

Hi,

This year we deployed over a hundred Chromebooks in one area of our school for the Gr 7's (1:1 ratio).  Yesterday I found that the Meraki MR32's in that area (I have 3 of them dedicated for that area of the school) were laggy in terms of authenticating students (radius auth).  I had roughly 40-50 kids per access point...so it was quite a good test/heavy load.  To be preventative and minimize any stress on the AP's in the future, I have increased the bit rate to eliminate A and B wireless protocol devices, in doing this the AP doesn't have to work hard on a low bit rate item and it kind of draws a line in the sand for the next AP to pick up the client.

Ok, now that I have done that, I was also curious about my switch, I did the command #show cpu input rate and found it was bouncing between 75 and 100, I attempted to find the specs on this switch that would show how many packets per second (pps) it can process, but could not find any info in the whitepapers I came across.

Is anyone able to shed some light on this, as I want to ensure the switch itself is up to the task of all those devices at once.

Thank you,

Don

Thank you,

Is there a quick calculator to change pps into mpps...Looked around on Google with no results for a conversion calculator or chart.

well Mpps stands for Millions of Packets Per Second. basically the same as PPS but 10^6. I hope this is what you are refering.
