Hello, Thank you for your reply. In your link, I learned how to apply policies according to a schedule. And I still want to know whether it is possible to limit bandwidth after a certain download limit is reached by a user.

Hi all, First of all, I would like to thank u all in advanced. I have a couple of Meraki Wireless Access Points installed at my office. And I want to add some specific rules as below. First I want to know whether it is possible for me to add rules as I desire. And then I would like to know how to do so. I want to shape (reduce) the speed for Socal Media apps/sites (E.g. Facebook) whenever a user exceeds allocated maximum download limit (per month) on those applications, for only that particular user. E.g. If the user Bob has consumed 500mb on Facebook his bandwidth should be limited to 5mbps for the month of May. After the month of May, he should get a fresh unthrottled bandwidth to use Facebook up to the maximum data cap of 500mb. And other users who have not exceeded the data limit should not be affected. After 1800 hours (6.00pm) to 0830 hours (08.30 am) the data usage should not be counted and the bandwidth should not be throttled. E.g. Even Bob should be able to get the full bandwidth to browse Facebook from 1800 hours to 0830 hours. Thanks.

First understand what a Point-to-Point link is (just google and c images for a better understanding)
In a Single Point-to-Point link there’re 2 Points (as the name implies), one point each sides
And those Points can be considered as Hosts.
So in a Single Point-to-Point link there are 2 Hosts.
So for a single point-to-point link we must assign 2 valid IPs from a same subnet.
So to have 2 valid IPs the chosen subnet should have at least 4 IPs (2+2=4) (Remember we have to reserve 1 IP for the network ID and 1 IP for Broadcast ID)
I think up to this u have understood what I’m telling
So to have 1 Point-to-Point link we should have
1 Subnet and
So to have 113 Point-to-Point links we should have (at least)
1 x 113 = 113 Subnets
4 x 113 = 452 IPs (Hosts, u may call in subletting world)
So to have 452 IPs we should use a subnet of /27
Because /23 has 9 host bits so it can offer 512 (2^9) IPs and 510 (512-2) valid IPs we can have our required 452 IPs wasting a minimum of IPs
/24 subnet can only have 254 ((2^8)-2) valid IPs so not sufficient for our requirement of 452 IPs
and anything less than /23 like /22 /21 /20 /18 can be used for accommodate 452 IPs but we would have to waste more IPs
Another way to approach (not adviced to use)
And the networks with subnet mask /31 (borrowed 7 hosts bits from class c network) , /23 (borrowed 7 hosts bits from class b network) and /15 (borrowed 7 hosts bits from class a network) , we can have 113 subnetworks So by looking at the answers there's only one subnetwork that maches thoes cidr notation which is /23
