The data provided by you is the hardware limit on the number of clients, which is a new and useful information for me. Thank you. But , My doubt is on the design of client vlan. If we have a large broadcast domain, whether we will face any issues. How many IP addresses per WLAN is an optimal design solution?
I never across this kind of question, not a easy question to answer.
Answer should be:
Yes or No.(You can have as many as you want but there are many limitation )
Two factor: Bandwidth & Resource
First, the bandwidth you are actually contending for isn't the back end ethernet link, but the wireless link speed. So on a 54 mbps router you would be contending for that 54 mbps. At 60 clients that would be about 900kbps each, not counting TCP overhead, counting TCP overhead you are already down to ~720kbps.
Secondly, you still have to deal with signal strength issues, which depending on your location could greatly effect throughput.
Rule of thumb was about 10-12 clients per AP for best performance, you can probably move that up to 20-25.
*** There is a client limit(Max IP address allocation ) on WLC for each wlan.
I am using /21 (2048 IP) per subnet in my network. For a given SSID I am using 3 of those subnets pool in together using interface group. I am using 5508 as WLC and keep those numbers as database size is 7000 for that platform.
We have similar number (16k) clients in our main campus, where load is shared onto 4x5508 WLC.
That's a tough question.....I have some clients use a /16 because they didn't want to break up their subnet's that they create long time ago... does it work, yes. Here is the thing though.... if you wanted to limit bonjour or multicast, how would you do that in a very large subnet. There are pro's and con's and you have to look at both. Many of my clients guest networks are /16 and works great, but my clients see that ask guest and use at your own risk. If your worried about large subnet's, look into interface groups in which you can bundle subnet's together.
