Wired / Wireless

[vishal.rane]

Hello All

is the time arrived to replace all wired connection for users with wireless. 95% of the users are laptop users

Assuming:-

new campus with 1000 users with mix of apps users, email users, portal users.

should we still invest on wired for users ( keeping telephony not in the scope )

what is missing in wireless to completely overcome wired network for users

Experts please share your thoughts

thanks

PFA for IT best practices for WLAN deployment. Its a short doc , very informative though. Hope it helps

Here is my 2 cents....

Like Rasika mentioned, you now have to look at density no matter what. You either take the number of users and multiple by 2.5 or 3 to be safe and that is how you will determine how many APs you need. I would go with 20-30 max devices per AP also and any large conference rooms or training rooms would get two AP's.

Now you need to look at what you what to do for wireless. The 5760/3850 doesn't support FlexConnect because its a different technology. Since AP's terminate capwap directly at the 3850, FlexConnect isn't needed. The design for converged access is similar to FlexConnect as all traffic is terminated at the switchport and not tunneled back. Now there are some reasons why traffic would get tunneled, but I will not go through that here.

Would I invest in the 3850's... Yes, but also talk to your SE about the lower end switch that will support CA:) you can also do a hybrid setup with 3850's or the newer switch and a 5508 if you wish. The one thing to note is that the license will not transfer from a 5508 to any converged access controller unit acting as an MC. So if you decide to go with the 5508 and later want to go CA or replace the 5508 with a 5760, you will have to buy licenses.

I too would go with the 3600's or even the newer AP, if it does come out in time, but this depends on when your deployment is. ISE is not cheap and Prime is nice to have especially if you go to CA. I have clients that don't have Prime as its not needed to make your wireless work. It's really recommended if your using CA and with the newer version that will work we'll with ISE. With ISE, you need to spec out that correctly depending on how large of an environment you need to support and that's where it starts to cost. It's a good product though, just expensive.

thanks everyone

Scott, @ HQ lets say 5760/3850 deployed and remote offices got 2960 POE switch with 3600 series AP - will the remote office AP register to central HQ

Remote office connects to HQ over ipsec vpn

thanks

So with converged access, its design is really for access points to terminate on a 3850 or any CA compatible switch. There is a roadmap for a cheaper switch in the future. If you don't terminate an ap to a CA compatible switch, then the capwap will have to terminate onto the 5760/3850 that is acting as the Mobility Controller.

So lets not talk converged access. If you use a 5508 for example, you can use FlexConnect for your remote sites and determine what SSID's you want to terminate locally at the site and what SSID's you want to tunnel back through the VPN. So you have various choices, but in your design without a CA compatible switch, your capwap has to tunnel back to the MC.
