Our wireless system has grown from a few dozen users and access points to thousands of users and hundreds of access points. I think there are some things we would have done differently if we knew then what we know now. Aruba’s VRD documents are helpful but I’m posting this as a way to check in with the community and solicit opinions from folks with similar production networks.
1. We have a physically redundant layer 2 master/local controller architecture and a reliable wired network out to the APs
2. Access points are deployed on the access vlans
3. Authenticated users are on one vlan built of many /24’s
4. Guest users are on one vlan built of one /22
5. We are not using vlan pools or mobility
6. All IP addressing comes from enterprise DHCP servers
Right now we are re-working some of our network and I have a chance to re-implement how we use vlans and subnets within our wireless system. I'm not looking to make work but I would be glad to improve things. Anybody willing to chat about what works for you?
Thanks,
Troy
