What type of server are you guys using ? Is it load balanced ? 50/50 or 100% ?
Cisco Registrar, 100%. Upgrading to new version soon though, and hopefully we will be using what I think Cisco calls
"one-lease-per-client" by using Mac-address for client identifier. On this current version for some reason we could not do it (I am not the DHCP admin), and we had a couple of mis-behaving users eating up a ton of IPs, depleting a particular subnet on the pool. And since the vlan pooling algorithm happens before a client requests an IP, clients were still placed on this subnet with no IPs left. The mis-behaving client was basically requesting IPs and declining them. Both times Mac OS X machines.
Are you guys using /22 , /23 ?
/24 for public ip subnets, and /22 for private IP subnets.
Lease time ?
We played with this a lot, and decided on 30 minutes.
How many wireless users ?
7000 simultaneous, about 10-12 unique
Using VLAN pooling hash or even ?
hash
IPv6 ?
Not yet..
Ryan, 42k concurrent users? wow!
