Do y'all have one vlan per building? We do not have VLans per building for our Wireless clients. We do have VLans per building for our wired client network.
How large are you DHCP pools? Here at the College we have 3 Vlans ( /19 in a pool) for our secure SSID and 12 VLans ( /24 in a pool) for our Open Guest SSID. What is the pool expiration time? The Secure and Guest network has a 2 hour dhcp lease time. I am thinking about reducing the Guest lease down to 1 hour. Do you allow roaming over entire campus, per building or what? We allow roaming on all our campuses How do y'all find these abusers? We use a combination of firewalls and intrusion detection. All the logs are also searchable via Splunk. We are also looking at a WildPackets (now known as Savvius) Omnipliance CX to do in-depth packet analysis on the fly and historical as well.

Some buildings have their own vlan while others do not. Each year we have more devices and thus our DHCP pools are stressed. We are looking at changing our network design and giving each building their own vlan and larger DHCP pools. We currently have a class B IPV4 internet addresses and will move to NAT. When students are abusing copyright etc. we are given an IP address and asked to determine who is doing the abusing. As students roam they could end up with multiple IP addresses and Natting will complicate the ability to find these abusers I am curious about the following. Do y'all have one vlan per building? How large are you DHCP pools? What is the pool expiration time? Do you allow roaming over entire campus, per building or what? How do y'all find these abusers? Any thoughts will be appreciated. -Jeff Legge Radford University 540-250-5224 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
