"First and foremost, it should be clearly understood that 802.11b asset tags that transmit tag messages using Layer 2 multicasts (and do not attempt to associate to any WLANs) will not cause the initiation of any 802.11g protection modes under any circumstances. This includes asset tags operating in strict compliance with version 1 of the Cisco Compatible Extensions"
Hi,
ReplyDeleteI am working on a project where we have 3000 AP(LAP) and 24 controllers( WiSM) on 6500 switches,
all AP are acorss campus network, Now i need to configure AP grouping and 250 hosts per network only. i cannot use /22 subnet. all my subnet should be /24 only.
kindly let me know how to configure AP grouping with multiple clients subnets. i.e i want to know how to create 3 AP groups VLAN and 20 Client VLANs.
You could create AP groups according to the building the APs are physically located in. This would help you by logically grouping users based on geographic location & giving them an IP address where the third octet would be a number you'd logically assign to that physical building.
ReplyDeleteYour APs IP addresses do not need to be in the same subnet, so you can break up your AP vlan/ip scopes in any way you'd choose in order to make the broadcast domains manageable.
If you defined your AP groups by physical building, all the users associated to APs in those buildings would be in the same subnet.
If all your users are in the same physical building that has 3000 APs, you could assign your users to a vlan based up on an active directory group membership (if this is available on this network).
If all the APs are in the same physical building, you might break down the building into zones, wings or groups of floors (floors 11-14 for example) to define your AP groups and user subnets.
Do you know how many users you're anticipating being associated at any given time? It might be less than you'd think.
