We go through the same procedure Bittu outlined above on *every* install, which is a bit time consuming. Since we also use a VLAN for network management, say 10 for arguments sake:
1. Plug in fresh ZoneDirector on switchport with VLAN 10 *untagged* (HP) or *native* (Cisco)
2. Configure ZoneDirector, change VLAN to 10.
3. Reconfigure switchport to VLAN 10 *tagged* or move ZoneDirector to apprpriately tagged switchport.
4. Configure the "Access Point Policy" to use VLAN 10 for management.
For access points, similar procedure:
1. Plug in access point on switchport with VLAN 10 *untagged*.
2. After the access point is accepted and configured, it will disconnect.
3. Wait an appropriate amount of time before connecting the access point to a tagged port *or* tagging the port it is connected to. (This step is a bit hair raising because you lose visibility once the access point resets for the first time, and you don't know what it's doing, especially if you're doing a deployment with remote hands without central staging.)
4. If you manage to get the timing right and you don't disconnect the access point in the middle of a firmware update, congratulations, the AP should be online.
5. Rinse and repeat 1-4 a few hundred times. :-)
I am sure there would be an easier way to do this using RADIUS, NAC, and GVRP but since we do a lot of small to medium sized networks (10 - 250 APs) it is not something that we have really investigated.
Is there an easier way?
