Thanks for the quick response. I forgot to mention that the WAPs will be uplinked to switch ports, which should limit the subnet broadcasts. The only allowed devices connected to the WLAN are end user workstations (no servers or server applications) so we are anticipating that almost all traffic will be off the VLAN. Some incidental intra-VLAN traffic may occur as an end client maps a drive to another end client, but we expect this will be very limited.
In this network, end stations and servers reside on different VLANs and almost all traffic will be used to accessing e-mail servers and application servers on different VLANs.
Is there a solid solution for allowing end stations to seemlessly go from VLAN to VLAN without a noticeable loss of connectivity?
