hello, to everyone!
I have a wireless infrastructure with two 3com 8760 access points, a radius
server in an active directory domain. I configure the whole system to
permit wlan clients to authenticate using certificates and to be assigned
to a specific vlan using radius tunnel-pvt-group-id attribute.
everything works well when the client start association to any of the two
accesspoints. if the client roams from one accesspoint to another
everything continues to work.
when the client re-roams to the first accesspoint, a problem occours. in
particolar all the packets of the client that come out from the accesspoint
are tagged with the default vlan assigned to the SSID on the accesspoint,
instead of the tag transmitted from the radius server. in this way, the
client cannot communicate with its correct vlan, and his ip and gateway
aren't in the right vlan.
the two accesspoints have the last firmware and use IAPP protocol to
communicate.
can someone give me a possibile solution of the problem?
thank you
I discovered that the problem arises on 2.2.19 firmware but not in 2.2.4
firmware
