When I configure DHCP snooping on the
following topology, (see network diagram.pdf), Lan wired connection works
perfectly on Apple and Win7 machines.


When I do the test through wireless,
the Apple Machine does not get ip address and with windows it connects 
immediately
gets ip address, but it takes like 1 minute for windows to show that has a 
successful
connection even when you can browse and access the network.

  Now if I apply the trusted command on
the port of the switch where the WLC is connected to the LAN networks
everything works perfectly and the connection is instantaneous on both
operative sistems.

 

My questions should it be like that?  

 

To me it looks that if someone connects
to the wireless and enables a DHCPserver, using the Wireless adapter it can
generate a security issue because it will be broadcasting through the port 
connected
to the WLC in trusted mode.

 

Any comments would be appreciated
