Dear all,
I have a 5508 WLC and i am configuring it to support for wireless Vlans, i have configured the vlans on the core switch, then i have connected the WLC to the core switch using two cables, and enabled LAG.
I have also configured an interface for every vlan that i have and a wireless SSID for the interfaces.
the controller is directly connected to the core switch (6500), and the LAG seems to work fine.
the LAG configuration is:
int port-channel 5
switchport
switchport trunk encaps dot1q
switchport mode trunk
interface g1/1/2
switchport
switchport trunk encap dot1q
switchport mode trunk
channel-group 5 mode on
Show lag summary on the controller is : LAG enabled.
now i have a management interface, interface vlan tag is 2.
and the SSID's can be seen as broadcasted, now when i connect to a wireless SSID i cant ping the gateway, but when i connect to the management interface SSID everything is fine.
also when i connect to another SSID, and give it an IP address from the management subnet i also can ping everything.
but when i give my LapTop an IP from the Wireless vlan subnet that should take i cannot ping anything even the gateway.
any idea.
thanx in advance

another note
the AP interface is configured as:
int g1/0/2
switchport mode trunk
switchport trunk native vlan 2
speed 100
duplex full

The AP's do not need to be in a trunk port just an access port unless they are in h-reap mode. Make sure that you only allow the vlans you have on the wlc defined on the trunk port. Also make sure you are not routing the service port. The service port and the management ip of the wlc should not be able to communicate.
Thanks,

Dear Scott,
thanx alot for your reply.
i have canged the port that is connected to the AP to:
int g1/1/2
switchport mode access
switchport access vlan 2
i am not running H-Reap, also the AP are joined to the controller through the management interface and i didn't configure the Service-port.
still cannot ping vlan gateway unless i give my device an ip from the managenet vlan subnet.

it seems that i have forgot to assign the wireless interface to the created Wlan.
it is now working, finally.
thanks scott

one other thing.... I wouldn't hard set the speed and duplex on the AP unless you also configure it on the AP. I just noticed that when you had it set as a trunk.

i have just set the speed and duplexity because the AP interface is fastethernet and the switch that is connected to is gig ethernet.
and it cannot be seen as a cdp neighbor unless you modify the speed, but no clear reason of the duplexity :-)

What VLAN are you putting the clients on? If you do a show vlan brief on the switch, do you see that vlan created? If you connect a wired device in the 'wireless clients' VLAN, can you ping and get to the internet?
