Wireless Access

Hello everyone 

 

I have Aruba3600 controller connected to core-switch, I have followed the procedure defining vlans, gateway,licenses, trunk/access ports ...etc.

 

I've connected the trunk port from Aruba controller to tagged port in the same vlan on core-switch

when I ping the gateway from Aruba controller or ping the aruba controller ip from core-switch I got unrechablity message on both

if I connect from Aruba to core-switch with access port it will be pingable but on trunk port not 

 

on the following screenshot I am trying to trace the gateway (10.18.1.1) from aruba controller (10.18.1.10)

Aruba controller is on the same subnet.

 

also I've got a CDATA error as in the screenshot and I don't know why ! I have inserted the license already in the aruba and tried 2 firmware versions (3.3 and 6.2)

 

 

 

 

any hint please, thanks in advanced

 

Regards

did you reboot after adding the licenses?

yes more than one time 

Okay.  The licenses have nothing to do with the trunk.  Is the native VLAN on the Cisco side the same as the native VLAN on the Aruba side?  Please post the configuration for both sides.

In addition to cjoseph suggestions make sure of the following :
- VLANs are trusted
- your default gateway : show IP default-gateway or show IP route

maybe I didn't explain well :) :

. I mentioned the license just because I read here about this error "role authenticated is unknow" related to license .
. For both sides configurations:

On the Aruba side, what is the output of "show trunk"? What is the Cisco side of the configuration?

on the Brocade Switch it is connected to Vlan 18 through TAGGED port (ethernet 1/7)as a trunk port bettween aruba and the core-switch

all thanks for Mr. cjoseph and Mr. victorfabianall  :)

solution was to put any other vlan than 18 as a native

Wait: on the Aruba side Vlan 18 is the native vlan, but on the Cisco side it is tagged? Both sides have to match: both sides have to have vlan 18 as native or untagged or both sides need to have it tagged and allowed...
