Aruba 3400 and Vlan tagging

Hi, I am using a 3400 controller and I would like to configure a trunk link between the 3400 and a Cisco switch.

An SSID is tunneled and assigned with a specific vlan and when I configure an access port between the 3400 and the Cisco , my laptop recieved an IP from a remote DHCP.

When both interfaces are configured as trunk with the same configuration I didn't recieve any IP and no trace of mac address on cisco switch.

My configuration are , vlan 81 is the vlan, even as native vlan it doesn't work

interface gigabitethernet 1/1
description "GE1/1"
trusted
trusted vlan 80-81
switchport mode trunk
switchport trunk native vlan 80
switchport trunk allowed vlan 80-81
no spanning-tree

 

interface Ethernet1/1/6
description FR-DC1-CTL-01_GE1/1
switchport trunk native vlan 80
switchport trunk allowed vlan 81

 

As access port on both side it works, so I have no more idea to fix it

Did you set your Cisco Trunk port to dot1q for its trunk encapsulation? .

Re: Aruba 3400 and Vlan tagging

Do you have switchport mode trunk on the cisco interface?

About the switchport  mode trunk I did it but as I didn't understand the behavior I reloaded the switch and now the vlan is working well, but maybe with all tests I performed the switch was in unstable state.

So sorry and thanks for your reply.
