    Posted Mar 16, 2017 09:39 AM

    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

     

    Regards

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

    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.
