VLAN tagging between AOS and AOS-CX

  • 1.  VLAN tagging between AOS and AOS-CX

    Posted Nov 14, 2022 12:35 PM
    Hello,

    I hope someone can help me.
    I have the following problem:
    Aruba 2540-48G-PoE+ 4SFP+ Switch and I wants to connect it with a Aruba CX 6000 12G PoE+ Switch.
    It works fine as long as there is no vlan tagging, which is needed.

    How can I connect multiple VLANs between AOS und AOS-CX?

    On 2540 I configure VLAN 1,48,50 as tagged.
    On CX6000 I configure VLAN trunk allow 1,48,50 with VLAN 1 as native vlan.

    But there is no communication between the switches.

    Hi Haensen87,

    On the 2540 you tagged vlan 1 where this the pvid vlan (what is untagged) on the CX6000.

    Did you enable the interface on the CX6000? Is the interface up?

    Example:
    interface 1/1/1
no shutdown
no routing
description "link_to_link"
vlan trunk native 1
vlan trunk allowed 1,48,50
exit​

    What do you have on 2540 when use command :

    show port X detail

    ------------------------------
    PowerArubaSW : Powershell Module to use Aruba Switch API for Vlan, VlanPorts, LACP, LLDP...

    PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...)

    PowerArubaCL: Powershell Module to use Aruba Central

    PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)..

    the command is

    show interface <number>

    and i get information for name, link status, mac address, total send/received packages and errors

    @mkk: yes the port on cx6000 is enabled like every port in default configuration in lower cx series
    I already enter the commands you send.

    On Aruba 2540 you can't find information for pvid, I guess it is the default VLAN, which is by default VLAN 1.

    When I configure the connection with just "vlan access 1" everything works fine, but I need additional vlans on the CX Switch.

    I can try next week some things when I'm back at customers site.

    Perhaps adding the value `tag` after defining the native vlan? Like so:
    interface 1/1/1
    no shutdown
    no routing
    vlan trunk native 1 tag
    vlan trunk allowed 1,48,50
    exit

    Thanks to Tiffany.Chiapuzio-Wong the value "tag" helped.
    Now everything works as I wished.
