  • 1.  Aruba CX on Eve-NG - Routing between Vlan

    Posted Apr 08, 2025 04:30 PM

    Hi

    befaore going to prod, i'm testing virtual onvironment on Eve-NG, and manage to make Aruba CX works.

    not used to CX cli command, we have 2930f aruba on our network more convinient to setup (web ihm or menu command)

    anyway

    i have 4 aruba nodes
    CORE have 4 vlan configured, each on having his own ip address
    * vlan 10 SITEA 192.168.10.1/24
    * vlan 20 SITEB 192.168.20.1/24
    * vlan 30 SITEC 192.168.30.1/24

    CORE 1/1/1/ is connected to SITEA on 1/1/1
    CORE 1/1/2 is connected to SITEB on 1/1/1
    SITEC 1/1/1 is connected so SITEB on 1/1/2

    port 1/1/1 is trunk vlan 10
    port 1/1/2 is trunk vlan 20 and 30

    SITEA has VLAN 10 configured with IP 192.168.10.2/24
    port 1/1/1 trunk vlan 10

    SITEB has VLAN 20 configured with IP 192.168.20.2/24
    * have VLAN 30 configured (no address)
    port 1/1/1 trunk vlan 20 and 30
    port 1/1/2 trunk vlan 30

    SITEC has VLAN 30 configured with IP 192.168.30.2/24
    port 1/1/1 trunk vlan 30
    + dhcp server range 192.168.30.10-100/24, default-router 192.168.30.1

    with all this
    SITEC can ping CORE on 192.168.30.1
    SITEB can ping CORE on 192.168.20.1
    SITEA can ping CORE on 192.168.10.1

    Now i'd like to enable routing between vlan, but can't figure out how.
    for now, from SITEC 192.168.30.1 i can't ping 192.168.10.1 for example.

    what did i miss ?
    to configure interface, i had to use command : no routing, otherwise i could set trunk/access vlan on them, is it because of this ?

    Hi,

    Here is a config snippet for the core. The eve-ng aos-cx switch has routed interfaces (no SVI support by default) enabled by default but not all aos-cx support that like the AOS-CX 6200 for example. If you have a 6200 you don´t need the "no routing" command on the interface.

    The vlan trunk allowed command tells you which vlans that are allowed on the port. In the example you can see that the native (untagged) VLAN 1 is not allowed so untagged traffic from VLAN 1 will not go through, only tagged VLAN traffic from vlan 10 on int 1/1/1.

    vlan 10,20,30
    interface 1/1/1
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed 10
    interface 1/1/2                                                
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed 20,30
    interface vlan 10
        ip address 192.168.10.1/24
    interface vlan 20
        ip address 192.168.20.1/24
    interface vlan 30
        ip address 192.168.30.1/24

    I don't believe 2930F is a cx switch. I believe it's AOS. 

    Under config t do the " ip routing" command.
