  • 1.  AOS-CX - VLAN Switching

    Posted Jan 31, 2025 12:26 PM

    I am configuring a 6200F switch using aos-cx. The OS is ML.10.12.1040. I haven't used aos-cx previously. I am trying to configure inter-vlan switching. I have already assigned all my vlans an IP address and assigned the vlans to the appropriate interfaces.

    The physical interfaces have a "no routing" command in them. I have read that the physical interfaces don't support L3 routing. But if I go into an interface I see a "routing" command with the explanation of "Configure interface as L3". When I tried configuring the routing on the interface I got a "Configure system internal VLAN range before enabling routing". I then ran the command "system internal-vlan-range 1-500 confirm" and I got the message "One or more VLANs in this range are already in use."

    I am not sure how to proceed at this time. I want to be able to switch between vlans but I am confused as how to do it at this point.

    Thanks.

    all 6200 CX switches support L3 routing. you can assign interfaces as VLANs or make them a routing interface. when you assign the interfaces as VLANs as shown below, it will automatically route between them, in this case, it will route between 10.10.10.0/24 and 10.10.11.0/24 assuming the interfaces are up.

    interface 1/1/1
        no shutdown
        no routing
        vlan access 10

    interface 1/1/2
        no shutdown
        no routing
        vlan access 11
    !
    interface vlan 10
        ip address 10.10.10.1/24
    interface vlan 11
        ip address 10.10.11.1/24

    Thanks for the clarification and example.

    Here is an example of how I have configured one of my interfaces:

    Interface 1/1/1

        no shutdown
        no routing
        vlan trunk native 102
        vlan trunk allowed 102,110

    In one of your examples, you have the command: vlan access

    I am not using the "vlan access", should I be? What does the "vlan access" command do that the "vlan trunk allowed" doesn't do?

    Thanks.

    "Vlan access" simply defines the physical interface as an access interface(untagged). You are using trunked interfaces(tagged), which will work fine with routing between Vlan interfaces.
