How to configure a management VLAN

  • 1.  How to configure a management VLAN

    Posted Oct 19, 2023 11:03 AM

    Hello,

    we have some 6100 and 6200F switches centrally managed by Aruba Central, and we would like to add them to our management VLAN so that nobody except authorized personnel can access them via HTTPS, via SSH or via any other way, but we're facing several issues. Do you have a best practice about that, please?

    What we tried:

    • We cannot use mgmt VRF on 6100 since it's not available
    • We gave static IP address to the switch at mgmt VLAN level, but we cannot set the gateway. We tried to do that at sttic route level, but it doesn't work
    • We tried to set the source interface, but still no effect

    Most of the times, the switch goes offline and we need to zeroing it and restart from scratch, so we must be missing something.

    Thank you if anyone of you has a clue!

    Bye,
    Luca

    Howdy! 

    I had the same/similar issue. With AOS-CX you need to put a ACL for the mgmt vlan on the default VRF. See below to see my configuration:

    ntp server pool.ntp.org minpoll 4 maxpoll 4 iburst

  • 3.  RE: How to configure a management VLAN

    Posted Oct 23, 2023 03:15 AM

    Hi MojoPBS,

    thanks for your reply. We've figured out how to assign a static IP only to mgmt VLAN, removing the one from VLAN 1: out error was that we were setting static routes at device level rather than at group level. The assignement at device level made the switch to become unreacheable when we disabled DHCP from VLAN 1, while assigning at group level made the job.

    Thank you,
    Luca
