    Hey Airheads,

    hopefully this is the right community to ask that question.

    I'm curently trying to configure a new edge switch (Aruba 6100 12G CL4 - Layer 2) in our environment.
    All our edge switches are managened in a seperate vlan, where only admins can access.
    So I added a vlan (vlan20) on the switch and gave it an ip address (#conf, #interface vlan 20, #ip address 172.21.16.240/24). The problem now is that the switch has no connection to Aruba Central anymore because it can't access the internet without the gateway 172.21.16.254.
    So my question is if there is any posibility to change the managament vlan from vlan1 to my vlan20 and set up a default gateway? We never use the default vlan1 and always manage them through vlan20.

    I already tried to turn dhcp on on vlan20 to check if that would word but it seems its only possible for defaut vlan.

    Many many thanks for your help!
    Cheers,
    Yannik

    simply use the 

    ip route 0.0.0.0/0 172.21.16.254  

    The above will give you a default gateway to your host on VLAN 20

    Note to use 6100 in central you will need 10.07 software release  which is now available on ASP as of today.
    Also only template group will be supported in current central version (2.5.3)  

    dhcp only supported on default vlan 1 on 6100

    I hope this helps

    basic config

    vlan 20
    !

    int X/Y/Z
    no shut
    vlan access 20
    !
    int vlan 20
    ip address 172.21.16.X/24
    ip route 0.0.0.0/0 172.21.16.254
    !
    ip dns server-address A.D.C.D
