ARUBA 2930F multiple IP adresses in one VLAN/Subnet

    I have an issue with configuring Aruba 2930f switch.

    Im changing Cisco switch to Aruba switch and I need to configure 2 Ip adresses in same VLAN and Subnet, but I cant do this due to error.

    On Cisco switch there is next configuration:
    interface Vlan 100
    ip address
    ip address secondary
    When I try to configure the same on the Aruba 2930f:
    vlan 100
    ip address
    ip address
    error message after that.

    I tried to configure Loopback with IP address - same error.

    Please help with this issue. In general, is this possible on Aruba switches?

    you can use the VRRP trick for the switch to respond to both of the IP address that is on the same subnet.

    ip routing
    router vrrp
      ipv4 enable
    vlan 20
      name "VLAN20"
      tagged 2,5-6,8,10,Trk2
      ip address
      vrrp vrid 10
