ARUBA 2930F multiple IP adresses in one VLAN/Subnet

  • 1.  ARUBA 2930F multiple IP adresses in one VLAN/Subnet

    Hello,

    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.

    Specifically:
    On Cisco switch there is next configuration:
    interface Vlan 100
    ip address 192.168.100.1 255.255.255.0
    ip address 192.168.100.254 255.255.255.0 secondary
    ;
    When I try to configure the same on the Aruba 2930f:
    vlan 100
    ip address 192.168.100.1 255.255.255.0
    ip address 192.168.100.254 255.255.255.0
    error message after that.

    I tried to configure Loopback with IP address 192.168.100.254 - 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
      exit
    !
    vlan 20
      name "VLAN20"
      tagged 2,5-6,8,10,Trk2
      ip address 10.10.20.1 255.255.255.0
      vrrp vrid 10
        virtual-ip-address 10.10.20.254
        enable
        exit
    exit
