Aruba Central offline devices after creating DHCP-Server

  • 1.  Aruba Central offline devices after creating DHCP-Server

    Posted Jun 28, 2018 02:49 PM

    Hello,

     

    today I have a question about offline IAP AccessPoints in Aruba Central. Yesterday I configured in the Central Webinterface a new local DHCP Server for the MGMT-Network.

     

    After creating all APs are offline in Central but the function of Wireless Network is working well.

     

    HTTPS://ARUBA-VC is not answering, SSH is OK

     

    so first test was 

    ping www.google.de
    no host www.google.de found

    IP-Address same story

    Routing-Table

    AP-09# sh ip route
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
    0.0.0.0         10.49.0.1       0.0.0.0         UG        0 0          0 br0
    10.49.0.0       0.0.0.0         255.255.255.0   U         0 0          0 br0
    10.49.3.0       0.0.0.0         255.255.255.0   U         0 0          0 br0
    172.31.98.0     0.0.0.0         255.255.254.0   U         0 0          0 br0

     

    I don´t know what is wrong in my configuration, at last creating dhcp-server

     

    so for testing, I want to delete the dhcp-server but I can only connect via ssh.

     

    my question is how can I delete the dhcp-server for my mgmt-network?

     

    I don´t understand why I cannot ping internet clients. on my switches on the same subnet is ping www.google.de oder IP-Address OK

     

    Greetings from Germany

    documentation on https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c05320370 you can find

     

    DHCP-Server

     

    Local—In this mode, the Virtual Controller acts as both the DHCP Server and the default gateway. The
    configured subnet and the corresponding DHCP scope are independent of subnets configured in other IAP
    clusters. The Virtual Controller assigns an IP address from a local subnet and forwards traffic to both
    corporate and non-corporate destinations. The network address is translated appropriately and the
    packet is forwarded through the IPSec tunnel or through the uplink. This DHCP assignment mode is used
    for the NAT forwarding mode.

    I don´t understand how can i delete the dhcp-server on cli

    you can delete DHCP Scope with

    no ip dhcp "profile name"

    my mistake was that the profile name was not correct

     

    the profile name is given with

     

    show running-config
    
    .......
    
    ip dhcp profile name
     server-type Local
     server-vlan xxx
     subnet xxx
     subnet-mask xxx
     default-router xxx
     dns-server xxx
    
    ......
