  • 1.  Cant ping Aruba controller from same subnet

    Posted Jul 03, 2022 09:35 AM


    I have a Aruba 7010 controller with multiple vlans configured, but for some reason i cant ping gateway (aruba controller) from one of the subnets.


    Vlan 100 /27 - works as expected

    New vlan 200 /26 

    If i configure dhcp on the switch connected to the controller i receive dhpc address but i cant ping anything from vlan 200 and ping from vlan 100 to 200 dosent work.

    When i remove dhcp configuration from the switch i can ping vlan 200 gateway from vlan 100

    The mask and gateway configuration for vlan 200 seems right on the dhcp server.

    I'm having a hard time understanding what IPs are on what devices and from which devices you are attempting to ping from. Are you able to sketch up a rough network diagram to show the topology and IP addressing so we can help more?

    I couldn't ping the controller from any new vlan I configured. But after restarting the controller, everything worked again.
