    To whom it may concern,

     

    Not sure what I'm doing wrong here but I can't seem to ping any of my default gateways I tend to connect my laptop to. For instance, If I'm on Vlan 2 and I ping Vlan 202 (172.20.2.2) i Cannot reach it. I have ip routing enabled yet it doesn't seem to want to work. However, from the Aruba I can ping anything I want. Firewall is disabled on my laptop. Here is the config.

    Running configuration:

    Please assist. I erase startup config and dropped in the config but it still didn't make a difference. I could try to reinstall the firware but I'm hoping I don't have to reboot the switch again since the site is active. 

    Thank you in advance

    Do you have static IP assignment on the other vlans than VLAN1?

    When in one of the VLANs, can you ping the switch IP for the same VLAN?

    Can you ping a switch IP in another VLAN?

    Do you see the ARP entries in the switch for your clients? Do you see the ARP entries for the switch IP in your client?

    If your default gateways are not the switch IP addresses, do you have a route back from your routers/gateways for the IP addresses you assigned to the VLANs pointing to your switch?

     

    Probably easiest to find someone to troubleshoot together, like your reseller/partner, or Aruba Support.
