  • 1.  No ping gateway Aruba 2930M-24G

    Posted Sep 27, 2021 09:00 AM
    Hello,

    I have a very big problem, the gateway of all vlan is off (no ping, not un arp...), when I connect a client directly in firewall : ping ok, arp ok, internet ok.
    When I plug ma switch on this, no ping, no arp...

    My config : (test on port 1/4 in supervision vlan, no ping and arp on my gateway 172.16.40.2).
    Thx for your help :)
    Running configuration:

    Your test client is plugged in to port 1/4 which is on VLAN1, not the SUPERVISION vlan.  You mentioned a firewall, is that connected to this switch?  Which switch port is it connected to and what vlans are configured on the firewall?  When you're pinging from your test client are you attempting to ping the switch or the firewall?

    Hi, from the configuration you posted your Aruba 2930M backplane stack has only the (default) VLAN 1 - with no IP address configured - configured and IP Routing is not enabled, it means that you stack is/must be connected to some "other device" acting as the IP Router for your network and this "interconnection" is performing at Layer 2 level (so there should be an uplink interface to that "other device" carrying necessary/required VLAN).

    Given that, the Routing and the VLAN membership are managed by this "other device"...the only thing we can understand is that the Next Hop Gateway for this switch is 172.16.40.2 ("ip default-gateway 172.16.40.2" <- Your Firewall?) but the Switch itself HAS NO (compatible) IP address configured on that VLAN 1.

    I'm under the impression that few bits were lost in setting this up or that the whole picture (picture we can't guess) is a little bit more complex and require details you didn't gave us...at the point that you can't simply just connect a Switch to an existing network/firewall and to hope it works "as-is".
