    Hi Folks 

     

    Few days ago i bought Aruba 2930F and I have a problem I'm not able to ping host in internet exp cnn.com from switch CLI

     

    PC connected to vlan 2 untagged port can ping internet host without any problem 

    Switch is rechable prom subnet 10.0.0.0/23

     

     

    See config below:

    timesync ntp
    ntp server 158.75.5.245
    ntp enable
    time timezone 60
    ip default-gateway 10.0.0.1
    ip dns server-address priority 1 8.8.8.8

    interface 48
    name "TRUNK_IN"
    exit
    snmp-server community "public" unrestricted
    vlan 1
    name "DEFAULT_VLAN"
    no untagged 38-47
    untagged 1-37,49-52
    tagged Trk1
    no ip address
    exit

     

    vlan 2

    Hi,

     

    Does your PC gets an IP address from DHCP server? If so can you verify what the IP information (IP address, subnet, default gateway) the PC receives?

    Thank you very much. My feeling is that you also have ip routing enables but I can't see the config. This is not a problem but can you remove the ip default-gateway configuration line and add the following:

    ip route 0.0.0.0 0.0.0.0 <default gateway IP>
    ip routing (but think you have this already enabled)

     

    Now you can test again but think this will work. 

     

    Regards, dobias

    if your switch can ping aother l3 devices on same segments , but cant ping to behind to your GW - it must be routing issue .
    From your switch to your GW , are u able to ping via CLI?

    Please share with us full switch config , and also output of traceroute to diffrent internet ips

    Hi again 

     

    I agree that seems to be routing releated 

     

    I'm able to ping my switch from Aruba(10.0.0.249) - to GW(10.0.0.1) and from GW to Aruba.

    Traceroute ands with timeout tracert.JPG

    any other device connected to the same network are able to ping host in internet without any problems.

     

    I noticed that ICMP packet from Aruba lenght is 60 from other host 74
