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?

Hi 

 

My pc obtain IP via dhcp from server 10.0.0.1

and working fine with the following setting 

IP 10.0.0.35

mask 255.255.254.0

gw 10.0.0.1

DNS1 10.0.0.1

dns2 8.8.8.8

Re: Aruba 2930F - can't ping from cli

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.

Re: Aruba 2930F - can't ping from cli

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

Re: Aruba 2930F - can't ping from cli

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
