Hi Aman,

The debug shows src 10.86.10.1, dst 10.86.101.3...Are they on the same VLAN????From your configuration i dont think so...

Are you able to ping the gateway from the host? Verify if any antivirus or firewall is enabled on the host. If so trun off them and try pinging.

Hi Aman,

As Najaf suggested couple of things you need to check here:

1- Vlan 810 has the network 10.86.10.X also the DHCO pool is within the same network.

2- Check the ip address of the client which is on Vlan 810?( The client should have recieved the ip address 10.86.10.X network if he is getting something else then we have some problem here.

3- Provide us the ipconfig/all output from the client machine.

4- How did you got to know the ip address 10.86.101.3 ?

Regards

Inayath

i can ping the gatway from both the clintes , and ip config/all is the same as as DHCP , the problem here is can't ping the host wich is in same vlan , in debug ip icmp , its only showing ICMP reply , not showing ICMP echo request

InayathUlla Sharieff · ‎02-06-2013

Could you please paste the ipconfig /all output here ?

Regards

This host,

Does it have a software fw enabled on it? - if so make sure it allows incoming icmp traffic
