What additional options do you specify when doing extended ping? It could be that the destination does not have a route back to the default source IP, but does to the IP address used in the extended ping.

Thanks for the response

I used extended ping and sources address is the one of the ip address of the switch(vlan interface IP) and destination ip

is ip of the detination server

Then the default source address for the ping must either not be allowed to get to the destination, or the destination does not have a route back to that address. You could use a sniffer to confirm where the traffic is being dropped.
