Hello,

I do not see any problem in the configuration. This switch is only connected to one switch. Is that right? Please follow my previous comment. Try to isolate the issue. Disconnect most of the hosts in downtime and try to ping again.

Lets wait for others feedback also. I do not think the confuration has any problem. The problem must be in the network.

What is the result when you ping 107.107.21.88? Do you have timeout?

Create interface vlan 3 in 2960x with an IP address in the range of your client and try to ping the IP address from one of the client connected to it. 

Sometimes, a faulty cable or virus in the network can cause timeout problem. Do you have issue when you ping from one client connected to 2960x to another client connected to the same switch?

Please remove password and snmp from your text configuration attached.

Hello,

Do you have any problem when traffic is passing through the switch(switching)? Ping the ip address of L2 switches is usually handled by processor. If a large amount of traffic is imposed dirrectly to the switch, it may affect its function. Sometimes, the issue might be inside the network. In downtime, remove all switch connections except one PC and ping the switch. If you do not see that problem with one PC, try to install a wireshark and check your network traffic.

Hope it helps,

Masoud
