You need to make sure the clients have a valid IP for their respective subnet.

You also need to include the default gateway in the client IP configuration. This default gateway must be the switch's IP on that subnet.

Please post the configuration from both switches along with the output from typing show vlan

sh vlan

111 HR active Fa0/11

172 Lab_172 active Fa0/17

interface FastEthernet0/11

switchport access vlan 111

switchport trunk encapsulation dot1q

interface FastEthernet0/17

switchport access vlan 172

switchport trunk encapsulation dot1q

interface Vlan111

ip address 111.111.111.111 255.0.0.0

interface Vlan172

ip address 172.168.10.1 255.255.0.0

now i can ping other when load the above configuration.

BTw, would like to confirm that. whether my step are correct or not? because i do use 2X network cables to line this 2 switch

eg

Switch A Switch B

Port fa0/1(L3)--as L3 link--Port fa0/1(L3)

Port fa0/24(L2)--crossover--Port fa0/24(L2)

Please advice whether am i using the right matter?

So, your original problem is now solved?

Let's see the port configuration from F0/1 and F0/24 on both switches.

By default, the switchport will be Layer2 and with that type of cabling design, F0/1 will be forwarding the inter-switch packets while F0/24 will be in blocking mode.

You have other options: L3 inter-switch links and etherchanneling.

Posting the configuration from those switchports can help us understand your design better.

yes, original problem resolved.

would like to know whether 2X cables will cause the network looping or not?

Based on the configuration posted, I don't foresee any loops.
