Hello Igli
At first glance I can’t say that I find something wrong with the information you have sent. One thing I do find unusual, although this should not cause a problem, is the fact that you are using VLAN 10 as the native VLAN on the trunk. You may want to change that and make VLAN 10 a tagged VLAN across the trunk. Secondly, just keep in mind that in order for the two hosts to communicate, no default gateway is necessary.
Even if this is not the issue, I suggest you work your way through the problem like so:
- Create an SVI for VLAN 10 on both switches, and use another address for these within the subnet, say 10.10.10.52 for SW2 and 10.10.10.53 for SW3. Try to ping 10.10.10.52 from host A and then 10.10.10.53 from host A. This way you can see if the problem is local to the host, local to the switch, or if the problem is on the trunk.
- Try pinging one SVI from the SVI of the other switch to see that the packets on VLAN 10 are indeed traversing the trunk.
- Then you can focus on troubleshooting either the trunk or the hosts themselves.
Hopefully this will give you a good start. Please share your results with us!
I hope this has been helpful!
