Unable ping. Please help

Hello

We have a private network using 3com switches and tried to replace Catalyst Cisco 3750 switches, but we have the problem

2 switches and 3 VLANS
vlan10: Internale clients on port 1-8
switchport trunk native vlan 10

vlan 11: Linux RADIUS on port 19-21
switchport trunk native vlan 11

vlan 12: Remote firewall PCs on port 22-24
switchport trunk native vlan 12

Port 25 trunking to another switch
switchport trunk native vlan 10
switchport trunk allowed vlan 10-12
switchport mode trunk

vlan 10-12 on port 28: firewall CheckPoint
switchport mode Access
-----------------------------
The configuration is tested OK on the simulator GNS3.
When the cisco switches are replaced and the Remote firewall PCs are not able to ping the Linux RADIUS and firewall CheckPoint

When we connect a Windows Laptop on RADIUS and CheckPoint port, so the Remote firewall PCs are able to ping them

Why or something wrong on port 28 and 19-21??

Please help

Best regards

Tri

You need to provide more configuration details of all devices including IP addressing details plus a topology.
