I'm trying to fix the trunk port first. My port 25 is set as trunk and with the required tagged vlans. However I just cant ping to the core switch like the 3Com does.
Default route are same in both old and new switches.
3com Switch 4210
interface GigabitEthernet1/0/25
stp edged-port enable
port link-type trunk
port trunk permit vlan 1 11 to 17 100
HP ProCurve 2510
