I have a strange issue, I hope someone can help. I hope I can explain it well enough.
I have a 4500 3com switch that I created a vlan and a vlan interface on. The switch has one port associated to the vlan as port access. I have a device plugged into that port and the device has a static ip with subnet and gateway set.
The 4500 switch connects directly to my router which is a 3Com 5500 switch by fiber. The uplinks are set as trunk ports. I have same vlan set on 5500 with an interface set as the gateway for this vlan. I also have the OSPF route set for the vlan.
The issue is; I can ping the switch and the device from the 4500 switch and the 5500 router, but I cannot ping the device from any other switch at that location or over my network. I can ping the interface on the 4500 switch from any location, but I cannot ping the device.

Why can I see the device from the router but not over the network?
