VLan issues

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?
Why can I see the switch from any location but not the device?

All other devices connected to other switches must be tagged with the same VLAN or have routes configured between the VLANs so that switch knows how to forward the request.
Is this device set with the proper subnet/gateway? Are you tagging the port the device is connected to with the appropriate VLAN tag?

The port that the device is plugged into is set as port access because it is to see only that vlan. Uplink on swtich and router are trunk port passing all vlans.

If my router can see the switch and the device and I can see the switch over the network why can I not see the device?

How about the first question. Does the device has the proper subnet/gateway?
Mohammed KhawajaManager - Infrastructure:  Information TechnologyCommented:
Even if you have a trunk port, you still have to define which VLANs you allow through the trunk as shown in an example for a Cisco device:

interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 2,10,20,30,50,60,100,999
 switchport mode trunk
 spanning-tree link-type point-to-point
 hold-queue 150 out
A diagram with the respective VLANs, Subnets, and addresses on it would be very helpful or the configurations.

From what you have described it sounds like you are having a basic routing issue. Usually in these cases either the device has a default gateway/subnet issue or there is no route to and/or from this subnet or your VLANs/networks are not configured properly.

Please add some of the above details so we can better assist you.
