look at your core switch configuration - you should see entries for VLAN's,
trunk ports and encapsulation - on our Cat4003 I can do a 'sh port' to see
this detail.

below is an example of the output, here you can see port 2/1 is the trunk
port on fibre, ports 2/4 and 2/5 are trunks on cat5, port 2/2 is on vlan 1,
all other ports are on vlan 7.

Port Status Vlan Level Duplex Speed Type
----- ---------- ---------- ------ ------ ----- ------------
 2/1 connected trunk normal full 1000 1000-LX/LH
 2/2 notconnect 1 normal full 1000 1000BaseSX
 2/3 connected 7 normal a-full a-100 10/100BaseTX
 2/4 connected trunk normal a-full a-100 10/100BaseTX
 2/5 connected trunk normal a-full a-100 10/100BaseTX
 2/6 notconnect 7 normal auto auto 10/100BaseTX
 2/7 connected 7 normal a-half a-10 10/100BaseTX
 2/8 notconnect 7 normal auto auto 10/100BaseTX
 2/9 notconnect 7 normal auto auto 10/100BaseTX
