hi, group

  I connect a Cat3750 and Cat2950 with one RJ45 cable.
Next error occured.
SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non
trunk [chars]
[chars].
I don't set anything one Cat2950.For the Cat3750's
interface, I input the command below:

interface GigabitEthernet1/0/11
 description " Access 192.168.45.0/24 NW "
 switchport access vlan 45
 no ip address
 duplex full
 speed 100
 no mdix auto

Why the error happened? Why they couldn't negotiate it?
