VLAN 1 Line Protocol Down

i have an older 3560 switch that I am planning to test a RADIUS solution on.  I configured the device with VLAN 1 and an IP address.  Int fa0/8 is connected and in VLAN 1.
I get the following errors:
*Mar  1 00:00:43.427: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/8 VLAN1.
*Mar  1 00:00:43.427: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/8 on VLAN0001. Inconsistent port type.
*Mar  1 00:00:43.427: %LINK-3-UPDOWN: Interface FastEthernet0/8, changed state to up
*Mar  1 00:00:44.434: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/8, changed state to up
This is a simple configuration and need the switch to be able to ping the RADIUS server.  

The config is attached.

Is fastethernet 08 connected to another switch?

In the config it is designated as access meaning it is only useable for a host.

Yes, a Cisco 2960.

When I try to change it to a trunk port I get this message.
Switch(config-if)#switchport mode trunk
Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
Configured the following.
Switch(config-if)#switchport trunk encapsulation dot1q
Sounds good, errors resolved?
Everything works.  Thanks so much.
thanks Patrick.  Haven't done this in some time.  But it came back to me when I got the command rejected error.
Nice! Glad to be off assistance.
