I accidentally trunked an access port.
I was configuring an AP and trunked interface 46 instead of interface 45 on a cisco switch.
I received a call from the building across the street saying there network went down.
What happens if you trunk an access port?
Was changed to
interface FastEthernet0/46
description ap-lobby
switchport access vlan 999
switchport trunk encapsulation dot1q - ******Command I added on accident ****
switchport mode trunk - **** Command I added on accident ****
speed 100
duplex full
When I removed the two commands above their IP Phone and Desktops seem to be back online but for some reason two users are still not getting a DHCP address and nervous I screwed something up badly. VLAN 999 I believe connection between several buildings in the city , a Metro Ethernet connection I think. New to company so learning the topology of our network.

I have an understanding of access and trunk ports. What I don't understand is the effect it would have on the Network if I made this change. As the Interface I changed was connected to the switch at the other building and curious if it could have somehow filtered to other building as well. I believe the effect was only between the two building but not 100% sure. I am confused as to why there are still some desktops which I can't back online for some reason.
I do have the backup configs but not ready to apply then as the change I made might not have been severe enough, this is why I posted this question to get an understand of what my change may have done, could it have been severe?
