I have an a switch 3560 with IOS c3560-ipbase-mz.122-35 where from port fa 0/1 until port fa 0/22 thera are connected
22 AP Cisco 1242.
On this ports I have configured only "switchport access vlan 3", which is vlan for wi-fi.
Yesterday, for each of this ports I have found:
switchport mode trunk
switchport trunk encapsulation dot1q
mls qos trust cos
auto qos voip trust
spanning-tree bpduguard enable
and was impossible reach AP and my guest could not surf on Internet.
What can be happen ?
Why did switch change configuration ?
