Hello All,
Can someone please help me here to fix this port flap issue due to DTP-5-NONTRUNKPORTON.
I have a AccessPoint AIR-AP2802I-X-K9 connected to switch port GigabitEthernet4/32 with below switch port configuration:
!
interface GigabitEthernet4/32
description A0-AP06
switchport trunk allowed vlan 700,701,749
switchport trunk native vlan 700
switchport mode trunk
switchport nonegotiate
no logging event link-status
logging event trunk-status
spanning-tree portfast edge trunk
spanning-tree bpduguard enable
end
!
This Interface is flapping due to DTP-5-NONTRUNKPORTON
Below are the logs:
