Hello,
I have a Nexus 5672Up and want to trunk a C3560X.
I have configured on Nexus:
interface Ethernet100/1/14
switchport trunk allowed vlan 990
spanning-tree port type edge
spanning-tree guard none
and on 3560X:
interface GigabitEthernet0/46
switchport trunk encapsulation dot1q
switchport trunk native vlan 990
switchport trunk allowed vlan 990
switchport mode trunk
spanning-tree portfast
spanning-tree bpduguard disable
spanning-tree guard none
The port on Nexus is all the time on disable with the following logging:
