Hi experts,

an issue on my c6500 sup720 12.2(33)SXI5.



I have two equal trunk configuration ports:



xxx#sh run int g8/45

interface GigabitEthernet8/45

switchport

 switchport trunk encapsulation dot1q

 switchport trunk allowed vlan 269

 switchport mode trunk

 logging event link-status

 logging event trunk-status

 load-interval 30

 spanning-tree portfast edge trunk



xxx#sh run int g9/27

interface GigabitEthernet9/27

switchport

 switchport trunk encapsulation dot1q

 switchport trunk allowed vlan 48

 switchport mode trunk

 logging event link-status

 logging event trunk-status

 load-interval 30

 udld port

 spanning-tree portfast edge trunk



Do you see any reason why using "show interface status" I see vlan 1
associated to g9/27 instead of trunk as for example of interface g8/45 ?



xxx#sh interface status

Port            Name                              Status       Vlan
     Duplex  Speed Type

Gi8/45       xxxx                            connected    trunk
full   1000 1000BaseT

Gi9/27       xxxx                             connected    1
  full   1000 1000BaseT



I see as well native vlan is not associated to gi9/27



xxx#sh interfaces trunk
