Hi all:
CISCO6509#show vlan id 123
VLAN Name Status Ports
---- -------------------------------- ---------
-------------------------------
123 CISCO3750 active Po200, Po64----------------------------------------------------------------------------------------------
I only issued the "switchport trunk allowed vlan 123" on Po64, not on Po200. but when I "show vlan id" as above, It said both Po200, Po64 allowed vlan 123. Are there any reason causing this problem?
----------------------------------------------------------------------------------------------------------------------------- interface Port-channel64 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 123 switchport mode trunk switchport nonegotiate no ip address end
interface Port-channel200 switchport switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate no ip address end
