A trunk link between two switches did not come up as expected. The configuration on Switch A is as follows:
Switch A# show running-config interface gigabitethernet1/0/1
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-10
switchport mode dynamic auto
no shutdown
The interface configuration on Switch B is as follows:
Switch B# show running-config interface gigabitethernet1/0/1 interface GigabitEthernet1/0/1 switchport trunk encapsulation dot1q switchport mode dynamic auto switchport access vlan 5 no shutdownAssuming the interfaces began with a default configuration before the commands were applied, which one of the following reasons is probably causing the problem?
- A.The two switches do not have matching switchport trunk allowed vlan commands.
- B.Neither switch has a native VLAN configured.
- C.Both switches are configured in the dynamic auto mode.
- D.Switch B is configured to use access VLAN 5.

Because the interfaces begin with their default configurations, each one uses native VLAN 1. Even though the interfaces are not configured with a consistent list of allowed VLANs, that will not prevent the trunk link from being negotiated. The real reason the trunk is not working is that both switches are configured with dynamic auto mode, causing neither switch to actively negotiate a trunk. Instead, each switch is waiting for the other one to ask for a trunk link. |
