A user wants to allow VLANs 1-3967 on a pure Layer 2 FabricPath spine with the least amount of configuration required.
Which configuration is correct?
Click on the arrows to vote for the correct answerA. B. C. D.
Option B is the correct configuration to allow VLANs 1-3967 on a pure Layer 2 FabricPath spine with the least amount of configuration required.
A pure Layer 2 FabricPath spine provides Layer 2 forwarding and does not perform any Layer 3 routing. In order to allow VLANs 1-3967, we need to configure the spine to act as a Layer 2 switch.
Option A is incorrect because it only allows VLAN 3967 and does not include the range of VLANs from 1-3967. Additionally, the "mode fabricpath" command is used to configure FabricPath on the interface, not to allow VLANs.
Option C is incorrect for the same reasons as Option A. It only allows VLANs from 1-3967 but does not include the full range of VLANs.
Option D is incorrect because it is configuring FabricPath in transit mode, which is used for interconnecting FabricPath switches. This mode is not used for allowing VLANs on a pure Layer 2 FabricPath spine.
Therefore, Option B is the correct configuration because it allows all VLANs in the range of 1-3967 on the FabricPath spine. The "switchport mode trunk" command configures the interface to operate as a trunk, allowing multiple VLANs to pass through the interface. The "switchport trunk allowed vlan all" command allows all VLANs to pass through the trunk interface.
