Refer to the exhibit. You are verifying connectivity within a leaf device. You attempt to connect to a destination server in VLAN 17, and you then run the show mac address-table command as shown. Why does the show mac address-table output show a different VLAN?

Question

Accepted Answer

C. The VLAN ID shown is used for identification and internal mapping within the ACI leaf In Cisco ACI, external VLANs (like VLAN 17) are often mapped to internal VLANs or VXLAN Network Identifiers (VNIs) for forwarding traffic within the fabric. The show mac address-table command on a leaf switch may display these internal identifiers rather than the original external VLAN ID.

Answer

A. The wrong AEP is attached to the leaf ports An incorrect AEP (Attachable Access Entity Profile) would likely result in no connectivity or traffic being dropped, not a different VLAN appearing in the MAC address table.

Answer

B. The VLAN configuration on the leaf switch is incorrect While incorrect VLAN configuration could cause issues, the question implies traffic is seen, and the display of a different VLAN is a characteristic of ACI's internal mapping, not necessarily an incorrect configuration.

Answer

D. When traffic appears, the Cisco ACI marks ports with VLAN 17 ACI does not mark ports with the external VLAN ID (VLAN 17) when traffic appears; rather, it uses internal encapsulation for fabric forwarding.
