350-601 Network Practice Question
Which command is used on a Cisco Nexus switch to display the VXLAN network identifier (VNI) associated with a specific VLAN?
⚠ Common exam trap
Cisco often tests the distinction between commands that show VXLAN configuration versus operational state, and the trap here is that candidates confuse 'show interface nve 1' (which shows VNI membership on the NVE) with the command that specifically maps a VLAN to its VNI, leading them to select option C instead of the correct 'show vxlan vni'.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show vxlan vni
The 'show vxlan vni' command on Cisco Nexus switches displays the VXLAN network identifier (VNI) and its mapping to VLANs, including the associated VLAN ID and segment state. This command directly answers the question by showing the VNI-to-VLAN binding, which is essential for verifying VXLAN overlay configurations.
Answer analysis
Option-by-option breakdown

- ✓
show vxlan vni
Why this is correct
This command lists VNIs and their associated VLANs.
- ✗
show vlan id 100
Why it's wrong here
This shows VLAN details but not VXLAN mapping.
- ✗
show interface nve 1
Why it's wrong here
This shows NVE interface details, not VNI-to-VLAN mapping.
- ✗
show running-config vxlan
Why it's wrong here
This shows configuration but not operational mapping.
