Explanation
The ovs-vsctl command (shown as 'ovs-vscl' in the question, likely a typo) is the Open vSwitch control utility used on AHV hosts. Running ovs-vsctl show from the CVM (or AHV host) displays the current bridge and port configuration, including any VLAN tags applied to uplinks or VM ports. This allows an administrator to identify the configured VLAN ID without needing to access Prism. ifconfig shows IP/interface info but not VLAN tags on OVS. manage-ovs is a Nutanix-specific wrapper script useful for some network operations but does not directly display VLAN IDs. acli is the Acropolis CLI for VM/network management but is not the right tool for querying raw OVS VLAN configuration.
