Which command shows the Physical Uplink status for a vmnic?

esxcli network ip get operates at the IP configuration layer (VMkernel interfaces and addresses) and does not report physical link state or uplink status for vmnic devices.

esxcli network nic list queries the physical NIC layer on an ESXi host and outputs per-vmnic details including Name, Link (Up/Down), Speed (Mbps), Duplex, and MAC address. This is the authoritative esxcli command for verifying whether a physical uplink is active and at what speed/duplex it is negotiating. The output maps directly to the vmnic devices visible under the host's physical adapter configuration in the vSphere Client.

esxcli network vmnic list is not a valid esxcli namespace or subcommand - physical NIC status is accessed through the 'nic' namespace, not a 'vmnic' subcommand.

esxcli network ifconfig get is not a valid esxcli command; ifconfig-style syntax belongs to legacy Linux networking tools and is not part of the esxcli command framework used on ESXi.
