When Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP) is enabled on the distributed switch and the hosts connected to the switch are in Listen or Both operational mode, you can view physical switch information from the vSphere Web Client.
- In the vSphere Web Client, navigate to the host.
- On the Configure tab, expand Networking and click Physical adapters.
- Select a physical adapter from the list to view its detailed information.
According to the enabled switch discovery protocol, the properties of the switch appear under the CDP or LLDP tab. If the information is available in the network, under Peer device capability you can examine the system capabilities of the switch.
