Lets list logical switches and verify the Logical switches information from nsxcli command line on ESXi, KVM, NSX Edges and NSX Controller nodes. In order to get the logical switches information from the nsxcli command line run the “get logical-switches” command on the Transport nodes (ESXi, KVM and NSX Edge noes) and Controller nodes. In the previous blog posts, we have seen how to create the logical switches and how to connect vSphere and KVM virtual machines to logical switches.
To get the logical-switches information from the nsxcli command line on the ESXi/KVM hypervisors,
- Log in to the hypervisor hosts (ESXi/KVM) with the root credentials
- Type nsxcli command to enter into the nsxcli command-line prompt.
To list logical-switches information on the ESXi host:
The following are list of possible command line options to get logical-switches information, that includes the number of logical-switches available on the ESXi host, arp-table, mac-table and vtep-table for a given logical switches. If you arent sure of the command options, you may type the partial command and then press the TAB key to list all the possible options available for a specific command.
esx-04a.corp.local> get logical-switch
% Ambiguous command: get logical-switch
Possible alternatives:
get logical-switch <logical-switch-id>
get logical-switch <logical-switch-id> arp-table
get logical-switch <logical-switch-id> mac-table
get logical-switch <logical-switch-id> vtep-table
get logical-switch {local | remote} {mac-cache | arp-cache | vtep-cache} <vni>
get logical-switch-port status get logical-switches
List logical switches on ESXi host:
To list all the logical switches available on the ESXi host, run the get logical-swiches command.
This command will show the following details in the command output.
- Host switches configured on the ESXi host under Overlay Kernel Entry sectionwith the VNI, DVS Name and VIF num
- Logical switches information under the Overlay LCP Entry section with the logical Switch VNI and Logical Switch UUID
- VLAN backed logical switches under the VLAN Backed Entry Section with the Logical Switch UUID and VLAN ID.

List Logical Switches details:
If you want to get more details for a specific VNI, run the following command. The command output includes the details of the DVS Name, VNI, Replication mode configured for a given logical switch, Multicast proxy, Controller IP details, etc.,
