z/VM Networking Properties window

Use the z/VM Networking Properties window to view all the networking entities (guest LANs, VSWITCHes or OSAs) that exist on the z/VM. These entities can be used for networking of the Linux guest systems.

This window provides a list of all the networking connections on the z/VM, and their details, in a read-only table. You cannot edit these fields in the table but you can double-click a line in the table to open the Connection Properties window for that connection.
