9.2.3 Managing virtual switches
For the network connection of a XenVM you configure a virtual Network Interface Card and
assign the connection to a virtual switch. The virtual switch presents the connection to a
network. Depending on the type of network connection required, different types of virtual
switches are needed:
● An internal virtual switch permits a local protected communication link for the XenVMs
attached to it. These switches can also be used by the BS2000 Native system or by
BS2000 VMs for communicating with XenVMs.
● An external virtual switch is assigned to a LAN interface which permits an external LAN
connection. The XenVMs connected to it share this connection for communicating with
external systems.
If more than one unused LAN interface is available, an external vSwitch can also be
assigned to two LAN interfaces. In this case the XenVM connections can be distributed
to the two interfaces (also referred to as “bonds”). This redundant configuration is
designed to ensure the high availability of the LAN connection.
External switches use the LAN interface exclusively.
Displaying configured virtual switches
Ê Select Devices → [<se server>(SE<model>) →] <unit> (SU<x86>) → XenVM devices,
Virtual switches tab.
The Virtual switches tab displays all the virtual switches.
The tab offers the following functionality for managing the virtual switches:
