Virtual Switches
By providing layer-2 connectivity, a Virtual Switch connects Virtual Systems and facilitates sharing a common physical interface without segmenting the existing IP network. As with a physical switch, each Virtual Switch
Virtual Device on a VSX Gateway or VSX Cluster Member that functions as a physical switch. Acronym: VSW. maintains a forwarding table with a list of MAC addresses and their associated ports.
In contrast to a Virtual Router Virtual Device on a VSX Gateway or VSX Cluster Member that functions as a physical router. Acronym: VR., when sharing a physical interface via a Virtual Switch there is no need:
-
To allocate an additional subnet for IP addresses of Virtual Systems connected to the switch.
-
To manually configure the routing on the routers adjacent to the shared interface.
You can create multiple Virtual Switches in a virtual network topology.

Note - When sharing a physical interface via a Virtual Switch, the IP addresses for Virtual Systems connected to a Virtual Switch should be allocated from the same subnet as the shared interface. |
