2.34 Edge virtual switch function

Edge virtual switch (Edge Virtual Bridging) function is a necessary for the adjacent switch connected to the
server in the server virtualization environment. A virtual switch which operates on server virtualization software
exists in the server visualization environment, and the communication is switched between virtual machines.
Therefore, process according to the form of a virtual switch is necessary in the adjacent switch. The following
elemental technologies are supported as an edge virtual switch function in this device.
▪Virtual Ethernet Bridge (VEB)
The communication between virtual machines on the same physical machine is carried out with virtual switch
which operates in the virtualization software.
▪ Virtual Ethernet Port Aggregator (VEPA)
It is a technology which off loads the process of a virtual switch to external physical switch. A physical switch
identifies an individual virtual machine by the MAC address, and the frame of virtual machine address on the
same physical server is transmitted by reflective relay.
Points to be noted
▪ When STP (spanning tree) function is defined, that port cannot be used.
▪ When the function is to be defined in linkaggregation, define similarly in all the ports that constitute the
linkaggregation.
