I have VMs connected to a single NIC port, and that physical port is connected to a physical switch port.
+-------------+ | Server | |+----+ +----+| ||VM_A| |VM_B|| |+--+-+ +-+--+| | +--+--+ | <- Here is a virtual switch (*) +------+------+ | +--+--+ |L2_SW| +-----+
Assuming that the virtual switch (*) in the server can ...
- (downwards traffic) just transport traffic from VMs to the L2 switch being unaware of L2
- (upwards traffic) classify packets to each VMs using its static MAC address table set
are there any ways to configure the physical L2 switch to enable VM_A and VM_B to communicate?
i.e.) I want the L2 switch to send the packets back to the port from which the packet just came
e.g.) Having two static entries in the MAC address tables on the physical L2 switch supports that kind of loopback?
$ mac address-table static <MAC_VM_A> vlan 1 interface <IF0> $ mac address-table static <MAC_VM_B> vlan 1 interface <IF0>
I have CRS326 and CSS326 switches and can consider other switches, too.
