Interoperability of operational modes
Virtual Switches that are configured in the same operational mode can interwork.
Virtual Switches not configured in the same operational mode do not interwork in all
cases. If a Virtual Switch is configured in the "Repeater" mode or the "STP Switch"
mode, it can only interwork with Virtual Switches that are configured in the same
mode.
Interworking between a remote LAN-interconnect virtual switch and a VPN virtual
switch is not prohibited, because the LAN-interconnect mode can be seen as a special
case of the VPN mode.
Repeater mode
A virtual switch in repeater mode consists of exactly one LAN port and one WAN port
in a fix 1:1 relationship. All Ethernet frames entering the virtual switch at a LAN port
are transparently forwarded to the corresponding WAN port and transported over the
network. None of the standard IEEE Std 802.1D/Q processes (MAC address learning,
MAC frames forwarding and filtering, VLAN classification and filtering) applies.
Received frames are relayed to the other port of the virtual switch, irrespective of their
format or contents.
