Virtual switch operation modes
The virtual mode can be set to:
• Point to point LAN. In this mode the Ethernet interfaces are connected in a
point-to-point manner across the SDH network. The Virtual switch supports 1 LAN
port and 1 WAN port. The principle of the TransLAN is described in “Concepts”
(p. 9-3).
• LAN-Interconnect. In this mode a LAN group contains multiple LAN ports and
multiple WAN ports. Only one end user is connected to one or up to four LAN
port(s). The NE functions as a learning bridge; Spanning Tree algorithms are
supported. The principle of the TransLAN+ type is described in “Concepts” (p. 9-3)
.
• LAN VPN (Virtual Private Network), also mentioned as M-LAN. In this mode a
LAN group contains multiple LAN ports and multiple WAN ports. The LAN
port(s) can be shared by multiple end users. The NE functions as a learning bridge;
Spanning Tree algorithms are supported. The principle of the M-LAN type is
described in “Concepts” (p. 9-3).
WAN port capacity
On the 1643 AM or 1643 AMS network element, there are 4 WAN ports totally in a
LAN unit. The mode of the WAN ports 1~4 is given in the table below. Each mode
stands for a type of the capacity combination of the WAN ports. Any other
combination is not allowable currently. Each of the factors Xa, Xb, Xc, and Xd can be
range from 1 to 5 respectively.
