In this mode, the WCM1800 acts as a simple, layer 2, 5 port switch with packets being switched based on MAC address alone. -
Page 11: Wcm1800 Vlan Access Mode
11 of 61 METRODATA LTD WCM1400/WCM1800/WCM1820 Quick Start Guide In this application, WCM1800-A is connected to a VLAN enabled LAN switch. The LAN switch is configured as a VLAN trunk and all packets are tagged with VLAN Tags. WCM1800-A is operating with VLAN support disabled, but with a VLAN ID allocated to the Manager. -
Page 12: Point To Multi-Point
12 of 61 METRODATA LTD WCM1400/WCM1800/WCM1820 Quick Start Guide 2.5 Point to Multi-Point In this application, the traffic is transported to remote destinations based on the incoming VLAN C-Tag. To support the point to multipoint management, the IP Proxy mode is used with device A acting as the server and B/C acting as clients. -
Page 13: Theory Of Operation
13 of 61 METRODATA LTD WCM1400/WCM1800/WCM1820 Quick Start Guide 3 Theory of Operation 3.1 Frame Encapsulation The WCM1800 uses the Generic Framing Procedure (GFP) to encapsulate the Ethernet frames for transmission over the WAN link(s). GFP is a byte aligned procedure and hence is suitable for use with multi link bonding. -
Page 14: Virtual Concatenation And Lcas
14 of 61 METRODATA LTD WCM1400/WCM1800/WCM1820 Quick Start Guide The GFP frame contains an optional FCS, Frame Check Sequence. Packets received with an FCS error will be discarded. Since the GFP frame is protected from bit errors by the GFP payload FCS, the MAC FCS may be stripped and recalculated at the remote end to save bandwidth. -
