3 WCM APPLICATIONS
3.1 WCM Normal Mode
In this application, the WCM is operating with Traffic Isolation Disabled. In this mode, the
WCM acts as a simple, layer 2, 5 port switch with packets switched based on MAC
address alone. The WCM supports both local and remote switching, and forwarding over
the WAN trunk.
Management traffic is not isolated from the through data traffic, and both units may be
managed from any port.
3.2 WCM VLAN Trunk Mode
In this application, WCM-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. WCM-A is
operating with VLAN support enabled but all ports defined as Trunks. A VLAN ID is
allocated to the Manager and thus management traffic is isolated from the user traffic and
the management VLAN, in this case 101, can be used to manage the WCM’s. WCM1100-
B is configured with VLAN support enabled but each port is configured as an access port
and isolated to a single VLAN.
Trunk ports expect packets to be tagged, whilst access ports expect untagged packets and
will add tag and priority to incoming packets.
