2.3 VLAN Mode
In this mode, both WCM5100 units have VLAN support enabled. VLAN 101 is used as the
management VLAN and in unit WCM5100-A the VLAN group 101 includes the LAN Port 1,
the Manager and the E1 port. At the remote end, Port 1 is disabled to prevent customer
access to the WCM5100 manager.
2.4 S-Tag Mode
In this mode, the WCM5100 adds a, port based, S-TAG to all incoming traffic. Where
customer traffic is already VLAN tagged, this leads to double tagging or ‘QinQ’ operation.
The use of the S-TAG enables the carrier to isolate customer traffic. Carrier management
traffic is carried with a separate S-Tag giving management access to both units, and on
the customer site the external management access is disabled.
