This port-role assignment in the VPN tagging modes cannot be changed.
Corresponding provisioning options that might be available on the graphical user
interfaces of the management systems do not apply to the VPN tagging modes and are
blocked.
Repeater mode
In the repeater mode, there is no necessity to distinguish between customer-role and
network-role ports, because the repeater mode can only be used in point-to-point
configurations, and there is:
• no tagging mechanism,
• no spanning tree, and
• no GVRP or STVRP.
In the repeater mode, there is simply a LAN port and a WAN port. The LAN port
provides the connection to the end-customer LAN, and the WAN port provides the
connection to the SDH transport network (see “Repeater mode” (p. 8-60)).
