The implementation of Provider Bridge is a network of up to seven virtual bridges
connected in a “cross-like” fashion. Each component acts as a virtual bridge. A
component can have both external and internal ports. An external port name is identical
to its interface name. An internal port name uses the name of its peer component.
Bridge component types:
S Component – an S component handles traffic tagged with S-VLANs.
A single S component (named S1) is the heart of the bridge and cannot be deleted. All
packets passing through this bridge must be tagged with S-VLAN.
C Component – a C component handles traffic tagged with C-VLANs.
On EH-1200F/FX and EH-600T systems: By default, no C components defined (“Single
Component Bridge Model”). Up to 6 C components (named C1 to C6) can be defined.
On EH-1200/TL systems: By default, C components defined (“Single Component Bridge
Model”). Up to 4 components (named C1 to C4) can be defined.
All packets passing through this bridge must be tagged with S-VLAN.
You can change the default bridge configuration to suit your network by removing or
adding the desired bridge components.
