4.2.7Port VLAN

The flow of data on the module is controlled by configuring the Port VLAN settings. The block diagram below illustrates the flow of both the management traffic and the data traffic for a plug-in module (standalone modules do not have backplane access). The data traffic is controlled by a switch matrix which provides complete control of the data traffic. The management traffic is simply enabled or disabled at each port. By default traffic flows between all ports on the module.

Using the Port VLAN settings, data will only be forwarded across the enabled path, unless blocked by one of the other features (Port Access or Tag VLAN). Secure OAM and ah OAM Management data will pass to and from the Management port even if the path has been “disabled”. This allows OAM maintenance functions to always be enabled. Port VLAN control is inactive when Tag VLAN processing is turned on.
