Traffic provisioning
be provisioned with this VLAN ID. In automatic mode, the GVRP protocol will take
care of the dynamic VLAN ID provisioning. The user has the possibility to flush
dynamic VLAN's, thus remove dynamic VLAN's that are no longer used.
Only independent VLAN learning is supported. This means, if a given MAC address is
learned in a VLAN, the learned information is used in forwarding decisions taken for
that address only relative to that VLAN.
For the IEEE 802.1Q VLAN tagging mode, the oversubscription mode is not supported
(cf. "Quality of Service (QoS) overview" (p.
Configurable spanning tree parameters
Even though the management system is an SDH network element manager, the data
networking problems still need to be addressed when managing network elements
carrying Ethernet traffic. As such the following parameters are visible/provisionable per
virtual switch.
• bridge address
• bridge priority
• root cost
• root port
• port priority
• bridge priority
Provider bridge mode
The provider bridge mode, a double tagging mode with provisionable TPID
("Ethertype"), is - from a functional point of view - comparable to the LAN-VPN with
the chief difference that the provider bridge mode is compliant to the IEEE 802.1ad
standard while the VPN modes are Alcatel-Lucent proprietary modes, and that the
provider bridge mode supports Quality of Service features while the LAN-VPN does
not.
Traffic is forwarded based on the destination MAC address and the outer VLAN tag
(S-tag).
As in the IEEE 802.1Q STP virtual switch mode, a virtual switch in the provider
bridge mode is a set of LAN/WAN ports on a physical switch that are used by
different VLANs which can share the common WAN bandwidth. VLANs in the same
virtual switch are defined by their VLAN port member set. An instance of the spanning
tree protocol runs on the WAN ports for each virtual switch.
The LAN ports and WAN ports can be configured to be customer-role or network-role
ports (see
In the provider bridge mode, the IEEE 802.1ad VLAN tagging mode is used (see
