Provisioning a virtual switch in spanning tree mode
...................................................................................................................................................................................................................................
When to use
To route Ethernet packets from different customers which are using the same physical
LAN port to more than one WAN port.
The Provisioning a virtual switch in spanning tree mode procedure is also applicable to
X5IP.

• “Parameters for provisioning a LAN unit in repeater mode” (p. 8-114)
• “Ethernet over SDH” (p. 8-24).
Before you begin
Before provisioning a virtual switch determine and check the following:
• the tagging mode of the LAN unit is set to IEEE802. 1Q / IEEE 802.1ad
• the virtual switch name and label
• the LAN port name, label and members
• the WAN port label and members
• the LAN and WAN port details information
• the Rate Control of the Virtual Switch (QoS Oversubscription enable or disable)
• for QoS provisioning of the LAN port, the traffic class assignment, the operation
mode (strict policy or over subscription, the CIR, the scheduler method and weight.
• for QoS provisioning of the WAN port, the traffic class assignment, the scheduler
method and weight.
• deleting a virtual switch will detach all the associated LAN ports or WAN ports. If
these ports carry traffic, this traffic will be lost
• the Traffic Class Assignment and LAN and WAN port number
• for QoS provisioning of the LAN port, the Traffic Class Assignment, the
Forwarding Class and CIR
• for QoS provisioning of the WAN port, the type of policy for the selected queue
and weight.
• detaching a LAN port or a WAN port can disrupt traffic over these ports
For provisioning a virtual switch in the Spanning Tree mode the following must be
performed:
• create a virtual switch
• provision LAN and WAN port details
• provision the TUG structure and create cross connections between the WAN ports
