To configure bandwidth management for a VPLS
Note: In order to configure required bandwidth, you must enable the Multi-Segment Tunnel Selection and Service Bandwidth Management checkboxes on the Services tab on the NFM-P System Preferences form. For more information, see the procedure to configure NFM-P system preferences in the NSP System Administrator Guide.
Steps
1 |
Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens. |
2 |
Choose a VPLS and click Properties. The VPLS Service (Edit) form opens. |
3 |
Click on the Bandwidth button. |
4 |
Click on the Required Bandwidth tab to configure service tunnel required bandwidth for the service. |
5 |
Configure the Bandwidth Method parameter. |
6 |
If you set the Bandwidth Method parameter to Input Manually or Calculate From SAPs, configure LSP Path Booking parameter. |
7 |
If you the Bandwidth Method parameter to Input Manually, enter a required bandwidth value for each CoS (see CoS 0 Bandwidth - CoS 7 Bandwidth). |
8 |
Click on the Bandwidth Reserved Tunnel tab to reserve PBB tunnel bandwidths. |
9 |
For each CoS, enter a value for the CoS Reserved Bandwidth (Mbps) to specify how much bandwidth this tunnel will reserve in the network. |
10 |
Click on the Reserve Bandwidth button. This action checks to ensure that all the active links in the B-VPLS have enough bandwidth to admit the tunnel into the network and book the bandwidth. The tunnel status will be updated appropriately, based on the outcome of the action. Once the bandwidth is reserved, the BW Utilization tab on the applicable Physical Link properties form will also show this tunnel and the bandwidth information. Note: The reserved bandwidth of the tunnel can be changed at any time after the service creation. However, if a change to the reserved bandwidth causes the used bandwidth to be greater than the requested change, or if there is insufficient bandwidth in the network to facilitate this change, then it will be denied and an appropriate message is displayed. Once bandwidth is reserved on the tunnel, any changes to the topology of the B-VPLS (for example, uplinks added, STP state changes, and so forth) will be updated automatically with the correct bandwidth information on the underlying physical links. If there is insufficient bandwidth available when the changes happen, the bandwidth will still be booked on the physical links and the appropriate alarms will be raised. To unreserve bandwidth of the tunnel after the service creation, you can set all of the configured Cos Reserved Bandwidth parameters back to 0. However, this can only be done when there are no longer any i-services riding on this PBB Tunnel. After the service has been created, the Tunnel Usage tab shows all the i-services currently using this tunnel and the specific bandwidth usage per service. |
