Cisco WAE 6.4 Release Notes

New tool to perform capacity planning optimization on plan files.

(Tools > Capacity Planning Optimization)

Enables capacity planning to address increased traffic and congestion.

To alleviate congestion, the optimizer enables:

• Upgrade of existing circuits by adding more capacity to them.
• Augmentation of these circuits with associated port circuits.
• Addition of parallel circuits to existing circuits.
• Specification of new adjacencies between nodes that were not initially connected.

The optimizer operates on both Layer 3 and Layer 1 and provides failure set optimization options.

For more information, see the “Capacity Planning Optimization” chapter in the WAE Design User Guide.

New LSP Setup Bandwidth Optimization tool.

(Tools > LSP Setup BW Optimization)

Creates/removes LSPs for specified LSP groups and shares Setup BW evenly within each group.

For more information, see the “LSP Setup Bandwidth Optimization” chapter in the WAE Design User Guide.

New SR-TE BW optimization tool.

(Tools > SR-TE BW Optimization)

The Segment Routing (SR) TE Bandwidth (BW) Optimization tool enables:

• Reduction of the traffic utilization of selected interfaces to below a specified threshold.
• Analysis on how well congestion mitigation works when using segment routing over different failure scenarios.

For more information, see the “SR-TE Bandwidth Optimization” chapter in the WAE Design User Guide.
