    16541654=== Bandwidth and VLAN Negotiation ===
    16551655
    1656 The stitcher tool does not directly negotiate bandwidth. Bandewidth can be requested in the property on a link and possibly some aggregates along the network path may refuse your request if you can't get it and allocate some other amount.
    1657 
    1658 VLAN Negotiation is accomplished by the stitcher.py trying to request a VLAN in the available range, and if requested VLAN is not available, then the next VLAN in the range is tried.  This is repeated until a requested VLAN is available.
