Georgia Tech Stitching Confirmation Tests

This pages capture the detailed test logs for each test defined in the New Site Stitching Confirmation Tests page. For the sites status see the New Site Stitching Confirmation Tests Status page.

IG-ST-1 New Site to GPO IG topology

The GATech site advertises the following stitching details:

Experimenter may not need any of this data, but it is helpful to reference when trying to determine how many VLANs are delegated for stitching at the site or how much bandwidth can be requested.
