Login to the GENI Monitoring web interface and search for "clemson" in the top left "Search" box in the navigation bar. The search returns all information known to monitoring about the Clemson site(s). In the information returned, you will see that Clemson has 3 aggregates:

As you can see from the details. The clemson-ig rack has 134 nodes, 18 links to remote sites and 278 slivers overall. The other sites have little to no resources allocated, so we will focus on the clemson-ig aggregate. From the initial search, we have have results for:

  • Nodes
  • Switches
  • Links
  • Interfaces
  • VLANs
  • Slivers
  • Checks

From the above list, the VLANs can give us usage statistics. So will focus on VLANs first:
