Data Plane

This section captures Data plane information for Cornell University detailing site topology, VLAN, Network Providers (I2/Regional) and network address information. Additional site which is not specified, but deemed important, can also be captured here.

Data plane connectivity diagram

Note this is a 1G link, even though it is a te designation. This is because the Pica8 switch that the rack connects to can use either SFP or SFP+ on each of those slots (this on is SFP).

Layer 2 information

Provide layer 2 information for circuits,network connection end-points, and purposes of VLANs.

*In the VLAN column, a single ID indicates that the port is an access port. A T followed by one or more IDs indicates that the port is a trunk (aka tagged) port with those VLAN IDs.
