3.1 Switch Ports Overview
3.1.1 Interface Links
In addition to two SFP+ interfaces, there is also an ethernet switch on the XG-7100. There are eight ethernet ports on
this switch that are physically accessible - these interfaces are referred to as ETH1-ETH8. In addition to those 8 ports,
there are also three additional ports that operate behind the scenes - PORT 0, PORT 9 (ix2), and PORT 10 (ix3).
ETH1-ETH8 are gigabit switchports.
PORT 9-10 are 2.5 Gbps uplink switchports. These two ports connect the ethernet switch to a Denverton SoC. The
SFP+ interfaces (ix0 and ix1) also connect to this SoC.
The diagram below demonstrates how these interfaces are connected:
