Port groups overview

The front-panel QSFP28 100GbE ports on
r2000/r4000 Series
systems support port group functionality. Port groups enable you to change which mode, or port speed, that port uses. QSFP28 ports operate at 100GbE by default, but depending on the optical transceiver module that you have installed in the port, you can configure the port group to use one of these modes:
100GbE mode
Creates one interface at 100G speed. This is the default mode for 100G ports.
​40GbE​ mode
Creates one interface at 40G speed. This is the default mode for 40G ports.
Changing the mode for a port group reboots the system, removes stale interfaces from your configuration, and removes any references to stale interfaces from your configuration. You will then need to reconfigure any previously-configured protocols to use the modified port group.
