Hi Lucas,
I am not exactly sure on the commands that is needed to enable PBR on switches. However, the commands can be used in AirWave in Config snippet(s) to be pushed to a switch or group of switches. Please make sure prior managing or pushing new config to switch from AirWave, the switches are already with 'Good' config status with Template and (optional depending on config) config snippet option.
There is no option to Telnet/SSH to switches from GUI or CLI menu in AirWave.
