Firepower and Telnet

To my knowledge Firepower does not use Telnet. When creating a session to the sfr module and running a netstat -an I see the sensor listening on port 23

 

 

sfr$ netstat -an

tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN

 

Can anyone tell me why this sensor is listening on tcp port 23 and if this can be turned off?

This seems to be the defaut behavior.

 

Thanks
