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 any...
I believe that because Firepower is not HA aware and you have an HA configuration and monitoring Interface dataplane0 you are receiving this error. Do not monitor interface dataplane0 in an HA configuration, the error will disappear.
