Recently done a port scan on CSS.


Any idea how I can closed of the listening ports TCP 1720, 1863 and 3128?


Are these ports used by CSS for internal comms?


Please advise

  • Cisco Employee,

We do not listen to those ports.

[[email protected] cisco]# telnet 192.168.20.120 1720

Trying 192.168.20.120...

telnet: connect to address 192.168.20.120: Connection refused



Do you have a 0.0.0.0/0:1720 content rule ?

Do a 'sho rule-summary' to check.
