Hello,

 

'DC' is direct connect, a file sharing protocol. TCP port 2001 is also often used for reverse telnet connections. If you don't need it, you can block it with an access list:

 

Router(config)# access-list 101 deny tcp any any range 2001 2999
Router(config)# access-list 101 permit ip any any
!
Router(config)# interface GigabitEthernet 0/1
Router(config-if)# ip access-group 101 in
