  1. Reverse Telnet Console(DTE) or Aux RS232- RJ45 Adaptor Line 1 Async Port (DTE) Loopback1 172.21.1.1 telnet 172.21.1.1 2001 • PC에서 C2501-1 등의 라우터에 연결한다. • #telent 172.21.1.1 2001을 사용한다. • #telnet 172.21.1.1 후, #show host, #host1, ctrl+shift+6+x, #show session, #resume 1

  2. Terminal Server Configuration ip host host1 172.21.1.1 ip host host2 2002 172.21.1.1 ip host host3 2003 172.21.1.1 interface Loopback1 ip address 172.21.1.1 255.0.0.0 line 1 16 session-timeout 20 exec-timeout 0 0 transport input all (or, transport input telnet) auto hangup (Clear line을 해도 안끊어 지는 경우에 사용한다.) int s 0/1 physical-layer async (Interface가 Sync/Async 겸용인 경우에 사용한다.) int s 0/2 physical-layer async int s 0/3 physical-layer async • Sync/async interface를 asynchronous mode로 사용하기 위해서는 physical-layer async명령을 사용한다.

  3. Line Number • Console Port(CTY)가 0번이 된다. • Async Port(TTY)가 1번에서 포트 수 만큼의 Number를 점유한다. • Aux Port(AUX)는 Async Port 다음 Number를 점유한다. • Telnet Port(VTY)는 Aux Port 다음 번호를 점유한다.
