Configure SSH to listen to a range of ports and map them to rotary group.So you need to define the ports manually with the use of the rotary group. Step 3. For SSH access, the tty lines do not listen to the same ports as telnet does. Based on the diagram mentioned, you can say that, for R1 you use line 0/0/0, for R2 line 0/0/1, for R3 line 0/0/8 and for R4 0/0/9. A couple of simple diagrams will help to understand this better.Ī close look at the cables indicates a number in a pattern of P0, P2,….P7 and on the card for the top port the number is from 8 - 15 and the bottom one is from 0 - 7. The numbering schema can be seen on each wire of octal cable as well as on the card. On a HWIC-16A card, two octal cables can be connected. It’s clearly seen from the output that, with the use of a HWIC-16A card, it can give up to 16 tty lines that range from 0/0/0-0/0/15 which allows to connect 16 devices.Įach octal cable has 8 wires. Line(s) not in async mode -or- with no hardware support: Tty Line Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int The number of tty lines can be verified with the use of this command: TS#show line Step 2. Before you configure the terminal tty lines, it’s better to understand how these port mappings work. It’s recommended to use loopback for scalability purpose. Other physical interface IP can also be used for terminal line access. Radius or TACACS authentication method can also be used.Ĭonfigure a loopback interface on the router which can be used later to open reverse telnet/SSH session to vty lines. In the configuration example, local database is used for authentication. Step 1. Ensure that SSH is enabled on the router that you use as terminal server.
#Configure printme terminal Pc
A test PC connects to the terminal sever for console access. Likewise, from octal cable 2, port 0 goes to R3 and port 1 goes to R4. From octal cable 1(0-7) port 0 goes to R1 and port 1 goes to R2. In this diagram, Cisco 2911 has HWIC-16A card is connected to slot 0 and two octal cable connect to total four devices consoles (2 each). If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document is from the devices in a specific lab environment. The information in this document is based on Cisco 2911 router with HWIC-16A module connected.
