Remotely connect to console ports

I would like to console into any of my 30 cisco devices from anywhere on my network. Anyone have a suggested device to terminate all the console connections? It would be a device that can be placed on the network with an IP and then connect to that device and choose which device to console to. Any advice would be greatly appreciated. Thanks!

Re: Remotely connect to console ports

Conecting to the console port would require a multiplex arrangement. However, you can telnet into both levels of programming any cisco routers by telnet xxx.xxx.xxx.xxx the ip address of the router

Does that help or do you really want "console' connections.

Re: Remotely connect to console ports

Hi,

you can a use a terminal server to connect the console of routers and all other serial console like UNIX box. I use a Digital DECServer. Have a look at http://www.dnpg.com/products-decserver.htm.

Re: Remotely connect to console ports

Hi,

I saw ur Email about the DEC Terminal Servers, we use them also to connect to Servers ( Unix, Alpha, Linux ) via Serial Interface. Is there anyway to integrate Security , so that when somebody logs in to a server in this way ( telnet PortNr) that he should provide username & Password. we configure the Terminal Server Ports as Printer Ports and connect them to Servers Serial interfaces.

Another question do u know where can i get Support for DecTerminal Servers ( Software).

Thanks

apritiate it very much if u could help.

Re: Remotely connect to console ports

You can use nearly every CISCO router that can be equipped with a multi serial interface card. E.g. a 2600 or 3600 series router with a NM-16A or NM-32A module inside.

Re: Remotely connect to console ports

I like the idea of using a 2600 or 3600. SInce we already own many of those. What type of cable would then connect from the NM-32a to the console port? My next question is: assuming I had one connected like you suggest, how then do you connect to the console port? Through a CLI from the 2600?

Re: Remotely connect to console ports

Hi

can use Cisco Terminal Servers

A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other serial devices, such as modems or console ports on routers or switches.

See

Re: Remotely connect to console ports

You can use a cable like that:

CAB-OCTAL-ASYNC

You can connect these cables to your patch field and make the connection from there to the console ports of your routers. But you should verify that this cable is the right one.

Example:

You have plugged the NM-32a into slot 2 of your 3600. This result into port base number 2000 ("2" from the slot number). To reach the right console you have to add the line number. The resulting port has to be used in connection with any ip address of your 3600:

Module in slot2; ip address of 3600 is 1.2.3.4; selected console port 64:

telnet 1.2.3.4 2064

You will get a prompt for the username and the password for this line and after pressing you are connected with the console of the device.

Configure something like that:

line 64

password

login authentication LINE

terminal-type vt100

no exec

transport input telnet

transport output telnet

You have to do this for every single device or you can summarize the configuration for your devices with

something like that:

line 64 95

....

The line numbers and the port number base depend on your hardware and the slot number. Just type "show diag" and "show line" after you have equipped your router with the module and you see what kind of ttys are available.

You might want to check into a Cyclades Terminal Server. www.cyclades.com
