Connect the cable from the AUX port of the router to the modem, as shown in figure 2. Remember these points: The AUX port on Cisco routers is either RJ-45 or DB-25. If the AUX port is RJ-45, use a flat-satin rolled RJ-45--RJ-45 cable (part number CAB-500RJ= ), which is usually provided with every Cisco router for console connections The AUX line is the Auxiliary port, seen in the configuration as line aux 0. The VTY lines are the Virtual Terminal lines of the router, used solely to control inbound Telnet connections. They are virtual, in the sense that they are a function of software - there is no hardware associated with them. They appear in the configuration as line vty 0 4 Just use a rollover flat cable ( the blue or black flat cable that comes with cisco routers/switches). Use it to connect from aux of one router to console of other router. On the router (aux), configure reverse-telnet configurations so that you can telnet into second router through the aux port. Check this link out Providing you have a Cisco router which is reachable, you can connect a Cisco device's console port to the routers AUX port for remote access by using reverse telnet The method is simple: Step 1. Connect the routers AUX port to console port of the device you wish to connect to with a Straight Through cable. Step 2. Setup the AUX por

A router must have console password so that user can't go to usermode without entering password. If there is no password set on console than hackers can easily access router's usermode and find the information about router. To set a password on console go to the router's configuration mode and run following commands Cisco Routers have a number of different ports through which these routers can be accessed By default any one can access the router and can change configuration In order to limit access and preventing users from changing configurations Cisco allows us to password protect each port In this lab we will set line console password, thus preventing unwanted changes to our configurations Before readi
I should have also noted that I use a console cable that is usb to rj45 and I just connect a patch cable to a port on the cisco device and the Ethernet port on my laptop.

Console Line - The console is the main serial administrative port on a router. This is where you configure the router when it is new and has no network configuration. Aux Line - The aux line is an auxiliary port. Like the console, it is a physical port on every router. You can think of it as a backup console port Before starting any configuration on your network equipment it is essential to protect it with passwords. Every single interface that you have on your router or switch has to be password protected. There are few commands regarding passwords - console, aux, telnet (vty) enable password and enable secret. Here are commands: (config)#enable password test - [ Configuration de base d'un routeur Cisco 1 Mode privilégié Router>en Router# Il faut créer au minimum un mot de passe pour l'accès aux différents terminaux (console et virtuel) et un mot de passe pour l'accès au mode privilégié (enable). 10.5 Création des mots de passe et configuration de la console Router(config)#line con 0. The configuration of AAA authentication methods and policies applied to the mechanism will automatically apply to the console, AUX port, and vty access methods. The AUX port (also called com1), when available, cannot be explicitly disabled Many organizations use Cisco devices to interconnect, protect, filter, and manage networks so it is important to understand ways to improve the security of these devices as part of your informatio
Cisco IOS Packaging for Cisco Routers. How to connect to a Router in order to configure it: You can connect to a Cisco IOS Router either directly or remotely. For the first time when the device is not configured yet, you usually connect directly with a console cable via the CON port or remotely by dialing into a modem connected to the AUX port For more information on cabling, refer to Cabling Guide for RJ−45 Console and AUX Ports and RJ−45 Cables. Routers with DB−25 AUX Ports For routers with a DB−25 AUX port (for example, Cisco 4500, 7200 and 7500) you need a DB−25−to−DB−25 Null Modem cable.

Aux. This is short for auxiliary port. This is also a physical access port on the router. Not all routers have this port. As the aux port is a backup configuration port for the console, it is equally important to configure a password on it. Cell_Router# config t Cell_Router(config)# line aux 0 Cell_Router(config-line)#password Secret!pas How to password protect Console Port. To configure the console password, follow these steps. Router(config)# line console 0 Router(config-line)# password CISCO Router(config-line)# Router(config-line#Ctrl-Z Router# How to password protect Auxilary (AUX Port) Port. To configure the auxilary password, follow these steps Using Telnet for remote management transmits all information, including the username and passwords, in clear text. Using an encrypted password for VTY access ensures that the password cannot be read either in transit or in the configuration file. Passwords used for access to the console, aux, or VTY connections can be encrypted if desired

Follow the below commands to configure Console, VTY and Auxiliary port passwords on a Cisco Switch: Line Console Password. Console port is used to access the switch using a console port. Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#line con Switch(config)#line console Cisco Router Auxiliary Password Setup. To configure the auxiliary password, go into global configuration mode and type line aux ?.You can see here that you only get a choice of 0-0 (that's because there's only one port) Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#line aux ? 0-0> First Line. Follow these steps to configure Auxiliary (AUX) port passwords. Note: before performing this test, ensure that you have an alternate connection into the router, such as console or Telnet, in case there is a problem logging back in to the router. Step 1. From the privileged EXEC (or enable) prompt, enter configuration mode ((config)) and then switch to line configuration mode ((config-line. Similar to the console port, the aux port can be used to gain local access to the router. Typically the aux port is used to provide out-of-band access to the router, such as a modem. If the aux port is not needed, it should be have exec access disabled. The configuration of a Cisco router may include several user/password pairs in the.
Any VPN client can be used to connect to the Router/ Switch if the VPN has been configured on the device. Connection Using Auxiliary port; Every Cisco Router/ Switch in addition to Console Port has an Auxiliary Port, which can be configured to allow non-Network Remote Access t the Router/ Switch When you connect to your router (either via console or vty), you are taken to what is known as User EXEC mode. If you are prompted to enter initial configuration dialog; just type n and hit enter or press Ctrl+Z to skip. Type enable without quotes to enter Privileged EXEC Mode from User EXEC mode. Viewing the Default Configuration All this routing require different command for different protocol, I am still studying on all this cisco command, and soon, will post the easy explanation here when I have better understanding on cisco router routing configuration. To master the cisco router basic configuration, have to do more practice on Packet Tracer, Cisco Simulation Software Console port - Allows you to obtain local administrative access to the router. This port is located behind the router as an 8 pin holder called RJ-45. You can connect the console port to the computer using rollover cable (8 wire cable)
