Console and Auxiliary Port


Console Port

Today, almost all managed networking devices can be done remotely from office. We just need laptop and internet connection than we can work behind the table from the office while drinking a cup of coffee. But, you have to know that before you can do it, you must configure the devices first directly connected. How we could do that? Console port. We can directly connect our laptop to router or switch via console port. From here, we start to configure our network device so that we can manage them remotely.

If we connect to router for the first time, we can access it without login. This makes us easy and of course the router company will not give it password so that we can access them. But, we can not let this happen all day long because it is unsecure, so for the first step we have to do is secure this device. Let’s do it

router>enable
router#configure terminal
router(config)#line console 0
router(config-line)password (your password)
router(config-line)login

Now, try disconnect from the router and reconnect to, the router will ask you password to login.

Auxiliary Port
Actually, I have never worked with this port connection. So far, I just read from internet what the function of the port and this port is used to connect router to modem. To configure auxiliary port, follow the instruction like before, it is similar to console.

router>enable
router#configure terminal
router(config)#line aux 0
router(config-line)#password (your password)
router(config-line)#login

you can do anything to config console and auxiliary, you can check what else you have got by ? At config line prompt

router(config-line)#?

This command is like help command, it will help you to list any command.

Virtual Teletype for Telnet and SSH

Talk about devices configuration (router, switch, hub, server), for the first time, all of them have to be configured directly via console before it can be reconfigured or managed remotely via Telnet or SSH. In order to manage device remotely, first, we have to create gate at the device. In this case, we have something named vty or virtual teletype. Actually, This gate has axis in the router or switch but if we don’t set the password of them we will be rejected automatically by the device when we try to access to them via Telnet or SSH. “ Virtual teletype ( VTY ) is a command line interface (CLI) created in a router and used to facilitate a connection to the daemon via Telnet, a network protocol used in local area networks.” (techopedia.com) Let’s get started to configure the vty. It is very simple actually, just enter to global configuration and then execute line vty than set the password. router>enable router#configure terminal router(config)#line vty 0 5 rou...

Local Login Security Global security

In this tutorial, I would like to introduce you to global security configuration. This is the configuration that can be used to all over security access like vty, console, and auxiliary. First, let’s set the securtiy than we implement to the line accesses. Router#configuration terminal Router(config)#username cisco password cisco Router(config)#username cisco privilege 2 That’s all. Now, You can use this security configuration as global configuration for vty (telnet or ssh), auxiliary, and console. Enter the line configuration and use login local as login security. router#configuration terminal router(config)#line vty 0 5 router(config-line)#login local the procedure is same for auxiliary and console, you just enter to the line than set login to login local router#configuration terminal router(config)#line console 0 router(config-line)#login local router#configuration terminal router(config)#line aux 0 router(config-line)login local Now,...
