Enable the IOS HTTP web services server and set it to authenticate to a local user database. (GNS3 Only) – Prepare the Routers flash for the SDM installation by formatting Flash:. #CCNA NETWORK VISUALIZER SETUP ROUTER VIA COMMAND LINE PC#
Ensure that you’re able to ping the PC from which you’ll be executing the installation wizard. Configure R1’s hostname and FastEthernet interface with an IP address that is able to communicate to the PC where the installation files are located at. In the next lab you will continue on with installing the Cisco SDM v2.5 manually by copying the required files via TFTP to R1’s disk0. In this lab you will configure the required prerequisites for the Cisco SDM v2.5 installation on flash on R1. If you’re using GNS3 emulated routers then you’ll need to format flash: Since SDM is Java(TM) based application it basically acts as a program that knows all the commands required to configure a Cisco Router and logs into the router via telnet/ssh to configure the router via command line based on the changes you’ve made in the SDM GUI. Prior to installing Cisco SDM there are several lines of configuration required on a Cisco Router such as enabling the Cisco IOS HTTP web server, local authentication and of course the last important required configuration is the VTY line authentication. #CCNA NETWORK VISUALIZER SETUP ROUTER VIA COMMAND LINE FREE#
However, the Free CCNA Workbook does not go into detail in configuring a router using the Cisco SDM, that part is left up to you to explore the possibilities of Configuring a Cisco Router using the Security Device Manager.

This of course has some enraged old school network engineers.Īs of to date September 20th, 2010 the Cisco SDM has been pronounced EoL/EoS (End of Life/End of Service) but if you’re taking the CCNA Exam (640-802) you may still encounter this GUI so with that being said, its best ti familiarize yourself with the SDM until Cisco has officially announced that the SDM is no longer on the CCNA exam.įree CCNA Workbook will teach you how to configure the basic pre-configuration requirements and install the Cisco SDM GUI, after which you’ll be able to access the SDM via web browser. Most engineers are disappointed with Cisco as there are now some types of configurations done via Cisco GUI’s that CANNOT be done using the command line. However, many engineers prefer configuring a Cisco devices via Command Line Interface (CLI). You can enter the vty line configuration mode using the line vty linenumber linenumber command.In the world of Cisco, Graphical User Interfaces are slowly becoming mainstream as Cisco attempts to push their Java based management GUI’s to compete with vendors such as Juniper, Adtran, Lucent, Redback and others.
#CCNA NETWORK VISUALIZER SETUP ROUTER VIA COMMAND LINE PASSWORD#
To configure a password on line vty, you need to use the password and login commands in the line configuration mode.
Telnet or SSH sessions to the device will not be allowed unless a password has been configured and login is enabled. So there can be 5 telnet or SSH sessions to the device at any time. A new telnet or SSH session will use the lowest available vty line. They need not have the same configuration. You can configure all the vty lines together, in a group or one at a time. Each IOS device has a minimum of 5 vty lines (0 to 4). Telnet lines are called vty lines because they are virtual unlike console and auxiliary. The enable password or secret can be configured using the following command in the global configuration mode:Ĭonfiguring the password for the telnet lines is no different, but you need to know two things before doing that: This is called the enable password or secret. The IOS also allows you to configure a password that is required to go to the privileged exec mode. To be able to view or edit the configuration, the user needs to go to the privileged exec mode using the enable command. After reaching the CLI prompt, a user is at the user exec mode where they cannot even view the configuration. The IOS allows you to configure a password on these lines so that anyone connecting to them is required to enter the password before being connected to the CLI. (The term lines is actually reminiscent of very old technologies so do not worry about why they are called such). IOS provides two basic mechanisms for access restriction – line passwords and enable password/secret.Īs you already know, an administrative (exec) session to an IOS device can be started using three methods – console, telnet/ssh and auxiliary. Hence it is essential to secure access to your network devices. A malicious user who gets access to these devices can cause network wide problems such as theft of data, loss of connectivity and more. Routers and switches are the core of your network.
