ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023
ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023 There are three configurations that a network administrator should use for a newly provisioned switch or router.
Although using these configurations ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
may seem like common sense, 90% of the devices I see are missing at least one of these settings, and about 75% are missing two or more.
Use this checklist as an action item to verify that your existing devices have these settings as a minimum and integrate them into any templates or provisioning documents you use ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
You’ll appreciate the consistency it adds to your network management and monitoring results.
I will guide you through the configuration of specific commands that are particularly useful in managing your network and Cisco certification. You can configure the following administrative features on the router and switch:
Remember, none of these options will make your routers or switches work better or faster, but trust me, your life will be much better if you take the time to set up these configurations on each of your network devices ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
That’s because it makes troubleshooting and maintaining your network so much easier – seriously! In this next section, I will demonstrate the commands on a Cisco switch, but understand that these commands are used exactly the same way on a Cisco router ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
Hostnames
We use the hostname command to set the identity of the router. This is only locally significant, meaning it does not affect how the router performs name lookups or how the device actually functions on the network. However, the hostname is still important because it is often used for authentication in many WANs. , Networking Certification in Delhi has become one of the hot topics, people who need a job should really try it ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
Here is an example:
I know it’s pretty tempting to configure the hostname with your own name, but it’s usually much better to name the router something related to its physical location. A name that maps to where the device is located makes it easier to find, which, among other things, confirms that you’re actually configuring the right device.
Although it seems like I’m completely avoiding my own advice by naming my CodecNetwork, I’m not, because this particular device actually lives in the “CodecNetwork” office of CCNA training in Delhi. Its name perfectly maps where it is so it won’t be confused with those on other networks I work with ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023!
Banners
A very good reason to have a banner is to give anyone who dares try to telnet or break into your network a little security warning. And they’re super cool because you can create and customize them to greet anyone who shows up at the router with exactly the information you want them to have!
Here are the three types of banners you need to familiarize yourself with ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
This MOTD banner basically tells anyone connecting to the router to get lost unless they are on the guest list. The part to focus on here is the delimiter that tells the router to handle the message. Obviously, you can use any character for it except the delimiter in the message itself. When you finish the message, press Enter, then the separator character, and then press Enter again. Everything will still work if you don’t follow this routine unless you have more than one banner.
Let’s take a moment to look in more detail at the other two types of banners I mentioned ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
Executive banner
You can configure the line activation (exec) banner to be displayed when EXEC processes such as line activation or incoming connection to a VTY line are created. Simply starting a user exec session through the console port activates the exec banner.
Login banner
You can configure the login banner to display on all connected terminals. It will appear after the MOTD banner but before the login prompt. This login banner cannot be disabled on a per-line basis, so you disable it globally by removing it with the no banner login command.
Note – Remember that the login banner appears before the login prompt and after the MOTD banner ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
Password settings
You will need five passwords to secure your Cisco routers: console, help password, telnet (VTY), enable password, and enable secret. The enable secret key and enable password are used to set the privileged mode security password. After setting the authorization commands, users will be prompted for a password. The other three are used to configure the password when user mode is accessed through the console port, through the auxiliary port, or through Telnet. Let’s take a look at each of them now
The following list describes the password enable parameters ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
password Sets the enable password on legacy systems prior to 10.3 and is never used if the enable secret key is set.
secret A newer encrypted password that will override the enable password if one has been set.
If you try to set the same enable secret and enable passwords, the router will politely prompt you to change the second password. Note that if there are no old legacy routers involved, don’t even bother using an enable password!
And these two lines are especially important for Cisco CCNA training:
console Sets the console user mode password.
vty Sets the Telnet password on the router. If this password is not set, Telnet cannot be used by default. To configure user mode passwords, select the desired line and configure it with the login command so that the switch appears as an authentication prompt.
Let’s focus on configuration
You can still type console line 0 and it will be accepted, but the help screens from this prompt just don’t work. To go back a level, type exit and you’ll find that your help screens are now working. This is a “property”. Really. Since there is only one console port, I can only choose line console 0.
You can set all line passwords to the same password, but it’s not exactly a great security move! And it’s also important to remember to use the login command, otherwise the console port won’t prompt for authentication.
The way Cisco has this process set up means you can’t set a login command before entering a password on a line, because if you set it but don’t set a password, that line won’t be usable ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
You’ll actually be prompted for a password that doesn’t exist, so Cisco’s method isn’t just a problem; it makes sense and it’s a feature after all! Networking training in Delhi helped people to shed light on the basic flaws.
Administrative configuration of a router and switch This post is not about how a router or switch works in a network, but it is still very important. Here we will learn some commands to help you manage your network. The following are the administrative functions you can use to get your work done simply.
None of these options will make your router or switch work faster or better on your network, but believe me, your life will be much better if you take the time to configure them on every network device available on your network.
These are hostnames, banners, passwords and interface descriptions. Since we have already discussed cisco router passwords in depth, there is no need to review them here, instead I will link them to this post so you can find them easily.
Part 1: Router and Switch Administrative Configuration
i. Hostnames
ii. Banners
iii. Descriptions
Part 2: Cisco Router Password in Depth
The above commands make troubleshooting and maintaining cisco ip networks much easier than ever before.
Hostnames
The hostname command is used to set the identity of a router or switch. The hostname can be anything, but it’s better to be descriptive, so I recommend using something related to the location. Assigning a hostname that is somehow relevant to the location of the device will make your administration much easier and also ensure that you are actually configuring the correct device ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
example
Router>
Router>enable
Router#configure terminal
Router(config)#hostname mynetworkinglabs
mynetworkinglabs(config)#
Banners
The banner is used for a small security warning to anyone who dares to try to telnet or dial into your network. In addition, it is used to provide exactly the information you want them to have. Below are the four types of banners that are available in Cisco IOS
Banner Message of the Day (MOTD)
Exec banner creation process
Incoming terminal line banner
Login banner
Message of the Day (MOTD) banner settings
Mynetworkinglabs(config)#banner motd ^ welcome to my networking labs this is the motd banner ^
mynetworkinglabs(config)#
The ^ character marks the beginning and end of a message, you can use any special character instead.
Exec process creation banner settings
Mynetworkinglabs(config)#banner exec # Welcome to my networking labs this is banner exec #Mynetworkinglabs(config)#
This time I used the # character so that you understand that it is not always important to use the ^ character to mark the beginning and end of the message, you can use any special character you want.
Incoming signal banner
Mynetworkinglabs(config)#banner incoming $ this is an incoming banner $Mynetworkinglabs(config)#
Login banner
Mynetworkinglabs(config)#banner login ^ this is the login banner ^
mynetworkinglabs(config)#
Descriptions
You can use a hostname to identify a router or switch, but what about a specific port on the switch or router. The description command is used to identify the port, it is also very useful for administrators. For example, if you come to a router a year after configuring it, you may not remember which port goes to HR and which goes to finance. By adding details with the description command, everyone could know the route of every single port.
example
Mynetworkinglabs(config)#interface FastEthernet 0/0
Mynetworkinglabs(config-if)#description Connected to HR
Mynetworkinglabs(config-if)#exit
mynetworkinglabs (config)
Conclusion
After the above lab configurations, you will be able to provide a security alert, warning, or any other information you want to provide to anyone who tries to log into your device. you will also find that FastEthernet 0/0 is connected to the HR department simply by using the show interface command in privileged mode and that this router’s hostname is Mynetworkinglabs which identifies the router very well.
I just hope that this post can be useful to you and that you could benefit from it. until the upcoming tutorial post, happy routing everyone ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
Many of us will have Cisco-based routers at home or in our organization. And many of us sometimes struggle with the basic steps of router configuration and wrong configuration can be fatal.
Therefore, this post will help you step by step with all the basic Cisco router network configurations to keep your Cisco routers secure and efficient ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
In this post, we will specifically focus on configuring your Cisco routers using the “Command Line Interface” (CLI).
There are certain complex configuration tasks that can easily be done through the CLI, which is why mastering the CLI for your Cisco routers is essential and important. Some of the important CLI configuration/command modes are listed below ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
Mode command
User EXEC mode CiscoRouter>
Privileged EXEC mode CiscoRouter#
Global configuration mode CiscoRouter(config)#
CiscoRouter interface configuration mode(config-if)#
Line configuration mode CiscoRouter(config-line)#
There are also other VLAN-based configuration/command modes such as ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
Mode Config-VLAN CiscoRouter(config-vlan)#
VLAN configuration mode CiscoRouter(vlan)#
A brief overview of all modes with their input and output methods for Cisco router configuration management:
User EXEC mode: This is the first level of access. After accessing the device, you are automatically in user EXEC mode (eg CiscoRouter>). It is used to change terminal settings, perform basic tasks, and list system information.
Privileged EXEC mode: To enter privileged EXEC mode from user EXEC mode, enter the “enable” command.
CiscoRouter> enable
CiscoRouter#
From Privileged EXEC mode, commands used here and in other modes are critical and must be protected from unauthorized users. Privileged access should therefore be password protected. The steps for setting a password to enter Privileged EXEC mode are detailed in the steps below ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
CiscoRouter> enable
Password:
CiscoRouter#
To exit Privileged EXEC Mode to User EXEC Mode, enter the “disable” command.
CiscoRouter# disable
CiscoRouter>
Global Configuration Mode: To enter global configuration mode from Privileged EXEC mode, enter the “configure” command. Global configuration commands apply to features that affect the device as a whole ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
CiscoRouter#configure
CiscoRouter(config)#
To exit global configuration mode to privileged EXEC mode, type “exit” or “end” or press “ctrl+Z”.
CiscoRouter(config)#exit or end
CiscoRouter#
Interface Configuration Mode: To enter interface configuration mode from global configuration mode, specify the interface by typing “interface” followed by the interface identifier.
CiscoRouter#configure
CiscoRouter(config)#interface GigabitEthernet0/1
CiscoRouter(config-if)#
Interface configuration commands modify the behavior of an interface. Interface configuration commands always follow a global configuration command that defines the interface type ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
To exit interface configuration mode to privileged EXEC mode, type “end” or press “ctrl+Z”.
CiscoRouter(config-if)#end
CiscoRouter#
To exit from interface configuration mode to global configuration mode, enter the “exit” command.
CiscoRouter(config-if)#exit
CiscoRouter(config)#
Line Configuration Mode: To enter line configuration mode, you must enter from global configuration mode and enter a line by entering the “line” command.
CiscoRouter(config)# line vty 0 5
CiscoRouter(config-line)#
Line configuration commands modify the operation of the end line. Use these commands to change terminal parameter settings line by line or for a series of lines.
To exit the line configuration mode to the global configuration mode, enter the “exit” command.
CiscoRouter(config line)#exit
CiscoRouter(config)#
To exit line configuration mode to privileged EXEC mode, type “end” or press “ctrl+Z” ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
CiscoRouter(config line)#end
CiscoRouter#
Config-VLAN mode: To enter Config-VLAN mode, you must enter from global configuration mode and enter the “vlan-id” command.
CiscoRouter(config)# vlan 3500
CiscoRouter(config-vlan)#
Use this mode to configure normal-range VLANs (VLAN IDs 1 to 1005) or, if VTP mode is transparent, to configure extended-range VLANs (VLAN IDs 1006 to 4094).
To exit Config-VLAN mode to global configuration mode, enter the “exit” command ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
CiscoRouter(config-vlan)#exit
CiscoRouter(config)#
To exit Config-VLAN mode to Privileged EXEC mode, type “end” or press “ctrl+Z”.
CiscoRouter(config-vlan)#end
CiscoRouter#
VLAN configuration mode: To enter VLAN configuration mode, you must enter from Privileged EXEC mode and enter the “vlan database” command.
CiscoRouter# vlan database
CiscoRouter(vlan)#
Use VLAN configuration commands to create or modify VLAN parameters for VLAN IDs 1 through 1005.
To exit VLAN configuration mode to privileged EXEC mode, enter the “exit” command ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
CiscoRouter(vlan)#exit
CiscoRouter#
How to connect to the router to configure it?
You can connect to the router in two ways
Direct
Distant
For the first time, this means that the device is not yet configured, you can connect directly with a console cable through the CON port. This type of connection is known as an “out-of-band connection”. Once the router is configured accordingly, you can connect remotely using Telnet or SSH. This type of connection is known as an “in-band connection”. SSH is preferred over Telnet because of its encrypted traffic ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
Cisco Router Configuration Step by Step Commands
Step 1: Create local accounts and set a password to access the modes ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023.
The first and most important step in configuring a Cisco router is security. The best way to ensure top security is to add passwords. This way you can secure your access to your Cisco router. You can also add Telnet or Console passwords if needed.
A. To configure a local account with a username and password:
To add a layer of security to your Cisco router, you can create local user accounts with usernames and passwords. This feature works by requiring the username and password set by the user immediately after entering the IP address before entering the CLI. Use the following commands to create local accounts ADMINISTRATIVE CONFIGURATIONS OF ROUTER 2023:
