Which Connection Provides A Secure Cli Session With Encryption To A Cisco Switch?

An SSH connection provides the secure CLI session with encryption to the cisco switch. Today let us discuss bout the SSH connection in detail.

Now, let us configure the SSH session for the cisco switch or the route. We apply the same process for any kind of switch or router. Here, have five steps, let us discuss each step in detail.

Firstly, we need the hostname, domain name, and the creation of the SSH key or the generate key, creating of the user and we enable the switch.

Now open the command prompt and type enable and press enter and type conf t, now we can see that it displays as, enter the configuration commands. Now, we type the hostname coplex and we press enter.

Now we are going to the domain name, we type Ip domain-name coplex.co.uk and then press the enter button.

Now we are going to generate the key by simply using the crypto command like crypto key enter crypto key ge enter, and then crypto key generate RSA and then press enter.

Now, if already RSA keys are present it displays as already RSA keys are present and ask if we want to replace them. Then type Y and then press enter.

Now it asks how many bytes are present, so the bigger number that we give the stronger the key will be, and then the key will be generated after a few minutes.

After this, we try to enable the ssh session, now we type the line VTY 0 15. Here this has the channels of which remote we want to change it and then we simply press the enter button and type transport input Ssh and then press enter.

Here it will configure the switch and if we want to add andy additional user, we first simply exit from it and type create user name password and password name that we want to give.

And if we want to enable the local login, we again need to type the line VTY 0 15 and then press enter and type login local enter exit from it.

Now, after this, let’s test how does it work. Now if you have putty open the putty and give the IP address and open it. Now we can see the login command. since we haven’t set up any IP address, we give the user name and its password and this is the process of setting up the SSh session.

And if we want to set the IP address on the VLAN, we simply type the config enter and type configure t and type interface VLAN 1 enter and type the IP address and type the IP address we want to give and then press enter.

Here the Ip address should be of the same network as the computer until unless we use the nat, we use the same IP range, and hence this is how to set up the ssh session.
