Tenho um switch Cisco c2960x de 24 portas, mas neste momento sĆ³ com acesso telnet por via CLI (Putty). Necessito que o switch tenha acesso ssh e gostaria de saber quais os comandos certos para fazer esta configuraĆ§Ć£o, sem estar ligado por consola, mas sim por Putty. Na imagem segue informaƧƵes do switch assim como a seguinte configuraĆ§Ć£o que acho estar relacionada com o modo de telnet:
line con 0
login local
line vty 0 4
login local
transport input all
line vty 5 15
login local
transport input all
Desde jƔ agradeƧo toda a ajuda.

You need
Username xxxx password xxxx
Enable password xxxx
And under vty
Privilege level 15
Also for ssh you need
Ip domain name xxx
crypto key generate rsa

Hello @MHM Cisco World
fyi - Ip domain name xxx not required when you label the crypto key generation

Hello
to enable ssh on the switch you need to do the following:
conf t
crypto key zeroize
crypto key generate rsa label LOCAL general-keys modulus 2048
ip ssh version 2
line vty 0 15
transport preferred none
transport input ssh
transport output ssh
end

Hello paul driver thanks for your help.
Right now after do that sequence comands I not have acess by CLI with ssh or telnet.
The access to the switch maybe only by console

Use
transport input all
transport output all
And you can access via telnet
For ssh
And did you do what I suggest before?

Hello MHM right now I don't have access phisical to switch to do access by console. And can access by CLI. And yes I do your suggest. I'm really newbie in this configurations of switchs, but I'll learn.

Okay leave the cfg I asked yo to implement inplace for the time being.
Are you able to at least reach the switch via ssh or not, if not then you need to give the switch a mgt ip address
int vlan 1
ip address x.x.x.x y.y.y.y.y
not shut
eixt
ip default-gateway x.x.x.x
also I did notice you had login local applied to the vty lines, which indicates you have created a local user account on the switch, have you done that?
Again if not,
conf t
username xxx privilege 15 secret xxxx
exit
Make sure the above is applied and if not perform the above steps and test access once again please.

Friend never run command
transport input ssh
transport output ssh
Before you sure SSH work good
He can not anymore access SW
So he need to access via console
And make
transport input all
transport output all
After that he check ssh' in this case if he failed he can access via telnet

hello
Op confirmed they had console access, hence no reason why not to apply ssh on the vty lines
