enable ssh on switch but keep telnet until i can log in ssh

[robertkwild]

hi all,

i want to enable ssh on some switches but still keep telnet until i can login ssh and then i will disable telnet, is this a good how to to follow

https://networkproguide.com/how-to-enable-ssh-on-cisco-catalyst-switch-router/

but when it comes to step 9 i imagine i do this

transport input ssh telnet

and then i can log in ssh and if all good i can chage it back to

transport input ssh

is that correct?

[robertkwild]

when i do

crypto key generate rsa

is there a way to specify you want it 2048 on the same command?

[robertkwild]

ok ive changed to 2048 with one command but its not setting it

crypto key generate rsa modulus 2048
% You already have RSA keys defined named hostname.domain.com
% They will be replaced.

% The key modulus size is 2048 bits
% Generating 2048 bit RSA keys, keys will be non-exportable...
[OK] (elapsed time was 8 seconds)

do show ip ssh | i size
Minimum expected Diffie Hellman key size : 1024 bits
