check below command :
show ip ssh (show you what verion of ssh running)
this should be ssh version 2 as below example :
below commands to make 2048
config t
!
ip ssh dh min size 2048
!
end
check again -show ip ssh

#config t

unfortunatly we can not read someone what they seeing over there.. that is the reason we asked for screenshot here to help.
Cat 2960 Switch has that commands. (what you able to type ?) what prompt are you > or #
Do you have enough rights as admin to go in to config t mode ?
press ? and post the output here to tell you
show priv (tell you what rights you have)

what prompt are you > or # - i am prompted on # which means it is already enabled
#show priv
Current privilege level is 15

you have priv 15, and you enable mode - when you type :
#config t ( what error you get ?)

This looks for me you do not have enough rights to get in to config mode
Reasons :
1. you have priv 15, but restricted commands
2. or centralise radius have restricting the access.
show run (are you able to view config ?) if so post that output here ?

@PaoloArnedo provide a screenshot of the error you receive when you cannot access "conf t" - perhaps you have TACACS enabled and you don't have rights to that command, regardless seeing the error would help.
