Hi,

Under the vty lines just add ssh only.

line vty 0 4
 transport input ssh
 transport output ssh

line vty 5 15
 transport input ssh
 transport output ssh

You also need a IOS that support SSH which means you need "K9" in the image name.

we have configured this command 

line vty 0 4
 transport input ssh
 transport output ssh

line vty 5 15
 transport input ssh
 transport output ssh

but still access telnet

BTW, you might get a better response if your open a new question on your issue, rather than posting a reply to an eight year old question.  Also, often helpful to post the exact device and its IOS version (and feature/licenses) being used.

Assuming have console access, what happens if you config as:

line vty 5 15
transport input none
transport output none

Does telnet access still work?
