Can you give me proper command to resolve the issue. please provide the command support 3750V2 switch.
HOST_NAME# show ssh *Mar 1 05:35:37 IST: %SYS-5-CONFIG_I: Configured from console by xyz_usrnm on console Connection Version Mode Encryption Hmac State Username 0 2.0 IN aes256-cbc hmac-sha1 Session started xyz_usrnm 0 2.0 OUT aes256-cbc hmac-sha1 Session started xyz_usrnm %No SSHv1 server connections running.
Given command already I have tried it earlier but it is not taking.

You won't get the option to disable those ciphers on that switch. You can either upgrade to a newer switch or configure access lists to restrict management access to trusted hosts. The 3750 is end of life and i don't think there will be any more software fix for the switch.
