Hi everyone,
To all engineers who love cisco CLI, what is the possible solution to this below error
Key exchange failed.
No compatible MAC. The server supports these MACs: hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,hmac-sha2-256,hmac-sha2-512
Any possible solution will be appreciated.
kind Regards,
Michael

Try to add these MAC to the switch:
ip ssh server algorithm mac hmac-sha2-256

Just add this command on the switch(9000 series), if you are having an older version of SecureCRT and it will work .
ip ssh server algorithm mac hmac-sha2-512 hmac-sha1 hmac-sha2-256

Try to run this in the switch
ip ssh server algorith mac hmac-sha2-256
it will add the hash algo in the switch. That works on mine.
