Solaris 10: how to enable some cipher or esclude weak cipher on ssh?

On HPUX and Linux servers this line works fine

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128

On solaris10 give me error

/etc/ssh/sshd_config line 155: Bad SSH2 cipher spec 'aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128'

I'm sure ssh on solaris support those ciphers
