Add SSH configuration options

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.


The ` security ssh add ` command adds additional SSH key exchange algorithms or ciphers or MAC algorithms to the existing configurations of the cluster or a Vserver. The added algorithms or ciphers or MAC algorithms are enabled on the cluster or Vserver. If you change the cluster configuration settings, it is used as the default for all newly created Vservers. The existing SSH key exchange algorithms, ciphers, and MAC algorithms remain unchanged in the configuration. If the SSH key exchange algorithms or ciphers or MAC algorithms are already enabled in the current configuration, the command will does not not fail. Data ONTAP supports the diffie-hellman-group-exchange-sha256 key exchange algorithm for SHA-2. Data ONTAP also supports the diffie-hellman-group-exchange-sha1 , diffie-hellman-group14-sha1 , and diffie-hellman-group1-sha1 SSH key exchange algorithms for SHA-1. The SHA-2 key exchange algorithm is more secure than the SHA-1 key exchange algorithms. Data ONTAP also supports ecdh-sha2-nistp256 , ecdh-sha2-nistp384 , ecdh-sha2-nistp521 , and curve25519-sha256 . Data ONTAP also supports the AES and 3DES symmetric encryptions (also known as ciphers) of the following types: aes256-ctr , aes192-ctr , aes128-ctr , aes256-cbc , aes192-cbc , aes128-cbc , aes128-gcm , aes256-gcm , and 3des-cbc . Data ONTAP supports MAC algorithms of the following types: hmac-sha1 , hmac-sha1-96 , hmac-md5 , hmac-md5-96 , hmac-ripemd160 , umac-64 , umac-64 , umac-128 , hmac-sha2-256 , hmac-sha2-512 , hmac-sha1-etm , hmac-sha1-96-etm , hmac-sha2-256-etm , hmac-sha2-512-etm , hmac-md5-etm , hmac-md5-96-etm , hmac-ripemd160-etm , umac-64-etm , and umac-128-etm .
