● aes192-ctr
● aes256-ctr
The default cipher list is 3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr
Example of Configuring a Cipher List
The following example shows you how to configure a cipher list.
Dell(conf)#ip ssh server cipher 3des-cbc aes128-cbc aes128-ctr
Configuring the HMAC Algorithm for the SSH Server
To configure the HMAC algorithm for the SSH server, use the ip ssh server mac hmac-algorithm command in
CONFIGURATION mode.
hmac-algorithm: Enter a space-delimited list of keyed-hash message authentication code (HMAC) algorithms supported by the
SSH server.
The following HMAC algorithms are available:
● hmac-sha1
● hmac-sha1-96
● hmac-sha2-256
● hmac-sha2-256-96
The default HMAC algorithms are the following:
● hmac-md5
● hmac-md5-96
● hmac-sha1
● hmac-sha1-96
● hmac-sha2-256
● hmac-sha2-256-96
When FIPS is enabled, the default HMAC algorithm is hmac-sha1-96.
Example of Configuring a HMAC Algorithm
The following example shows you how to configure a HMAC algorithm list.
Dell(conf)# ip ssh server mac hmac-sha1-96
Configuring the SSH Server Cipher List
To configure the cipher list supported by the SSH server, use the ip ssh server ciphers cipher-list command in
CONFIGURATION mode.
cipher-list-: Enter a space-delimited list of ciphers the SSH server will support.
The following ciphers are available.
● 3des-cbc
● aes128-cbc
● aes192-cbc
● aes256-cbc
● aes128-ctr
