Configuring the SSH Server Cipher List
To configure the cipher list supported by the SSH server, use the ip ssh server cipher 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
• aes192-ctr
• aes256-ctr
The default cipher list is aes256-ctr, aes256-cbc, aes192-ctr, aes192-cbc, aes128-ctr, aes128-cbc, 3des-cbc.
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 SSH Client Cipher List
To configure the cipher list supported by the SSH client, use the ip ssh cipher cipher-list command in CONFIGURATION mode.
cipher-list-: Enter a space-delimited list of ciphers the SSH Client supports.
The following ciphers are available.
• 3des-cbc
• aes128-cbc
• aes192-cbc
• aes256-cbc
•
aes128-ctr
• aes192-ctr
• aes256-ctr
The default cipher list is in the given order: aes256-ctr, aes256-cbc, aes192-ctr, aes192-cbc, aes128-ctr, aes128-cbc, 3des-cbc.
Example of Configuring a Cipher List
The following example shows you how to configure a cipher list.
Dell(conf)#ip ssh cipher aes128-ctr aes128-cbc 3des-cbc
