Conguring the SSH Client Cipher List
To congure 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.
