The set ssl_tls_ciphers command allows you to enable or disable the SSL/TLS cipher suites. You can enable any specific cipher suite or all the cipher suites. The default cipher suites are enabled in a specific order. However, you can change this default order. Note that you cannot disable all the cipher suites. At least one cipher suite must be enabled.
The default cipher suites are enabled in the following order:

  1. TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
  2. TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
  3. TLS_DHE_RSA_WITH_AES_128_CBC_SHA
  4. TLS_DHE_RSA_WITH_AES_256_CBC_SHA
  5. TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
  6. TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
  7. TLS_RSA_WITH_AES_128_GCM_SHA256
  8. TLS_RSA_WITH_AES_128_CBC_SHA
  9. TLS_RSA_WITH_AES_128_CBC_SHA256
  10. TLS_RSA_WITH_3DES_EDE_CBC_SHA
  11. TLS_RSA_WITH_AES_256_GCM_SHA384
  12. TLS_RSA_WITH_AES_256_CBC_SHA
  13. TLS_RSA_WITH_AES_256_CBC_SHA256

You can also enable the following cipher suites that are disabled by default:

  • TLS_DHE_DSS_WITH_AES_256_CBC_SHA
  • TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA
  • TLS_DH_DSS_WITH_3DES_EDE_CBC_SHA
  • TLS_DHE_DSS_WITH_AES_128_CBC_SHA
  • TLS_RSA_WITH_RC4_128_SHA
  • TLS_DHE_DSS_WITH_AES_256_GCM_SHA384
  • TLS_DHE_DSS_WITH_AES_256_CBC_SHA256
  • TLS_DHE_DSS_WITH_AES_128_GCM_SHA256
  • TLS_DHE_DSS_WITH_AES_128_CBC_SHA256

You can use the show ssl_tls_ciphers command to view the enabled SSL/TLS cipher suites. For information, see show ssl_tls_ciphers.

Syntax
