Parameters mac mac-list Enter the keyword mac then a space-delimited list of message authentication code (MAC) algorithms supported by the SSH client. The following MAC algorithms are available. When FIPS mode is enabled: ● hmac-sha2-256 ● hmac-sha1 ● hmac-sha1-96 When FIPS mode is disabled: ● hmac-sha2-256 ● hmac-sha1 ● hmac-sha1-96 ● hmac-md5 ● hmac-md5-96 Defaults The default list of MAC algorithm is in the order as shown below: When FIPS mode is enabled: ● hmac-sha2-256 ● hmac-sha1 ● hmac-sha1-96 When FIPS mode is disabled: ● hmac-sha2-256 ● hmac-sha1 ● hmac-sha1-96 ● hmac-md5 ● hmac-md5-96 Command Modes CONFIGURATION Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command Line Reference Guide. Version Description 9.10(0.0) Introduced on the S6100-ON, S6000, S6000-ON, S5000, S4810, S4820T, S3048- ON, S4048-ON, MXL, C9010, S3100 series, and Z9100-ON. Usage Information ● You can select one or more MAC algorithms from the list. ● Client-supported MAC list gets preference over the server-supported MAC list in selecting the MAC algorithm for the SSH session. ● When the MAC (-m) option is used with the SSH CLI, it overrides the configured or default MAC list. ● When FIPS is enabled or disabled, the client MACs get default configuration. ip ssh rekey Configures the time rekey-interval or volume rekey-limit threshold at which to re-generate the SSH key during an SSH session. C9000 Series Syntax ip ssh rekey [time rekey-interval] [volume rekey-limit] To reset to the default, use no ip ssh rekey [time rekey-interval] [volume rekeylimit] command. Security 1569
