• hmac-sha2-256
The default HMAC algorithms are the following:
• hmac-sha2-256
• hmac-sha1
• hmac-sha1-96
• hmac-md5
• hmac-md5-96
When FIPS is enabled, the default HMAC algorithm is hmac-sha2-256,hmac-sha1,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 HMAC Algorithm for the SSH Client
To configure the HMAC algorithm for the SSH client, use the ip ssh 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-md5
• hmac-md5-96
• hmac-sha1
• hmac-sha1-96
• hmac-sha2-256
The default list of HMAC algorithm is in the following order:
• hmac-sha2-256
• hmac-sha1
• hmac-sha1-96
• hmac-md5
• hmac-md5-96
When FIPS is enabled, the default HMAC algorithm is hmac-sha2-256, hmac-sha1, hmac-sha1-96.
