Description: The hash algorithm used in Phase-1 negotiations on the control tunnel corresponding to this conceptual row.
What is cisgIpsSgTunHashAlgo?
This reports the hash algorithm used in Phase-1 negotiations for this specific control tunnel, per its description - the live per-tunnel record of the integrity algorithm actually protecting this tunnel's ISAKMP message authenticity. As with the encryption algorithm object, it lets an admin verify a tunnel didn't negotiate down to a weaker hash than intended by policy. A tunnel showing 'md5' in an environment that standardized on SHA-256 would be a specific, flaggable weak point in that connection.
