Description: The hash algorithm used in control tunnel negotiations.
What is cisgIpsSgTunHistHashAlgo?
This preserves the hash algorithm used in the negotiations of a now-expired control tunnel, per its description, the historical companion to the live cisgIpsSgTunHashAlgo. It gives an admin the historical integrity-algorithm record for a since-closed connection, useful for the same compliance-audit purposes as the encryption history object. A pattern of history entries all showing MD5 for connections to one specific partner would identify that relationship as a priority for renegotiating stronger hash requirements going forward.
