+ * @brief Get Channel Authentication Capabilities
+ *
+ * This message exchange provides a way for a remote console to discover what
+ * IPMI version is supported i.e. whether or not the BMC supports the IPMI
+ * v2.0 / RMCP+ packet format. It also provides information that the remote
+ * console can use to determine whether anonymous, “one-key”, or “two-key”
+ * logins are used.This information can guide a remote console in how it
+ * presents queries to users for username and password information. This is a
+ * ‘session-less’ command that the BMC accepts in both IPMI v1.5 and v2.0/RMCP+
+ * packet formats.
+ *
+ * @param[in] inPayload - Request Data for the command
+ * @param[in] handler - Reference to the Message Handler
