+        This module scans network for BigIP HTTP virtual servers based on simple
+        banner grabbing technique. BigIP system uses different HTTP profiles for
+        managing HTTP traffic. In particular, BIG-IP system uses HTTP profile that
+        specifies the string used as the server agent name in traffic generated by LTM.
+        The default value is equal to "BigIP" or "BIG-IP" and depends on BigIP system version.
