修改内容: 我正在学习管理信息库mib,在管理信息结构的定义时,用到以下语句,如 tcMaxConn OBJECT-TYPE SYNTAX INTEGER ACCESS read-only STATUS mandatory DESCRIPTION "The linit on the total number of TCP connection the entity can support" ::=(tcp4) 又如管理对象的宏定义: OBJECT-TYPE MACRO::= BEGIN TYPE NOTATION::="SYNTAX"type(TYPE ObjectSyntax) "ACCESS" Access "STATUS" Status DescrPart ReferPart IndexPart DefValPart VALLUE NOTATION::=value(VALLUE ObjectName) Access::="read-only/read-write/write-only/not-accessible Status::=mandatory/optional/obsolete/deprecated DescrPart::="DISCRIPTION" value(description DisplayString)/empty ReferPart::="REFERENCE" value(reference DisplayString)/empty IndexPart::="INDEX"(IndexTypes) DefValPart::="DEFVAL""("value(defvalue ObjectSyntax)")"/empty DisplayString::=OCTET STRING SIZE(0..255) END 请问这是什么语言?各语句的具体格式是怎样的?
