SnmpTLSAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1a"
    STATUS       current
    DESCRIPTION
        "Represents an IPv4 address, an IPv6 address, or a
         US-ASCII-encoded hostname and port number.

An IPv4 address must be in dotted decimal format followed by a
        colon ':' (US-ASCII character 0x3A) and a decimal port number
        in US-ASCII.

An IPv6 address must be a colon-separated format (as described
        in RFC 5952), surrounded by square brackets ('[', US-ASCII
        character 0x5B, and ']', US-ASCII character 0x5D), followed by
        a colon ':' (US-ASCII character 0x3A) and a decimal port number
        in US-ASCII.

A hostname is always in US-ASCII (as per RFC 1123);
        internationalized hostnames are encoded as A-labels as specified
        in  RFC 5890.  The hostname is followed by a
        colon ':' (US-ASCII character 0x3A) and a decimal port number
        in US-ASCII.  The name SHOULD be fully qualified whenever
        possible.

Values of this textual convention may not be directly usable
        as transport-layer addressing information, and may require
        run-time resolution.  As such, applications that write them
        must be prepared for handling errors if such values are not
        supported, or cannot be resolved (if resolution occurs at the
        time of the management operation).

The DESCRIPTION clause of TransportAddress objects that may
        have SnmpTLSAddress values must fully describe how (and
        when) such names are to be resolved to IP addresses and vice
        versa.

This textual convention SHOULD NOT be used directly in object
        definitions since it restricts addresses to a specific
        format.  However, if it is used, it MAY be used either on its
        own or in conjunction with TransportAddressType or
        TransportDomain as a pair.

When this textual convention is used as a syntax of an index
        object, there may be issues with the limit of 128
        sub-identifiers specified in SMIv2 (STD 58).  It is RECOMMENDED
        that all MIB documents using this textual convention make
        explicit any limitations on index component lengths that
        management software must observe.  This may be done either by

including SIZE constraints on the index components or by
        specifying applicable constraints in the conceptual row
        DESCRIPTION clause or in the surrounding documentation."

1) for IPv4, the value is converted into a
                     decimal-dotted quad address (e.g., '192.0.2.1').

2) for IPv6 addresses, the value is converted into a
                     32-character all lowercase hexadecimal string

    DESCRIPTION
        "This table is used by a (D)TLS server to map the (D)TLS
        client's presented X.509 certificate to a tmSecurityName.

On an incoming (D)TLS/SNMP connection, the client's presented
        certificate must either be validated based on an established
        trust anchor, or it must directly match a fingerprint in this
        table.  This table does not provide any mechanisms for
        configuring the trust anchors; the transfer of any needed
        trusted certificates for path validation is expected to occur
        through an out-of-band transfer.

Once the certificate has been found acceptable (either by path
        validation or directly matching a fingerprint in this table),
        this table is consulted to determine the appropriate
        tmSecurityName to identify with the remote connection.  This
        is done by considering each active row from this table in
        prioritized order according to its snmpTlstmCertToTSNID value.
        Each row's snmpTlstmCertToTSNFingerprint value determines
        whether the row is a match for the incoming connection:

1) If the row's snmpTlstmCertToTSNFingerprint value
               identifies the presented certificate, then consider the
               row as a successful match.

2) If the row's snmpTlstmCertToTSNFingerprint value
               identifies a locally held copy of a trusted CA
               certificate and that CA certificate was used to
               validate the path to the presented certificate, then
               consider the row as a successful match.

Once a matching row has been found, the
        snmpTlstmCertToTSNMapType value can be used to determine how
        the tmSecurityName to associate with the session should be
        determined.  See the snmpTlstmCertToTSNMapType column's
        DESCRIPTION for details on determining the tmSecurityName
        value.  If it is impossible to determine a tmSecurityName from
        the row's data combined with the data presented in the

certificate, then additional rows MUST be searched looking for
        another potential match.  If a resulting tmSecurityName mapped
        from a given row is not compatible with the needed
        requirements of a tmSecurityName (e.g., VACM imposes a
        32-octet-maximum length and the certificate derived
        securityName could be longer), then it must be considered an
        invalid match and additional rows MUST be searched looking for
        another potential match.

If no matching and valid row can be found, the connection MUST
        be closed and SNMP messages MUST NOT be accepted over it.

Missing values of snmpTlstmCertToTSNID are acceptable and
        implementations should continue to the next highest numbered
        row.  It is recommended that administrators skip index values
        to leave room for the insertion of future rows (for example,
        use values of 10 and 20 when creating initial rows).

Users are encouraged to make use of certificates with
        subjectAltName fields that can be used as tmSecurityNames so
        that a single root CA certificate can allow all child
        certificate's subjectAltName to map directly to a
        tmSecurityName via a 1:1 transformation.  However, this table
        is flexible to allow for situations where existing deployed
        certificate infrastructures do not provide adequate
        subjectAltName values for use as tmSecurityNames.
        Certificates may also be mapped to tmSecurityNames using the
        CommonName portion of the Subject field.  However, the usage
        of the CommonName field is deprecated and thus this usage is
        NOT RECOMMENDED.  Direct mapping from each individual
        certificate fingerprint to a tmSecurityName is also possible
        but requires one entry in the table per tmSecurityName and
        requires more management operations to completely configure a
        device."

        SNMP-TARGET-MIB.  It extends the SNMP-TARGET-MIB's

snmpTargetAddrTable so that the client can verify that the
        correct server has been reached.  This verification can use
        either a certificate fingerprint, or an identity
        authenticated via certification path validation.

If there is an active row in this table corresponding to the
        entry in the SNMP-TARGET-MIB that was used to establish the
        connection, and the row's snmpTlstmAddrServerFingerprint
        column has non-empty value, then the server's presented
        certificate is compared with the
        snmpTlstmAddrServerFingerprint value (and the
        snmpTlstmAddrServerIdentity column is ignored).  If the
        fingerprint matches, the verification has succeeded.  If the
        fingerprint does not match, then the connection MUST be
        closed.

If the server's presented certificate has passed
        certification path validation [RFC5280] to a configured
        trust anchor, and an active row exists with a zero-length
        snmpTlstmAddrServerFingerprint value, then the
        snmpTlstmAddrServerIdentity column contains the expected
        host name.  This expected host name is then compared against
        the server's certificate as follows:

- Implementations MUST support matching the expected host
          name against a dNSName in the subjectAltName extension
          field and MAY support checking the name against the
          CommonName portion of the subject distinguished name.

- The '*' (ASCII 0x2a) wildcard character is allowed in the
          dNSName of the subjectAltName extension (and in common
          name, if used to store the host name), but only as the
          left-most (least significant) DNS label in that value.
          This wildcard matches any left-most DNS label in the
          server name.  That is, the subject *.example.com matches
          the server names a.example.com and b.example.com, but does
          not match example.com or a.b.example.com.  Implementations
          MUST support wildcards in certificates as specified above,
          but MAY provide a configuration option to disable them.

- If the locally configured name is an internationalized
          domain name, conforming implementations MUST convert it to
          the ASCII Compatible Encoding (ACE) format for performing
          comparisons, as specified in Section 7 of [RFC5280].

If the expected host name fails these conditions then the
        connection MUST be closed.

If there is no row in this table corresponding to the entry
        in the SNMP-TARGET-MIB and the server can be authorized by
        another, implementation-dependent means, then the connection
