TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
Set to 'true' to enable global SNMP notification for DoS prevention feature. Setting the object to 'false' will disable SNMP notifications.
1.3.6.1.4.1.171.17.59.1.2.1
Counter64 (0..18446744073709551615)
This object indicates the total dropped packets due to DoS attack in the past 5 minutes.
1.3.6.1.4.1.171.17.59.1.2.2
IpAddress SIZE (4)
If the DoS packet is from the end station, represent the IP address of attacker; otherwise represent the router's IP.
1.3.6.1.4.1.171.17.59.1.2.3
Unsigned32
This object indicates the attacked port number.
1.3.6.1.4.1.171.17.59.1.2.4
InetAddressType0 = unknown1 = ipv42 = ipv63 = ipv4z4 = ipv6z16 = dnsA value that represents a type of Internet address. unknown(0) An unknown address type. This value MUST be used if the value of the corresponding InetAddress object is a zero-length string. It may also be used to indicate an IP address that is not in one of the formats defined below. ipv4(1) An IPv4 address as defined by the InetAddressIPv4 textual convention. ipv6(2) An IPv6 address as defined by the InetAddressIPv6 textual convention. ipv4z(3) A non-global IPv4 address including a zone index as defined by the InetAddressIPv4z textual convention. ipv6z(4) A non-global IPv6 address including a zone index as defined by the InetAddressIPv6z textual convention. dns(16) A DNS domain name as defined by the InetAddressDNS textual convention. Each definition of a concrete InetAddressType value must be accompanied by a definition of a textual convention for use with that InetAddressType. To support future extensions, the InetAddressType textual convention SHOULD NOT be sub-typed in object type definitions. It MAY be sub-typed in compliance statements in order to require only a subset of these address types for a compliant implementation. Implementations must ensure that InetAddressType objects and any dependent objects (e.g., InetAddress objects) are consistent. An inconsistentValue error must be generated if an attempt to change an InetAddressType object would, for example, lead to an undefined InetAddress value. In particular, InetAddressType/InetAddress pairs must be changed together if the address type changes (e.g., from ipv6(2) to ipv4(1)). · Integer32
A value that represents a type of Internet address. unknown(0) An unknown address type. This value MUST be used if the value of the corresponding InetAddress object is a zero-length string. It may also be used to indicate an IP address which is not in one of the formats defined below. ipv4(1) An IPv4 address as defined by the InetAddressIPv4 textual convention. ipv6(2) An IPv6 address as defined by the InetAddressIPv6 textual convention. dns(16) A DNS domain name as defined by the InetAddressDNS textual convention.
1.3.6.1.4.1.171.17.59.1.2.5
InetAddressDenotes a generic Internet address. An InetAddress value is always interpreted within the context of an InetAddressType value. Every usage of the InetAddress textual convention is required to specify the InetAddressType object that provides the context. It is suggested that the InetAddressType object be logically registered before the object(s) that use the InetAddress textual convention, if they appear in the same logical row. The value of an InetAddress object must always be consistent with the value of the associated InetAddressType object. Attempts to set an InetAddress object to a value inconsistent with the associated InetAddressType must fail with an inconsistentValue error. When this textual convention is used as the syntax of an index object, there may be issues with the limit of 128 sub-identifiers specified in SMIv2, STD 58. In this case, the object definition MUST include a 'SIZE' clause to limit the number of potential instance sub-identifiers; otherwise the applicable constraints MUST be stated in the appropriate conceptual row DESCRIPTION clauses, or in the surrounding documentation if there is no single DESCRIPTION clause that is appropriate.

INTEGER1 = tcpAndUdp2 = tcpOnly3 = udpOnly · Integer32
This object indicates the type of packets that will be checked when blat attack prevention function is enabled. 'tcpAndUdp' - both TCP and UDP packets will be checked. 'tcpOnly' - TCP packets will be checked. 'udpOnly' - UDP packets will be checked.
1.3.6.1.4.1.171.17.59.1.3
Index: esDoSPrevCtrlAttackType
A table includes the settings of all DoS prevention types supported by the Switch. Note: the special attack type 'all' is not included in this table.

Note that a particular agent may support only certain DoS attack types. Thus, the valid values of this object are project dependent. An agent may respond with an error (e.g., 'inconsistentValue ') to a management SET operation which attempts to modify the value to one which is not supported by the managed device. · Integer32
This object indicates the DoS attack type.
1.3.6.1.4.1.171.17.59.1.3.1.2
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
This object indicates the state of the DoS attack type. Setting this object to 'false' will reset other columnar objects in the same row.
1.3.6.1.4.1.171.17.59.1.3.1.3
INTEGER1 = drop2 = redirect · Integer32
This object indicates the action for the DoS prevention type. If this object is set to 'redirect' and esDoSPrevCtrlEnabled is 'true', the configuration will not take effect until a valid redirect port (esDoSPrevCtrlRedirectPort) is specified. If redirect port is not valid, the switch behaves same as 'drop' is set.
1.3.6.1.4.1.171.17.59.1.3.1.4
InterfaceIndexOrZeroThis textual convention is an extension of the InterfaceIndex convention. The latter defines a greater than zero value used to identify an interface or interface sub-layer in the managed system. This extension permits the additional value of zero. the value zero is object-specific and must therefore be defined as part of the description of any object which uses this syntax. Examples of the usage of zero might include situations where interface was unknown, or when none or all interfaces need to be referenced. (0..2147483647) · Integer32 · hint d
This object indicates the port to which the attacking packet will be redirected. A value of 0 means redirect port is unspecified. This object can only be modified for entries whose value of esDoSPrevCtrlEnabled is 'true' and esDoSPrevCtrlActionType is 'redirect'. Otherwise, inconsistentValue error will be returned.
1.3.6.1.4.1.171.17.59.1.3.1.5
Unsigned32 (0..8)
This object configures the priority for the redirected attacking packets. Valid priority values are from 0 to 7. A value of 8 indicates that the original priority will not be changed when the packet is redirected. This object can only be modified for entries whose value of esDoSPrevCtrlEnabled is 'true', esDoSPrevCtrlActionType is 'redirect' and esDoSPrevCtrlRedirectPort is specified. Otherwise, inconsistentValue error will be returned.
1.3.6.1.4.1.171.17.59.1.3.1.6
Unsigned32 (0..100000000) · kbps
This object indicates the rate-limit (kilobit per second) for redirecting DoS attacking packets. The valid range and granularity is project dependent. A value of 0 indicates that there is no limit for redirecting DoS attacking packets. This object can only be modified for entries whose value of esDoSPrevCtrlEnabled is 'true', esDoSPrevCtrlActionType is 'redirect' and esDoSPrevCtrlRedirectPort is specified. Otherwise, inconsistentValue error will be returned.
1.3.6.1.4.1.171.17.59.1.4

The table contains the counters of DoS prevention types supported by the Switch. This table only contains one entry of attack type is 'all' if per DoS-type counters is not supported.
