This mib defines the SNMP objects to report exceptions to north-bound NMS.
The devices implementing this MIB monitor the status of hardware and software services, and report any exceptions regarding these components. These hardware and software services could belong to the monitoring devices or other managed devices.
An exception is something abnormal that the system administrators should pay attention to. The criteria for what is an exception could vary by system and should be defined by the system administrators. Certain NM devices or applications may have pre-defined exceptions.
This MIB does not try to define exceptions. But rather it defines SNMP objects for devices to use SNMP notification as an exception reporting mechanism. Exceptions may be pre-defined or defined through other device management interface such as CLI, GUI, or HTTP.
The maximun number of records to keep in cderExceptionTable. New records will replace the old records on a first-in-first-out basis. A value of 0 indicates no history will be retained.
cderNotificationEnabled
1.3.6.1.4.1.9.9.224.1.1.2
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
Enable or disable exception notification via SNMP.
cderNotificationsSent
1.3.6.1.4.1.9.9.224.1.1.3
Counter32
The number of cderMonitoredExceptionEvent events.
If a NMS is receiving notifications, it can periodically poll this object to find out if any notifications were missed. In that case it could poll cderExceptionTable to find out missing exceptions.
cderNotificationsDropped
1.3.6.1.4.1.9.9.224.1.1.4
Counter32
The number of notifications dropped from the cderExceptionTable table. If the difference between two consecutive polls of this object is greater than cderMaxExceptionRecords, then it indicates the NMS will not be able to find missing exceptions. The solution is to either poll the cderExceptionTable more frequently or increase the size of the cderExceptionTable by setting cderMaxExceptionRecords.

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form.
To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279].
Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited.
The use of control codes should be avoided.
When it is necessary to represent a newline, the control code sequence CR LF should be used.
The use of leading or trailing white space should be avoided.
For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided.
For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding.
UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding.
Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416].
Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (1..32) · OCTET STRING · hint 255t
Identification for this exception. This object should uniquely identify the exception.
cderExcepHostAddressType
1.3.6.1.4.1.9.9.224.1.1.5.1.3
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
Represents the type of address stored in cderExcepHostAddress.
cderExcepHostAddress
1.3.6.1.4.1.9.9.224.1.1.5.1.4
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. SIZE (0..255) · OCTET STRING
Host device address where the exception happened.

Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (1..64) · OCTET STRING · hint 255t
A string that tells the system administrator about the priority of this exception. This string is provided to the snmp agent by the reporting service(s) which could be any services or applications on the device. The receiving NMS of this object should understand the string in order to utilize this object.
cderExcepTime
1.3.6.1.4.1.9.9.224.1.1.5.1.6
TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be
defined in the description of any object defined using this type.
If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks
