Note that only the processor pool is required to be supported by all devices. Support for other pool types is dependent on the device being managed. processorMemory - processor associated heap memory. ioMemory - shared memory for buffer data and controller descriptor blocks. pciMemory - Peripheral Component Interconnect bus memory which is visible to all devices on the PCI buses in a platform. fastMemory - memory defined by the particular platform for speed critical applications. multibusMemory - memory present on some platforms that is used as a fallback pool. interruptStackMemory - memory for allocating interrupt stacks. It is usually allocated from heap. processStackMemory - memory for allocating process stacks. It is usually allocated from heap. localExceptionMemory - memory reserved for processing a system core dump. virtualMemory - memory used to increase available RAM. reservedMemory - memory used for packet headers, particle headers and particles. imageMemory - memory which corresponds to the image file system. asicMemory - Application Specific Integrated Circuit memory. posixMemory - Heap memory associated with posix style processes in ion. · Integer32

The type of memory pool for which this entry contains information.

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 (0..255) · OCTET STRING · hint 255t

A textual name assigned to the memory pool. This object is suitable for output to a human operator, and may also be used to distinguish among the various pool types.

AutonomousTypeRepresents an independently extensible type identification value. It may, for example, indicate a particular sub-tree with further MIB definitions, or define a particular type of protocol or hardware. · OBJECT IDENTIFIER

An indication of the platform-specific memory pool type. The associated instance of cempMemPoolType is used to indicate the general type of memory pool. If no platform specific memory hardware type identifier exists for this physical entity, or the value is unknown by this agent, then the value { 0 0 } is returned.

CempMemPoolIndexOrNoneThis textual convention is an extension of the CempMemPoolIndex. The latter defines a value greater than zero to identify a memory pool in a particular physical entity. 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 memory pool was unknown, or when none or all memory pools need to be referenced. (0..2147483647) · Integer32

Indicates whether or not this memory pool has an alternate pool configured. Alternate pools are used for fallback when the current pool runs out of memory. If an instance of this object has a value of zero, then this pool does not have an alternate. Otherwise the value of this object is the same as the value of cempMemPoolType of the alternate pool.

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

Indicates whether or not cempMemPoolUsed, cempMemPoolFree, cempMemPoolLargestFree and cempMemPoolLowestFree in this entry contain accurate data. If an instance of this object has the value false (which in and of itself indicates an internal error condition), the values of these objects in the conceptual row may contain inaccurate information (specifically, the reported values may be less than the actual values).

This object represents the upper 32-bits of cempMemPoolUsed. This object needs to be supported only if the used bytes in the memory pool exceeds 32-bits, otherwise this object value would be set to 0.

CounterBasedGauge64The CounterBasedGauge64 type represents a non-negative integer, which may increase or decrease, but shall never exceed a maximum value, nor fall below a minimum value. The maximum value can not be greater than 2^64-1 (18446744073709551615 decimal), and the minimum value can not be smaller than 0. The value of a CounterBasedGauge64 has its maximum value whenever the information being modeled is greater than or equal to its maximum value, and has its minimum value whenever the information being modeled is smaller than or equal to its minimum value. If the information being modeled subsequently decreases below (increases above) the maximum (minimum) value, the CounterBasedGauge64 also decreases (increases). Note that this TC is not strictly supported in SMIv2, because the 'always increasing' and 'counter wrap' semantics associated with the Counter64 base type are not preserved. It is possible that management applications which rely solely upon the (Counter64) ASN.1 tag to determine object semantics will mistakenly operate upon objects of this type as they would for Counter64 objects.

Indicates the total number of permanent buffers in the pool on the physical entity.

Unsigned32

Indicates the initial number of temporary buffers in the pool on the physical entity. This object instructs the system to create this many number of temporary extra buffers, just after a system restart. A change in this object will be effective only after a system restart.

Gauge32

Indicates the total number of buffers (include allocated and free buffers) in the buffer pool on the physical entity.

Indicates the peak number of buffers in pool on the physical entity.

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
