Description: Monitors memory pool statistics across all physical entities (line cards, route processors) with utilization data at 1-minute, 5-minute, and 10-minute intervals.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCO-ENHANCED-MEMPOOL-MIB with a free 30-day trial of IPNetwork Monitor.

What Is CISCO-ENHANCED-MEMPOOL-MIB?

CISCO-ENHANCED-MEMPOOL-MIB monitors memory pool statistics across all physical entities on a managed Cisco system, such as route processors and line cards, extending earlier memory-pool MIBs with support for multiple historical intervals. It exposes cempMemPoolTable, giving per-entity, per-pool-type memory statistics including used, free, largest-free, and lowest-free-watermark values, indexed against the entity's identity. This is a direct hardware/software resource-health MIB: it lets an operator monitor memory (RAM) utilization on individual cards and processors, catching memory leaks, fragmentation (via cempMemPoolLargestFree shrinking), or low-memory conditions before they cause instability or crashes. It depends on ENTITY-MIB, since cempMemPoolTable entries are indexed by the physical entity index defined there. It is deployed across Cisco routers and switches with modular/multi-card chassis to track memory health per line card and route processor over 1-, 5-, and 10-minute intervals, making cisco-enhanced-mempool-mib a standard reference for that kind of resource-health tracking.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ENHANCED-MEMPOOL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco modular router
Cisco modular switch with line cards/route processors
Cisco modular routers and switches (route processors and line cards)

Monitoring Examples

An operator would poll cempMemPoolTable/cempMemPoolEntry per cempMemPoolIndex to track cempMemPoolUsed versus cempMemPoolFree for each cempMemPoolName (e.g., processor memory, I/O memory) on every physical entity, watching cempMemPoolLowestFree for a downward trend indicating a slow memory leak. A shrinking cempMemPoolLargestFree despite stable cempMemPoolFree would reveal memory fragmentation on a specific line card. This lets operators identify a card headed toward an out-of-memory condition well before it actually fails.

What Can Be Monitored

memory used per pool
memory free per pool
largest free memory block
lowest free memory watermark
memory pool type and name per entity

How to Use in IPNetwork Monitor

Example using cempMemPoolAllocHit OID:

Select a Cisco modular router or switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cempMemPoolAllocHit into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. Indicates the number of successful allocations from the memory pool. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
C32 cempMemBufferCacheHit	1.3.6.1.4.1.9.9.221.1.1.3.1.4	Counter32	read-only	Indicates the number of buffers successfully allocated from the cache pool.
C32 cempMemBufferCacheMiss	1.3.6.1.4.1.9.9.221.1.1.3.1.5	Counter32	read-only	Indicates the number of times a buffer has been requested, but no buffers were available in the cache pool.
cempMemBufferCachePoolEntry	1.3.6.1.4.1.9.9.221.1.1.3.1		not-accessible	Each entry represents one of the cache buffer pools available in the system and it contains the parameters configured for it. Note : cempMemBufferCachePoolTable has a sparse dependency with cempMemBufferPoolTable (i.e all the entires in cempMemBufferPoolTable need not have an entry in cempMemBufferCachePoolTable.
cempMemBufferCachePoolTable	1.3.6.1.4.1.9.9.221.1.1.3		not-accessible	A table that lists the cache buffer pools configured on a managed system. 1)To provide a noticeable performance boost, Cache Pool can be used. A Cache Pool is effectively a lookaside list of free buffers that can be accessed quickly. Cache Pool is tied to Buffer Pool. 2)Cache pools can optionally have a threshold value on the number of cache buffers used in a pool. This can provide flow control management by having a implementation specific approach such as invoking a vector when pool cache rises above the optional threshold set for it on creation.
U32 cempMemBufferCacheSize	1.3.6.1.4.1.9.9.221.1.1.3.1.1	Unsigned32	read-only	Indicates the number of buffers in the cache pool on the physical entity.
G32 cempMemBufferCacheThreshold	1.3.6.1.4.1.9.9.221.1.1.3.1.6	Gauge32	read-only	Indicates the threshold limit for number of cache buffers used(cempMemBufferCacheUsed).

T/F cempMemBufferDynamic	1.3.6.1.4.1.9.9.221.1.1.2.1.4	TruthValue	read-only	Boolean poolDynamic; if TRUE, the number of buffers in the pool is adjusted (adding more packet buffers or deleting excesses) dynamically by the background process. If FALSE, the number of buffers in the pool is never adjusted, even if it falls below the minimum, or to zero.

C32 cempMemBufferFailures	1.3.6.1.4.1.9.9.221.1.1.2.1.21	Counter32	read-only	The number of failures to grant a buffer to a requester due to reasons other than insufficient memory. For example, in systems where there are different execution contexts, it may be too expensive to create new buffers when running in certain contexts. In those cases it may be preferable to fail the request.
G32 cempMemBufferFree	1.3.6.1.4.1.9.9.221.1.1.2.1.11	Gauge32	read-only	Indicates the current number of free buffers in the buffer pool on the physical entity. Note that the cempMemBufferFree is less than or equal to cempMemBufferTotal.

C32 cempMemBufferFreeMiss	1.3.6.1.4.1.9.9.221.1.1.2.1.15	Counter32	read-only	Indicates the number of unsuccessful attempts to free/deallocate a buffer from the buffer pool. For example, this could be due to ownership errors where the application that did not assign the buffer is trying to free it.

cempMemBufferPoolTable	1.3.6.1.4.1.9.9.221.1.1.2		not-accessible	Entries in this table define entities (buffer pools in this case) which are contained in an entity (memory pool) defined by an entry from cempMemPoolTable. -- Basic Pool Architecture -- 1)Pools are classified as being either Static or Dynamic. Static pools make no attempt to increase the number of buffers contained within them if the number of free buffers (cempMemBufferFree) are less than the number of minimum buffers (cempMemBufferMin). With Dynamic pools, the pool attempts to meet the demands of its users. 2)Buffers in a pool are classified as being either Permanent or Temporary. Permanent buffers, as their name suggests, are always in the pool and are never destroyed unless the number of permanent buffers (cempMemBufferPermanent) is changed. Temporary buffers are transient buffers that are created in dynamic pools whenever the free count (cempMemBufferFree) of buffers in the pool drops below the minimum (cempMemBufferMin). 3)Buffers pools are classified as either Public or Private. Public pools are available for all users to allocate buffers from. Private pools are primarily used by interface drivers.
U32 cempMemBufferSize	1.3.6.1.4.1.9.9.221.1.1.2.1.5	Unsigned32	read-write	Indicates the size of buffer element in number of bytes 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.
C32 cempMemBufferTrim	1.3.6.1.4.1.9.9.221.1.1.2.1.19	Counter32	read-only	The number of buffers that have been trimmed from the pool when the number of free buffers (cempMemBufferFree) exceeded the number of max allowed buffers(cempMemBufferMax).
