The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This feature adds Cisco command line interface commands to enable Simple Network Management Protocol (SNMP) notifications for the Cisco Enhanced Memory Pool MIB (CISCO-ENHANCED-MEMPOOL-MIB).
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Before you can compile CISCO-ENHANCED-MEMPOOL-MIB, you need to compile the following MIBs in the order listed:
All MIBs used on Cisco devices are available through Cisco.com at http://www.cisco.com/go/mibs.
Access to the MIB is restricted to a read-only level.
The CISCO-ENHANCED-MEMPOOL-MIB module describes SNMP objects that enable users to remotely monitor the memory pool statistics of all physical entities, such as line cards and route processors, in a managed device. This is particularly useful for high-end devices that may have a large number of line cards. The MIB has been enhanced to provide buffer pool and buffer cache statistics.
In addition to the statistics provided by the MIB, SNMP notifications (traps or informs) can be configured to be sent when the maximum number of memory buffers changes (in other words, when a new buffer peak is reached).
Perform this task to enable memory pool for SNMP notification support.
In the following example, all available memory-related SNMP notifications are enabled and configured to be sent as informs to the host myhost.cisco.com using the community string public:
Device(config)# snmp-server enable traps memory bufferpeak Device(config)# snmp-server host myhost.cisco.com informs version 3 public memory
Note that as of this release, only the buffer peak memory notification type is available. Additional memory notification type keywords may be added in future releases.
