Finding Feature Information
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.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.
Prerequisites for Memory Pool—SNMP Notification Support
Before you can compile CISCO-ENHANCED-MEMPOOL-MIB, you need to compile the following MIBs in the order listed:
SNMPv2-SM (SNMP configuration MIB)
SNMPv2-TC (SNMP configuration MIB)
SNMPv2-CONF (SNMP configuration MIB)
SNMP-FRAMEWORK-MIB (SNMP configuration MIB)
CISCO-SMI (SNMP configuration MIB)
ENTITY-MIB (core MIB)
CISCO-ENHANCED-MEMPOOL-MIB (infrastructure MIB)
All MIBs used on Cisco devices are available at http://www.cisco.com/go/mibs.
Restrictions for Memory Pool—SNMP Notification Support
Access to the MIB is restricted to a read-only level.
Information About Memory Pool—SNMP Notification Support
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. Lately, 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).
How to Enable Memory Pool—SNMP Notification Support
1.

DETAILED STEPS
Configuration Examples for Memory Pool—SNMP Notification Support
Enabling Memory Pool—SNMP Notification Support Example
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.
