Memory Pool--SNMP Notification SupportLast Updated: August 17, 2011
This feature adds command-line interface (CLI) commands to enable SNMP notifications for the Cisco Enhanced Memory Pool MIB (CISCO-ENHANCED-MEMPOOL-MIB). Finding Support Information for Platforms and Cisco IOS Software ImagesUse Cisco Feature Navigator to find information about platform support and Cisco IOS software image support. Access Cisco Feature Navigator at http://www.cisco.com/go/fn . You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear.
Finding Feature InformationYour software release may not support all the features documented in this module.

Prerequisites for Memory Pool--SNMP Notification SupportBefore 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 . Restrictions for Memory Pool--SNMP Notification SupportAccess to the MIB is restricted to a read-only level. Information About Memory Pool--SNMP Notification SupportThe 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 routers that may have a large number of line cards. Beginning in Cisco IOS Release 12.3(4)T, 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 SupportSUMMARY STEPS
DETAILED STEPS Configuration Examples for Memory Pool--SNMP Notification SupportEnabling Memory Pool--SNMP Notification Support ExampleIn 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: Router(config)# snmp-server enable traps memory bufferpeak Router(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.
