Bias-Free Language

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.

Memory Pool—SNMP Notification Support

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).

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 https://cfnng.cisco.com/. 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:

  1. SNMPv2-SM (SNMP configuration MIB)

  2. SNMPv2-TC (SNMP configuration MIB)

  3. SNMPv2-CONF (SNMP configuration MIB)

  4. SNMP-FRAMEWORK-MIB (SNMP configuration MIB)

  5. CISCO-SMI (SNMP configuration MIB)

  6. ENTITY-MIB (core MIB)

  7. 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

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. snmp-server enable traps memory [bufferpeak ]
  4. snmp-server host {hostname | ip-address } [traps | informs ] [version {1 | 2c | 3 [auth | noauth | priv ]}] community-string [udp-port port ] [notification-type ] [vrf vrf-name ]
  5. exit

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Device> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 3

snmp-server enable traps memory [bufferpeak ]

Example:


Device(config)# snmp-server enable traps memory bufferpeak

Enables only buffer peak notifications (traps or informs) in the CISCO-ENHANCED-MEMPOOL-MIB.

Step 4

snmp-server host {hostname | ip-address } [traps | informs ] [version {1 | 2c | 3 [auth | noauth | priv ]}] community-string [udp-port port ] [notification-type ] [vrf vrf-name ]

Example:


Device(config)# snmp-server host NMS-host1.example.com community1 memory

Enables buffer peak notifications to be sent to the specified host.

Step 5

exit

Example:

Device(config)# exit

Exits global configuration mode and returns to privileged EXEC mode.

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.
