Memory Pool—SNMP Notification Support

This feature adds CLI commands to enable SNMP notifications for the Cisco Enhanced Memory Pool MIB (CISCO-ENHANCED-MEMPOOL-MIB).

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 ActionPurpose
    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 5exit


    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.
