Sending SNMP traps

Server and Cluster Administration Guide for Hitachi NAS Platform

Part Number
A trap is unsolicited information that the SNMP agent sends to a manager. The trap enables the agent to alert the manager to an unusual system event. The SNMP agent supports the following set of traps:
  • AuthenticationFailure. Indicates that the SNMP agent received a request from an unauthorized manager. Either the manager used an incorrect community name or the agent has been set up to deny access to the manager.
  • ColdStart. Indicates that the SNMP agent has started or been restarted.
  • LinkUp.Indicates that the status of an Ethernet link has changed from Down to Up.
Note: SNMP v1 traps are not defined as objects within the MIB tree.

    • Information Alerts: The specified component is operating normally and is not displaying an alarm condition.
    SNMP Traps
    Send Traps to Port Enter the port number that the server uses to send traps. The default port number is 162.
    Send traps upon authentication failure (HNAS server only) Select this check box if the SNMP agent is to send a trap in the event of an authentication failure (caused, for example, by the SNMP host using an incorrect community string when formulating a request).
    Trap Recipients In this area, enter the hosts to which this server will send traps.

    In the Host field, enter the IP address of an SNMP host to associate with each community. If the system has been set up to work with a name server, you can type the name of the SNMP manager host rather than its address.

    In the Community field, type the name of the SNMP community (community names are case-sensitive).

    Click Add to save the information in the list.

    You can delete an entry in the list by selecting it and clicking the X.

    Note: The NAS server supports a maximum of 32 SNMP communities, each with up to 32 hosts. Existing trap destinations in excess of this number are honored, but it is not possible to add more than 32.
