Steps for migrating the PW.SRC and SNMPTRAP.DEST files

This topic describes the steps of migrating the PW.SRC and SNMPTRAP.DEST files to the SNMPD.CONF file.

Perform the following steps to migrate the PW.SRC and SNMPTRAP.DEST files to the SNMPD.CONF file:

1. For each community name defined in the the PW.SRC file, create an SNMP_COMMUNITY statement in the SNMPD.CONF file. This identifies the community names defined to the agent.

   _______________________________________________________________

2. Create TARGET_ADDRESS entries to identify the address range permitted to use a particular community name. For each SNMP_COMMUNITY entry and for each range of addresses for which it is used, create a TARGET_ADDRESS entry. The TARGET_ADDRESS entries refer to related TARGET_PARAMETERS entries.

   _______________________________________________________________

3. Create TARGET_PARAMETERS entries to identify the security model (SNMPv1 or SNMPv2c) to be used with the address on the corresponding TARGET_ADDRESS entries.

4. Define the following entries to determine which SNMP communities get access to which pieces of data and the type of access that they are allowed:

   VACM_GROUP

   Specify one entry for each security model (in this case SNMPv1 or SNMPv2c) and use the community names from the PW.SRC file.

   VACM_VIEW

   Specify one entry for each set of MIB object identifiers that you want to protect.

   VACM_ACCESS

   Specify one entry that ties together the VACM_GROUP and VACM_VIEW entries and defines each group/view permission. You can define the group’s permission to read, write, and receive notifications for the defined views.

   _______________________________________________________________

5. To continue sending notifications, convert the entries in the SNMPTRAP.DEST file to entries in the SNMPD.CONF file.
   • Add one NOTIFY entry for type TRAP.
   • Add one TARGET_ADDRESS statement for each manager that receives a TRAP.
   • Optionally, configure a TARGET_PARAMETERS entry to identify the message model used in sending notifications to particular destinations. The default is SNMPv1, or specify SNMPv2c. Encryption and authentication are not used.
