Configure SNMP System and Agent Parameters

High level SNMP identification is configured by all SNMP users. This information includes system-level management Information, system contact information, system name and location information and is applicable to both SNMPv1v2 and SNMPv3 deployments. The Oracle® Communications Session Border Controller MIB Reference Guide includes detail on SNMP data.

1. Access the system-config configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# system
   ORACLE(system)# system-config
   ORACLE(system-config)# 

2. Type select to begin editing the system-config object.

   ORACLE(system-config)# select
   ORACLE(system-config)#

3. mib-system-contact—Specifies contact information that is used within SBC MIB transactions. This value is a textual identification and usually contains information about the company system contact person.
4. mib-system-name—Specifies the identity of this SBC that is presented within MIB transactions, which is the FQDN of the node.
5. mib-system-location—Specifies the physical location of the SBC that is reported within MIB transactions. This parameter is reported when an SNMP GET is issued by the NMS for the MIB-II sysLocation variable. This parameter has no direct relation to the location field in the system configuration element.
6. snmp-agent-mode —Select the operating mode of the SNMP agent.
   • v1v2—(Default) The SNMP agent supports SNMPv1 and SNMPv2. Configure the The snmp-community and trap-receiver elements only.
   • v3—The SNMP agent supports SNMPv3, but can also support SNMPv2 through snmp-user-group element configuration.

     Note:

     To create a v2 snmp-user-group, you configure the mp-model parameter to v1v2 and leave the community-string parameter blank. The system then matches hosts' SNMP version 2 community strings with the user-list parameter value. You also configure snmp-user-entry and snmp-address-entry elements to complete your v2 group configuration.
7. snmp-engine-id-suffix—Uniquely identifies the SNMP Engine by specifying a unique suffix for the SNMPEngineID. This attribute is optional.
8. snmp-rate-limit—Set the rate limit for SNMP traffic to prevent SNMP from interfering with service traffic. The range is from 0 to 9999 packets per second. The default is zero, which applies no limit.
9. lower-snmp-priority—This option allows you to lower the priority of the SNMP processing task to prevent SNMP from interfering with service processing.

   ORACLE(system-config)options +lower-snmp-priority=enabled

   If you type the option without the plus sign, you overwrite any previously configured options. To append the new option to the options list, prepend the new option with a plus sign as shown in the previous example.

10. Type done to save your configuration.
