SNMP Parameters

Enables and disables device management through SNMP.

Defines the device's local (LAN) UDP port used for SNMP Get/Set commands.

The range is 100 to 3999. The default port is 161.

Note: For the parameter to take effect, a device restart is required.

Defines the 'alias' name object for the physical entity as specified by a network manager, and provides a non-volatile 'handle' for the physical entity.
The valid range is a string of up to 255 characters.

Defines the user-assigned asset tracking identifier object for the device's chassis as specified by OVOC, and provides non-volatile storage of this information.
The valid range is a string of up to 255 characters.

Defines the textual name of the interface. The value is equal to the ifAlias SNMP MIB object.
The valid range is a string of up to 64 characters.

Enables the device to send NAT keep-alive traps to the port of the SNMP network management station (e.g., AudioCodes OVOC). This is used for NAT traversal, and allows SNMP communication with OVOC management platform, located in the WAN, when the device is located behind NAT. It is needed to keep the NAT pinhole open for the SNMP messages sent from OVOC to the device. The device sends the trap periodically - every 9/10 of the time configured by the NATBindingDefaultTimeout parameter. The trap that is sent is acKeepAlive. For more information, refer to the SBC-Gateway Series SNMP Alarm Reference Guide.

To configure the port number, use the KeepAliveTrapPort parameter.

Note: For the parameter to take effect, a device restart is required.

Defines the port of the SNMP network management station to which the device sends keep-alive traps.

The valid range is 0 - 65534. The default is port 162.

To enable NAT keep-alive traps, use the [SendKeepAliveTrap] parameter.

Enables the sending of the SNMP trap event acPerformanceMonitoringThresholdCrossing, which is sent every time the threshold (high or low) of a Performance Monitored object (e.g., acPMSIPSBCAttemptedCallsTable) is crossed.

Note: Once enabled, you can change the low and high threshold values per performance monitored object. For more information, refer to the SBC-Gateway Series SNMP Alarm Reference Guide.

Defines the maximum duration (in seconds) of an SBC call for it to be considered a short call and included in the performance monitoring count for short calls (shortCallsCounterTotal and shortCallsCounter). The duration must be less than or equal to the configured value for the call to be considered a short call.

The valid value is 0 to 60. The default is 2. A value of 0 indicates calls of zero duration, which are calls that do not pass the device's Classification, Manipulation or Routing stages.

Defines the minimum duration (in minutes) of an SBC call for it to be considered a long call and included in the performance monitoring count for long calls (longCallsCounterTotal and longCallsCounter). The duration must be greater than or equal to the configured value for the call to be considered a long call.

The valid value is 0 to 60. The default is 30. A value of 0 indicates calls of zero duration, which are calls that do not pass the device's Classification, Manipulation or Routing stages.

Defines the description of the input alarm.

Defines the severity of the input alarm.

Defines the maximum number of historical alarms that can be displayed in the Alarm History table. The parameter can be controlled by the Config Global Entry Limit MIB (located in the Notification Log MIB).

The valid range is 50 to 1000. The default is 500.

Note: For the parameter to take effect, a device restart is required.

Defines the maximum number of active alarms that can be displayed in the Active Alarms table.

When the table reaches this user-defined maximum capacity (i.e., full), the device sends the SNMP trap event, acActiveAlarmTableOverflow. If the table is full and a new alarm is raised by the device, the new alarm is not displayed in the table.

The valid range is 100 to 1000. The default is 250.

For more information on the Active Alarms table, see Viewing Active Alarms.

Note:

Enables the device to store the alarms of the Alarms History table on its flash memory. When enabled, the alarms are not deleted from table upon a device restart.

For more information, see Storing Alarms History on Flash.

Note:

Defines how often (in minutes) the device saves the alarms of the Alarms History table to its flash memory.

The valid value range is 1 to 50,000. The default is 1,440 (24 hours).

For more information, see Storing Alarms History on Flash.

Defines the contextEngineID as mentioned in RFC 3411. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the snmpEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName).

Note:

Defines the SNMP engine ID for SNMPv2/SNMPv3 agents. This is used for authenticating a user attempting to access the SNMP agent on the device.

The ID can be a string of up to 36 characters. The default is 00:00:00:00:00:00:00:00:00:00:00:00 (12 Hex octets characters). The provided key must be set with 12 Hex values delimited by a colon (":") in the format xx:xx:...:xx. For example, 00:11:22:33:44:55:66:77:88:99:aa:bb

Note:

Defines an FQDN for IPv4 address resolution of the remote host used as an SNMP Trap Manager to receive traps sent by the device. The device sends the traps to the DNS-resolved IP address.

The valid range is a string of up to 99 characters.

For more information, see Configuring an SNMP Trap Destination with FQDN.

Defines an FQDN for IPv6 address resolution of the remote host used as an SNMP Trap Manager to receive traps sent by the device. The device sends the traps to the DNS-resolved IP address.

The valid range is a string of up to 99 characters.

For more information, see Configuring an SNMP Trap Destination with FQDN.

Enables the device to send an SNMP trap to notify of Web user activities in the Web interface. The activities to report are configured by the [ActivityListToLog] parameter (see Reporting Management User Activities).

Assigns an IPv4 IP Interface (configured in the IP Interfaces table - see Configuring IP Network Interfaces) to the SNMP application for SNMP over IPv4.

By default, the OAMP IP Interface is assigned to SNMP over IPv4.

For more information, see Configuring SNMP Interfaces.

Assigns an IPv6 IP Interface (configured in the IP Interfaces table - see Configuring IP Network Interfaces) to the SNMP application for SNMP over IPv6.

For more information, see Configuring SNMP Interfaces.

Disables the sending of the Authentication Failure SNMP trap (authenticationFailure, OID 1.3.6.1.6.3.1.1.5.5).

Defines a read-only SNMP community string. Up to five read-only community strings can be configured. For more information, see Configuring SNMP Community Strings.

Note:

Defines a read-write SNMP community string. Up to five read-write community strings can be configured. For more information, see Configuring SNMP Community Strings.
