Configuring SNMP Trap Destinations

The SNMP Trap Destinations table lets you configure up to five SNMP trap destinations (managers) to receive traps sent by the device. The SNMP trap manager is defined by IP address or FQDN, and port. You can associate a trap destination with SNMPv2 users or specific SNMPv3 users. Associating a trap destination with SNMPv3 users sends encrypted and authenticated traps to the SNMPv3 destination. By default, traps are sent unencrypted using SNMPv2.

The following procedure describes how to configure SNMP trap destinations through the Web interface. You can also configure it through ini file [SNMPTrapDestinations] or CLI (configure system > snmp settings > trap-destinations).

➢ To configure SNMP trap destinations:
1. Open the SNMP Trap Destinations table (Setup menu > Administration tab > SNMP folder > SNMP Trap Destinations).
2. Click New; the following dialog box appears:

3. Configure an SNMP trap destination (manager) according to the parameters described in the table below.
4. Click Apply.
● Rows whose corresponding check boxes are cleared revert to default settings when you click Apply.
● To enable the sending of the trap event acPerformanceMonitoringThresholdCrossing, which is sent whenever a threshold (high or low) of a performance monitored SNMP MIB object is crossed, configure the ini file parameter [PM_EnableThresholdAlarms] to [1]. Once enabled, you can change its default low and high threshold values. For more information, see the SNMP Reference Guide for Gateways-SBCs-MSBRs.

SNMP Trap Destinations Table Parameters Description

Parameter

Description

'Index'

[SNMPTrapDestinations_Index]

Defines an index number for the new table row.

Note: Each row must be configured with a unique index.

'Name'

name

[SNMPTrapDestinations_Name]

Defines a descriptive name for the SNMP trap manager.

The valid value is a string of up to 31 characters.

'Address'

address

[SNMPTrapDestinations_Address]

Defines the address of the remote host used as the SNMP trap manager. The device sends its SNMP traps to this address.

The valid value includes one of the following:

■ IPv4 address in dotted-decimal notation (e.g., 108.10.1.255)
■ IPv6 address in colon-separated hexadecimal (e.g., 3ffe:1900:4545:3:200:f8ff:fe21:67cf)
■ Hostname or FQDN (e.g., mngr.corp.mycompany.com). The device sends the traps to the DNS-resolved IP address.

The default is 0.0.0.0 (i.e., not defined).

Note: If you are using a WebSocket tunnel connection between the device and OVOC, configure the parameter to the IP address mentioned in Configuring WebSocket Tunnel with OVOC

'Port'

port

[SNMPTrapDestinations_Port]

Defines the port number of the remote SNMP trap manager. The device sends SNMP traps to this port.

The valid value range is 100 to 4000. The default is 162.

'SNMP Version'

snmp-version

[SNMPTrapDestinations_Version]

Defines the SNMP version of the SNMP trap manager (user).

■ [2] SNMPv2 = (Default) Defines the trap manager as an SNMPv2 user.
■ [3] SNMPv3 = Defines the trap manager as an SNMPv3 user. Select the user in the 'SNMPv3 User' parameter (below).

 

'SNMPv3 User'

snmpv3-user

[SNMPTrapDestinations_User]

Assigns an SNMPv3 user from the SNMPv3 Users table (see Configuring SNMPv3 Users) to this SNMP trap destination.

By default, no user is assigned.

Note: The parameter is applicable only if you configured the 'SNMP Version' parameter (above) to SNMPv3.

'Enable'

enable

[SNMPTrapDestinations_Enable]

Enables the SNMP trap manager to receive traps.

■ [0] Disable
■ [1] Enable (default)
