Configuring SNMP Trap Destinations

The SNMP Trap Destinations table lets you configure up to five SNMP Trap Managers for receiving traps sent by the device. Trap Managers are defined by IP address or FQDN (IPv4 and/or IPv6).

You can associate a trap destination with SNMPv2 users or a specific SNMPv3 users. Associating a trap destination with an SNMPv3 user 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 the SNMP Trap Manager according to the table below.
4. Click Apply.

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 where the device sends the traps.

The valid value can be 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 traps to the DNS-resolved IP address.

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

Note:

■ Depending on IP version (IPv4 or IPv6), the device uses the corresponding IP Interface (in the IP Interfaces table), assigned in Configuring SNMP Interfaces.
■ If you configure the address as an FQDN:
✔ The IP address version (IPv4 or IPv6) of the FQDN and IP Interface (in the IP Interfaces table) must be the same. For assigning IP Interfaces for SNMP, see Configuring SNMP Interfaces.
✔ To resolve the FQDN into an IP address, the device uses the DNS server configured in the IP Interfaces table of the corresponding IP Interface.
✔ If the DNS response contains multiple DNS-resolved IP addresses, the device uses only the first IP address in the list.
■ 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.

Note: If you configure the parameter to SNMPv3, you need to 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)
