TRB246 SNMP

The information in this page is updated in accordance with firmware version TRB2M_R_00.07.10.4.

Summary

Simple Network Management Protocol (SNMP) is a network management protocol used for collecting information and configuring network devices. This page is an overview of the SNMP function in TRB246 devices.

Note: SNMP is additional software that can be installed from the System → Package Manager page.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

SNMP settings

The SNMP settings page is used to configure SNMP accessibility and general SNMP information for your device.

SNMP agent settings

---

Field	Value	Description
Enable SNMP service	off | on; default: off	Run SNMP service on system's startup.
Enable remote access	off | on; default: off	Open port in firewall so that SNMP service may be reached from WAN.
IP type	IPv4 | IPv6 | IPv4v6; default: IPv4	IP type used by SNMP.
Port	integer [0..65535]; default: 161	SNMP service's port.
SNMP v1 Mode	off | on; default: on	Enable/disable SNMP v1 Mode.
SNMP v2c Mode	off | on; default: on	Enable/disable SNMP v2c Mode.
SNMP v3 Mode	off | on; default: off	Enable/disable SNMP v3 Mode.

SNMP System Summary

---

The SNMP System Summary section contains general information about SNMP on this device. You can also download this device's MIB file from this section.

Field	Value	Description
MIB file	-(interactive button)	Downloads the device's MIB file.
System OID	1.3.6.1.4.1.48690	OID or Object Identifier, is an identifier used to name and point to an object in the MIB hierarchy.
Location	string; default: location	Trap named sysLocation.
Contact	string; default: [email protected]	Trap named sysContact.
Name	string; default: name	Trap named sysName.

SNMP v3 users

The SNMP v3 users page is used to create and manage users, who can be authenticated using SNMP v3. To configure an SNMP user, you must first create it:

1. Enter a custom name for the new user in the 'Name' field.
2. Click the 'Add' button.
3. Click the 'Edit' button next to the newly created user.

---

The SNMP user configuration window should look similar to this:

Note: this table has coloring scheme to indicate which fields can be seen with different configuration.

Field	Value	Description
Enable	off | on; default: off	Turns this SNMP user on or off.
Username	string; default: none	Set username to access SNMP.
Security level	No authentication, no privacy | Authentication, no privacy | Authentication and privacy; default: No authentication, no privacy	A security level is an authentication strategy that is set up for the user. No authentication, no privacy - authenticates with a username. Authentication - provides MD5 or SHA algorithms for authentication. Privacy - Provides DES or AES encryption.
Authentication, no privacy | Authentication and privacy: Authentication type	SHA | MD5; default: SHA	Set authentication type to use with SNMP v3.
Authentication, no privacy | Authentication and privacy: Authentication passphrase	string; default: none	Set authentication passpharse to generate key for SNMP v3.
Authentication and privacy: Privacy type	DES | AES; default: DES	Set privacy type to use with SNMP v3.
Authentication and privacy: Privacy passphrase	string; default: none	Set privacy passpharse to generate key for SNMP v3.
Access Mode	Read-Only | Read-Write; default: Read-Only	The access mode specifies the access the hosts in the community are allowed with respect to retrieving and modifying the MIB variables from a specific SNMP agent.
MIB subtree	string; default: none	Leave empty to access full MIB tree.

Communities

The SNMP Community section is used to manage access rights. You can edit an SNMP community by clicking the 'Edit' button next to it:

This will redirect you to the community's configuration page.

Field	Value	Description
Community name	string; default: none	Name of the community.
IP Address	ip; default: none	IP address of the community.
IP Mask	ip; default: none	Netmask for IP of the community.

SNMPv6 community configuration page:

Field	Value	Description
Community name	string; default: public	Name of the community.
Source	ip6 | domain name; default: default	Source of the community.
Access Mode	Read-Only | Read-Write; default: Read-Only	Access mode for current community.

Trap Settings

SNMP Traps are used to send alert messages to a central collector, the “SNMP manager” when an important event happens. A benefit of using Traps for reporting alarms is that they trigger instantaneously, rather than waiting for a status request from the manager.

Trap settings page is divided in two sections - Trap service settings and Trap rules. Trap service settings lets you manage hosts which will get configured alert messages, Trap rules lets you manage rules which when triggered will send alerts.

Trap Service Settings

---

The Trap Service Settings is used to manage hosts which will be alerted when an SNMP trap is triggered. The host list is empty by default thus, to begin configuration you must first create at least one host.

Click the 'Add' button at the bottom-right side of the table to create a new host.

The newly added Host configuration should look similar to this:

Field	Value	Description
Host/IP	url | ip; default: none	Hostname or IP address to transfer SNMP traffic to.
Port	integer [0..65535]; default: 162	Trap host's port number.
Community	string; default: Public	Name of the community to which the trap belongs.
Delete	- (interactive button)	Deletes the host next to the button.
off/on slider	off | on; default: off	Turns the host on or off. SNMP traffic is only sent to enabled hosts.

Trap Rules

---

SNMP Trap Rules are alerts that trigger when certain user-specified events occur. When the trigger event happens, the trap will notify known SNMP hosts.

You can create a new trap rule by clicking the 'Add' button.

You should be redirected to the rule's configuration page which should look something like this:

Above is an example of what rule configuration window looks like. Below is a table with detailed explanations on how to configure the rule and what each of the fields mean.

To avoid redundancy, screenshots for the other rules will not be provided, since the structures, syntax and the overall look of the configuration windows for each rule are very similar. Instead, only tables containing information on how to edit each rule will be provided.

Signal strength

---

Field	Value	Description
Enable	off | on; default: off	Enable or disable this rule.
Action	Signal strength trap	Rule will be triggered if signal strength falls below specified number.
Signal strength	integer [-130..0]; default: none	GSM signal's strength value in dBm, e.g. -85

Connection type

---

Field	Value	Description
Enable	off | on; default: off	Enable or disable this rule.
Action	Connection type trap	Rule will be triggered when connection type will change.

Input/Output

---

field name	value1	description
Enable	off | on; default: off	Enable or disable this rule.
Action	Input/Output trap	Rule will be triggered when specified input or output state will change.
Input/Output type	Input/Output | ADC; default: Input/Output	Which type of Inputs and Outputs to use in this rule.
