How do I open the Enterprise web client?

Start the Enterprise server and open the web console address, usually http://127.0.0.1:11900 on the server machine.

How do I manage SNMPv3 USM and VACM from the web client?

Select an SNMPv3 agent in Browser, then open Tools > Manage SNMPv3 USM & VACM. The tool loads USM users and, when available, VACM groups, access rows, and view subtrees.

What does trap rule suppression do?

Suppression delays external trap rule actions for a configured window. The pending actions can be cancelled when the original trap is acknowledged or cleared, when a related trap matches configured conditions, or when an optional ping condition is met.

iReasoning MIB Browser Enterprise Web Client User Guide

First run

Quick start with an SNMP agent

Open the Enterprise web console on the server machine, normally at http://127.0.0.1:11900. A fresh server without an administrator password opens directly. If password protection is configured, sign in as admin.

Enter the agent address. In Browser, type an IP address or host name, such as 192.168.1.10 or 192.168.1.10:161, into the Agent field. On the first run there may be no recent agent items yet; the web client creates or reuses the matching profile when you run the query.

Screenshot of the Browser workspace showing where to enter an SNMP agent IP address or host name — First-time use: type the target SNMP agent address directly into the Agent field.

Confirm SNMPv3 credentials. Click Advanced if the agent profile needs a user name, authentication protocol, privacy protocol, context name, or write credentials. SNMPv3 passwords are write-only and are never returned to the browser.

Screenshot showing a selected SNMPv3 agent with user admin, authentication SHA, privacy AES, and USM/VACM rows — Confirm that the target SNMPv3 profile uses the expected user, authentication, and privacy settings.

Run your first query. Select system or sysUpTime.0 in the MIB tree, choose GET, and click Run. Results appear in the Results tab.

Screenshot of the Browser workspace with MIB tree, OID field, GET operation, Run button, and results table — Choose a MIB node, run GET, and verify returned values in the Results tab.

Try a table and graph. Select an interface table node for Table, or a numeric scalar or instance for Graph. Use this to verify that the web client can reach the target agent.

Screenshot showing Results, ifTable, and Graph tabs with exported query rows from an SNMP agent — Use Table and Graph result tabs after confirming the basic target-agent query works.

Local-only mode: New installations may accept web and Java clients only from the same machine. Use Settings > Security to set a password, allow specific remote IP addresses, or keep the deployment local.

Navigation

Understand the web client interface

The web client is organized around persistent top-level workspaces. Most operations are server-side, so closing a browser tab does not stop the Enterprise server, trap receiver, or saved watch service.

Browser

SNMP operations, MIB tree navigation, results, tables, graphs, bookmarks, and expressions.

Traps

Live notifications, persisted history, severity, acknowledgement, clearing, and rule creation.

Watches

Current monitored values, retained history, alarm state, and watch settings.

Polls

Reusable multi-agent query definitions and run results.

Tools

Discovery, diagnostics, SNMPv3 USM/VACM, NET-SNMP extend, port views, and snapshots.

Settings

Security, agent profiles, MIB files, trap receiver, SMTP, rules, and server status.

Shared state and sessions

Agent profiles, MIB activation, trap receiver settings, rules, watches, polls, and expressions are shared through the Enterprise server. Bookmarks are saved in the current browser and run against the agent currently selected in Browser.

Screenshot overview of the Enterprise web console primary navigation and workspace cards — The top navigation separates live SNMP work, traps, monitoring, reusable polls, tools, and administration.

SNMP operations

Browse MIBs and query agents

The Browser workspace combines an agent selector, MIB tree, OID input, operation selector, result tabs, table views, graphs, and action dialogs.

Operation	Use it for	Notes
GET	Read a scalar or exact instance such as `sysDescr.0`.	Best for known OIDs and quick checks.
GET NEXT	Read the next lexicographic OID after the current value.	Useful when walking manually through a subtree.
GET SUBTREE / WALK	Read every variable below a selected node.	Long runs stream rows into the result tab and can be cancelled.
SET	Write a value to an agent object.	Requires write credentials or SNMPv3 write access through VACM.
Table	Render a MIB table, entry, or table column as a structured grid.	Table cells can be refreshed, graphed, watched, or set when writable.
Graph	Plot a numeric scalar, instance, or table column over time.	Counter-style values can be monitored visually without leaving Browser.

Agent field and Advanced Properties

Enter a host, host:port, IPv6 address, or IPv6 with @port. If the target is not already saved, the web client creates an agent profile using the current default values. Use Advanced to edit SNMP version, communities, SNMPv3 user name, authentication and privacy protocols, context name, and whether localized keys are derived with the engine ID.

MIB tree actions

Search loaded MIB modules by object name or numeric OID.
Select a node to update the OID field.
Use the node details to understand type, access, status, module, and description.
Export a subtree when you need a compact text view of loaded MIB content.

Bookmarks and expressions

Bookmarks save a local shortcut to an OID and operation. Expressions combine one or more OIDs into a calculated value, such as interface throughput. Expression variables can use raw values or counter deltas collected over a short interval.

Screenshot of the Browser workspace with the Tools menu open — The Browser workspace stays active while menus expose saved shortcuts, expressions, management tools, and diagnostics.

MIB management

Load, stage, activate, and unload MIB files

Open Settings > MIB Files to upload modules. Uploads are staged first. Click Activate staged files to reload the complete active MIB set. Existing queries continue, while new translations use the activated files.

Staging protects the active tree

New files remain staged until the chosen set parses successfully. This keeps malformed or incomplete uploads from replacing the currently active MIB tree.

Browser upload shortcut

The Browser workspace can also load MIB files directly. Uploaded modules are activated with the active set so the tree refreshes after parsing completes.

Screenshot of the MIB Files settings page with active and staged MIB modules — MIB uploads are staged before activation, so the active tree is not replaced until parsing succeeds.

Output

Work with results, tables, and graphs

SNMP rows stream into tabs. The main Results tab can keep multiple query batches, while Table, Graph, Poll, and Expression runs open purpose-specific tabs.

Results tab

CSV / JSON

Graph tab

Polling

Use Find in the result table to search names, OIDs, types, values, and agents.
Export completed query results as CSV or JSON.
Cancel a running query from its active tab when a walk or table is no longer needed.
Clear visible rows without deleting server-side saved definitions.

Screenshot of Browser result tabs with query results and CSV JSON export controls — Result tabs group query output, table views, graph views, search, cancellation, and export actions.

Notifications

Receive, review, and classify traps

The Traps workspace shows live notifications and persisted history after filtering and rule evaluation. Use the receiver controls to start, stop, or restart the server-side Trap Receiver.

Trap list

Review source address, OID, severity, received time, acknowledgement state, and parsed variable bindings. Select a trap to inspect details.

Actions

Acknowledge, unacknowledge, clear, or create a rule from the selected trap. When a trap is selected, rule creation pre-fills matching condition fields.

Trap filter

Open Settings > Trap Receiver > Trap Filter to discard matching traps before they appear in the live receiver or trigger rules and actions. Filter by source IP address and trap OID.

Trap sender

The web client includes a Trap Sender for SNMPv1, SNMPv2c, and SNMPv3 traps and informs. Add variable bindings, apply OID suffixes, configure SNMPv3 sender settings, and save sender bookmarks for repeat tests.

Screenshot of the Traps workspace with live trap rows and acknowledgement actions — The Traps workspace shows receiver state, incoming traps, details, acknowledgement controls, and rule creation.

Monitoring

Create Watches and Polls

Watches

Watches collect current values through the Enterprise watch service. Add a watch from a selected Browser OID, review current state, open retained history, and configure the default interval and data retention in Watch Settings.

Polls

Polls are reusable definitions that query selected variables across one or more saved agents. Create or edit a poll, run it on demand, and inspect results in a dedicated tab.

Watches are best for continuous monitoring and historical charts. Polls are best for repeatable inventory, comparison, or troubleshooting queries.

Screenshot of the Watches workspace with current values and a history chart — Watches are continuous server-side measurements with current state and retained history.

Screenshot of the Polls workspace with reusable poll definitions and poll results — Polls are reusable query sets that can run across one or more saved agents.

Diagnostics and device tools

Use the Tools menu

The Tools menu groups discovery, SNMP management, port analysis, device summaries, and network diagnostics.

Tool	Purpose	Typical workflow
Network Discovery	Find reachable IPv4 devices and query SNMP system identity.	Select a saved credential template, enter start and end IPv4 addresses, then discover.
Manage SNMPv3 USM & VACM	Manage remote SNMPv3 users and access-control policy.	Select an SNMPv3 agent in Browser, then open the tool.
Manage NET-SNMP extend	Create, inspect, and remove NET-SNMP extend rows.	Use only with agents that expose the NET-SNMP-EXTEND-MIB tables.
Port View	Monitor IF-MIB interface utilization and error rates.	Choose a metric, refresh, or poll every 5 seconds.
Switch Port View	Correlate IF-MIB interfaces with bridge forwarding database entries.	Use with switches that expose bridge forwarding information.
Device Snapshot	Summarize system, interface, storage, process, and installed software data.	Run against a saved agent to gather HOST-RESOURCES-MIB and MIB-II data.
Ping	Run an ICMP reachability test from the Enterprise server.	Enter host, count, and timeout.
Trace Route	Show the network path from the Enterprise server to a host.	Enter target, maximum hops, and hop timeout; stop if needed.

Network Discovery uses a saved agent profile as the credential template for SNMP identity checks.

New SNMPv3 management tool

Manage SNMPv3 USM & VACM

Open Tools > Manage SNMPv3 USM & VACM after selecting a target SNMPv3 agent in Browser. Confirm its SNMPv3 user, authentication protocol, privacy protocol, and context in Advanced before making changes.

Select SNMPv3 agent Open Tools menu Load USM users Inspect VACM policy

USM user table

The tool queries usmUserTable from SNMP-USER-BASED-SM-MIB. It shows user name, authentication protocol, privacy protocol, storage type, and row status.

Action	What it does	Important detail
Clone	Creates a new USM user from the selected row.	Choose Create and activate or Create and wait.
Activate	Sets the selected user row to active.	The agent must permit the SET through its current SNMPv3 access policy.
Deactivate	Disables the selected user row without deleting it.	Use when rotating users or temporarily blocking access.
Delete	Removes the selected USM user row.	Confirm the deletion. Keep at least one working administrative user.
Refresh	Reloads USM users and VACM information from the selected agent.	Use after any remote change.

VACM access details

When the agent supports SNMP-VIEW-BASED-ACM-MIB, the tool also queries vacmSecurityToGroupTable, vacmAccessTable, and vacmViewTreeFamilyTable. Select a USM user to show its security name, group mapping, access rows, and referenced read, write, and notify view subtrees.

VACM groups

A group maps a USM security name to access policies. You can assign the selected user to an existing group, create a group with its first access-policy row, or delete a group and its mappings.

VACM views

Views define included or excluded subtrees. Create a view subtree by entering a view name, subtree OID, optional hexadecimal mask, and type. Delete removes only the selected subtree row.

Access control matters: USM and VACM management uses SNMP SET operations against the selected agent. The currently selected user must have write access to the relevant USM and VACM MIB rows, or the agent will reject the change.

Partial and unavailable states

Some agents expose USM but not VACM, or expose only part of the VACM tree. In that case the details area explains what could not be loaded while the available USM actions remain usable.

Screenshot of Manage SNMPv3 USM Users and VACM showing users table group mapping and view subtrees — The USM/VACM tool combines user row actions with VACM group, access-policy, and view-subtree inspection.

New trap rule feature

Use Suppression in trap rules

Suppression delays external actions after a rule matches an incoming trap. The delay gives the system a chance to cancel noisy notifications when the original problem is acknowledged, cleared, or followed by a related clearing trap.

Trap matches rule Actions are delayed Clear condition may cancel Actions run or expire

Configure suppression

Open Settings > Trap Receiver > Rules.
Add or edit a rule and define at least one incoming trap condition.
Set severity, description, and optional actions in the Actions tab.
Open the Suppression tab and select Enable action suppression.
Enter Delay actions for as a positive number of minutes.
Optionally add cancellation conditions for a related trap or PING result.
Save the rule.

Cancellation conditions

Condition	How it cancels pending actions
Original trap is acknowledged or cleared	Ack or clear the triggering trap during the delay window. Pending rule actions and delayed system-wide email for that trap are cancelled.
Trap OID	A later related trap cancels the delay when its OID matches the configured OID. Wildcards `*` and `?` are supported.
Trap source IPs	A related trap cancels the delay when its source matches one of the comma separated literal or wildcard source patterns.
Variable-binding values contain	A related trap cancels the delay when any raw variable-binding value contains one of the entered text values. Separate alternatives with commas or vertical bars.
PING	After the delay, the server pings the configured target once. Choose Succeeds to cancel when the host responds, or Fails to cancel when it fails or times out. Use `$ip` for the triggering trap source.

What is delayed

Sound, rule email, command execution, rule SNMP requests, outgoing trap actions, and system-wide SMTP forwarding are held until the delay expires. If no cancellation occurs, each pending action runs once.

Severity and description changes are applied immediately because they describe the received trap. They are not external actions.

Multiple matching rules: Each suppression-enabled rule uses its own delay. System-wide email waits for the longest applicable delay and is cancelled if any applicable rule's cancellation condition is met.

Screenshot of the Trap Rules settings page with delayed and active rules — The Rules page shows conditions, rule result, external actions, and suppression status.

Screenshot of the Add rule dialog with the Suppression tab selected — The Suppression tab configures delay length and cancellation conditions such as related traps and PING.

Administration

Configure the Enterprise server

Settings are shared by web and Java clients unless the page explicitly says a preference is local to the browser.

Settings page	Use it for
Security > Local Machine Only	Restrict web and Java clients to loopback peers or allow permitted remote clients.
Security > Change Password	Set, change, or disable the `admin` password.
Security > Allowed IP Addresses	Allow literal IPv4/IPv6 addresses or inclusive address ranges when local-only mode is off.
General	Change appearance for this browser and defaults shared by clients.
Agent Profiles	Add saved agents and edit default values for new profiles. Credentials are write-only.
Trap Receiver General	Configure ports, bind address, UDP/TCP, persistence, forwarding, allowed communities, and command action support.
SMTP	Forward traps by email using password authentication or OAuth for Gmail and Microsoft Outlook.
Email Template	Edit the plain-text subject and body used for trap email notifications.
SNMPv3 Trap Receiver	Add trusted USM users for authenticating and decrypting incoming SNMPv3 traps.
Rules	Create trap matching rules, actions, ignore behavior, and suppression.

SMTP and OAuth

SMTP can use traditional host, user, and password settings, or OAuth for Gmail and Microsoft Outlook. OAuth setup is available when the web client is opened on the Enterprise server using localhost. Saved OAuth credentials stay on the server.

Screenshot of Trap Receiver General settings with ports transport persistence and forwarding fields — Trap Receiver General controls ports, transport, persistence, forwarding, communities, and command action behavior.

Screenshot of SMTP forwarding settings with primary OAuth and secondary SMTP server sections — SMTP settings support primary and secondary delivery paths, including OAuth-based Gmail or Outlook authorization.

SNMPv3 trap receiver users

Open Settings > Trap Receiver > SNMPv3 Trap Receiver to add users trusted for incoming SNMPv3 traps. When the receiver is running, adding or deleting a user restarts it so the new trusted-user list takes effect.

Screenshot of SNMPv3 Trap Receiver settings showing trusted USM users — Trusted SNMPv3 trap users define who may authenticate or decrypt incoming SNMPv3 notifications.

Screenshot of Server and Security settings showing license receiver and access status cards — Server and Security settings summarize license, receiver state, local access, and administrator policy.

Operational notes

Troubleshooting and safe operation

The page asks for sign-in

Use account admin. If the password was changed, existing sessions and Java clients must sign in again.

The SNMP agent does not respond

Confirm the SNMP agent is running, the selected profile uses the right host and port, and the SNMP version and credentials match the agent.

SET fails

Check write community for SNMPv1/v2c or VACM write view for SNMPv3. Some agents expose rows as read-only or require RowStatus sequencing.

Trap emails do not send

Verify SMTP settings, recipients, OAuth authorization, and whether a suppression-enabled rule is delaying or cancelling system-wide email.

Credential handling: Do not place SNMP communities, authentication passwords, privacy passwords, OAuth secrets, or localized keys in screenshots, tickets, or logs. The web client intentionally treats these values as write-only.
