Configuring SNMP

The SNMP Agent offers the network administrator performance management and fault management features, with the collection of statistics as well as notification of unusual events via traps.

This information applies to all controller models and the following AP series:

• AP400
• AP1000

The Wireless LAN System SNMP Agent can inter-operate with 3^rd party Network Management Systems (NMS) such as HP OpenView, and present alarm and trap information to configured management stations.

Fortinet FortiWLC (SD) supports several versions of SNMP protocols. On Fortinet software, all versions (SNMPv1, SNMPv2c, and SNMPv3) of the Internet-Standard Management Framework share the same basic structure and components. Furthermore, all versions of the specifications of the Internet-Standard Management Framework follow the same architecture.

No	Feature	RFCs
1	SNMPv1	RFC-1155, RFC-1157
2	SNMPv2c	RFC-1901, RFC-1905, RFC-1906
3	SNMPv3	RFC-1905, RFC-1906, RFC-2571, RFC-2574, RFC-2575
4	MIB-II	RFC-1213
5	Fortinet Private MIB	Fortinet Wireless LAN Proprietary MIB

Note that Fortinet FortiWLC (SD) doesn’t support write operation through SNMP. You need to provision any required configuration through the CLI or Web UI.

Features

The following protocols are supported for the read function only (not write):

• RFC-1214
• SNMPv1/v2c/v3
• Fortinet WLAN systems

SNMP Architecture

Figure 77: SNMP Network Management Architecture

The Wireless LAN System SNMP network management architecture follows the client-server architecture as illustrated in the diagram. The SNMP model of a managed network consists of the following elements:

• One or more managed nodes. In the illustration, the controller is among the managed nodes in the SNMP-based managed network. The SNMP agent is resident in the managed node. It collects statistics from the access points and combines them before sending them to the SNMP manager via MIB variables. Configuration information set via SNMP is also propagated to the access points by the SNMP agent.
• At least one management station containing management applications.
• Management information in each managed node, that describes the configuration, state, statistics, and that controls the actions of the managed node.
• A management protocol, which the managers and agents use to exchange management messages. In an SNMP managed network, the management protocol is SNMP (Simple Network Management Protocol). This defines the format and meaning of the messages

Features

 

communicated between the managers and agents. Fortinet Wireless LAN System provides support for traps, gets, and MIB walk functions only.

Neither read nor write privilege gives the SNMP manager access to the community strings. The controller can have an unlimited number of read and read/write community strings.

MIB Tables

The MIB tables supported by the Wireless LAN System SNMP implementation can be downloaded from the controller and then copied to an off-box location. The MIB Tables are also available on the Fortinet web site. A summary of the Wireless LAN System MIB Enterprise tables are:

mwstatistics.1 mwGlobalStatistics.1 * mwIf80211StatsTable.1 mwGlobalStatistics.2 * mwIfStatsTable.1 mwIfStatsEntry.1 mwGlobalStatistics.6 * mwStationStatsTable.1 mwStationStatsEntry.1 mwGlobalStatistics.7 * mwApStationStatsTable.1 mwApStationStatsEntry.1 mwGlobalStatistics.8 * mwCacApStatsTable.1 mwCacApStatsEntry.1 mwGlobalStatistics.9 * mwCacBssStatsTable.1 mwCacBssStatsEntry.1 mwStatistics.2 * mwTop10Statistics.1

mwTop10ApStationProblemTable.1 mwTop10ApStationProblemEntry.1 mwTop10Statistics.2 mwTop10ApStationRxtxTable.1 mwTop10ApStationRxtxEntry.1 mwTop10Statistics.3 mwTop10ApProblemTable.1 mwTop10ApProblemEntry.1 mwGlobalStatistics.4 mwTop10ApRxtxTable.1 mwTop10ApRxtxEntry.1 mwStatistics.1 mwPhoneTable.1 mwPhoneEntry.1 mwStatistics.2 mwPhoneCallTable.1 mwPhoneCallEntry.1 mwStatistics.3 mwStatusTable.1 mwStatusEntry.1

Global statistics use 64 bit counters in FortiWLC (SD) 4.0 and later

Download the MIB Tables for Management Applications

If you are using a third-party SNMP-based Network Manager program, you will need to integrate the Fortinet Wireless LAN System proprietary MIB tables that allow the manager program to manage controllers and APs. The MIB tables are available in a compressed (zipped) file that can be copied from the controller to an off-box location.

To download the enterprise MIB Tables, contained in the file mibs.tar.gz, located in the images directory, use the following CLI commands:

controller# cd image controller# copy mibs.tar.gz off‐box_location

To download the enterprise MIB Tables using the Web UI, follow these steps:

1. Open a Web Browser(IE or Firefox), enter the system IP address (example: https:// 172.29.0.133) and then enter a user name and password (factory default user name/ password is admin/admin).
2. Click Configuration > Wired > SNMP > Download MIB Files.
3. When the download is done, you will see the file listed in the Downloads list.
4. Save the file mibs(x).tar.gz.
