SNMP Configuration
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 Meru Meru 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 loca-
tion.
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 > SNMP > Setup > Download MIB Files > Download MIBs.
When the download is done, you will see the file listed in the Downloads list.
3. Save the file mibs(x).tar.gz.
SNMP Configuration
The SNMP agent in the controller must be properly configured for the following:
1. The read and write community strings must be configured before the Web UI can
be used to view and update any of the components of the controller.
2. The trap manager must be configured so that traps are sent to the correct SNMP
manager.
3. The contact and location information should also be correctly configured so that
the SNMP manager can access this information and know who to contact in case
of problems.
SNMP Community Strings
SNMP community strings authenticate access to MIB objects. They determine whether
the SNMP manager has read and/or write access to particular MIB objects, if at all.
Before the SNMP manager can access a controller, it must supply a community string
that matches at least one of the community string definitions of the controller, with
the same access privileges.
A community string can have one of these attributes:
