SNMP MIB BROWSER CONFIGURATION
The following steps are required to configure Network Manager
MIB variable access through the ESU 120e:
1. Load the desired product MIBs on the network management
station. If, for example, the administrator is managing ESU
120e and ISU 512 devices, load ESU 120e.MIB, ISU512.MIB, and
RFC1406.MIB.
2. Create device entries in the NMS database for all units that are
to be managed through the ESU 120e. The host unit should be
configured as the Proxy agent for the external units. The IP
address or host name used for the proxy designation is that of
the ESU 120e.
3. Set community names in the device’s entries for external units
to the ESU 120e community name with the device Unit ID
appended as defined in the previous section ESU 120e SNMP
ACCESS.
4. Set the device timeout for all device entries in the NMS device
database to five seconds, including the host unit.
SNMP MIB FILES
The ESU 120e supports several standard MIBs including MIB-II
(RFC-1213), the DS1 E1/E1 MIB (RFC-1406), and the Ethernet MIB
(RFC-1643). It also supports several ADTRAN enterprise-specific
MIBs including the ADTRAN Product MIB (ADTRAN.MIB), the
ADTRAN DS1 extensions MIB (ADS1.MIB), and all ESU/TDU
Enterprise MIBs, such as ESU 120e.MIB.
The standard MIB files are usually included with most SNMP net-
work management software. The latest version of the ADTRAN
enterprise specific MIBs are available from the ADTRAN anony-
mous ftp site (ftp.adtran.com), or by dial-up from the BBS (205 -
971-8169). The MIB files are also located on the ADTRAN WWW
site at http://www.adtran.com.
