SNMP Management Configuration
SNMP Management Configuration is used to configure the DES-5200 for SNMP
management. Leave the default values in place if you are not managing your
network through SNMP.
The DES-5200 uses the standard MIB-II Management Information Base module.
The MIB values can be retrieved from any SNMP based network manager. The
DES-5200 supports its own proprietary enterprise as an extended MIB. The MIB
can be retrieved by specifying their Object-Identity (OID). MIB values can be
either read-only or read-write.
Read-only MIB variables can be constants that are programmed into the DES-
5200 or variables that change while the DES-5200 is running. For example, the
number and type of ports on the DES-5200 is a read-only constant. The number
and type of ports is fixed. Statistics, such as the number of errors that have
occurred, are read-only variables.
Read-write MIBs are usually related to user customized configurations. Examples
of these are the DES-5200’s IP address, STA parameters and port status.
If you use third party vendors’ SNMP software to manage the DES-5200, a
diskette listing the DES-5200’s proprietary enterprise MIB can be obtained by
request. If your software provides functions to browse or modify MIB, you can
get the MIB values and change them (if the MIB’s attributes permit the write
option). This process can be difficult. You must know the MIB OID’s and retrieve
them individually.
