9 SNMP

9.1 General

The SNMP version

V2c

or

V3

for

Get

,

Put

and

Notification

(Trap) is used.

A full SNMP agent is implemented on the DTS (MIB II, DTS4138).

For SNMP V2c, following standard

Communities

are used:

Read only :

romobatime

Read/Write:

rwmobatime

Trap:

trapmobatime

For SNMP V3, following standard

User I Passwords

are used:

dtsUser1

mobatime

dtsUser2

mobatime

dtsInfo

mobatime

(not changeable, read only)

DtsUser1 and dtsUser2 have full read/write access on all objects. With SNMP V3 rules,
access can be reduced. Changes of the rules can only be modified over the DTS menu
but not via SNMP.

SNMP V3 agent supports user validation (authentication MD5) and encoding
(encryption DES).

MIB II values like sysDescr, sysContact, sysName, or sysLocation can only be modified
over the DTS menu but not via SNMP.

The following MIB definitions are used:

SNMPv2-SMI, SNMPv2-MIB, SNMPv2-CONF, SNMPv2-TC, SNMPv2-TM,
SNMP-FRAMEWORK-MIB, SNMP-MPD-MIB, SNMP-NOTIFICATION-MIB,
SNMP-TARGET-MIB, SNMP-USER-BASED-SM-MIB, SNMP-VIEW-BASED-ACM-MIB,
RFC1213-MIB, IF-MIB, IP-MIB, IP-FORWARD-MIB, TCP-MIB, UDP-MIB,
HOST-RESOURCES-MIB, HOST-RESOURCES-TYPES, DISMAN-EVENT-MIB,
NOTIFICATION-LOG-MIB, UCD-SNMP-MIB, NET-SNMP-MIB, NET-SNMP-TC

SNMP V2c, V3:
DTS-COMMON

(File: DTS-COMMON-MIB.TXT)

General DTS definition, always required
DTS4138 (DTS4138-MIB.TXT)

Device-specific DTS definitions

The MIB files can be copied from the DTS 4138 with FTP (For FTP use, see chapter
“7.6 FTP connection“):

DTS-MIB:

/etc/snmp/mibs/

Standard MIBS:

/usr/share/snmp/mibs/
