Range of performance of the CP as an SNMP agent
The CP supports data queries using SNMP in version V1.
For the CP to support the object groups of the standard MIB-II:
● Supported object groups:
System, Interfaces, Address Translation (AT), IP, ICMP, TCP, UDP, SNMP
● Object groups not supported:
EGP, Transmission
Write access is permitted only for the following MIB objects of the "System" group:
● sysContact, sysLocation, sysName
A set sysName is sent as the host name using DHCP option 12 to the DHCP server to
register with a DNS server.
For all other MIB objects and MIB object groups, only read access is possible for security
reasons.
The CP does not support traps.
Access permissions using community name
The CP uses the following community names to control the access rights in the SNMP
agent:
Table 5- 3 Access rights in the SNMP agent
*) Note the use of lowercase letters!
Ethernet interface (X1) > Advanced options
Ethernet interface (X1) > Advanced options > TCP connection monitoring
The setting made here applies globally to all TCP connections of the CP.
With the DNP3 CP, note the option of overwriting the value configured here for individual
communications partners, refer to the section Partner stations (Page 46).
