Range of performance of the CP as an SNMP agent
The CP supports data queries in the following SNMP versions:
● SNMPv1 (standard)
● SNMPv3 (Security)
It returns the contents of MIB objects of the standard MIB II according to RFC 1213 and the
Siemens Automation MIB.
●
The CP supports the following groups of MIB objects:
– System
– Interfaces
The "Interfaces" MIB object provides status information about the CP interfaces.
– IP
– ICMP
– TCP
– UDP
– SNMP
The following groups of the MIB II standard are not supported:
– Adress Translation (AT)
– EGP
– Transmission
●
The following exceptions / restrictions apply to the CP.
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 / MIB object groups, only read access is possible for security
reasons.
Traps are not supported by the CP.
For more detailed information about the MIB files and SNMP, refer to the manual /5/
