7.1.2
Supported SNMP Features
The PROFINET Controller supports:
•
SNMPv1 and SNMPv2c
•
MIB-II (see RFC 1213 for details)
•
LLDP MIB (see IEEE 802.1AB for details)
•
LLDP 802.3 Extension MIB (see IEEE 802.1AB for details)
The PROFINET Controller does not:
•
Support SNMPv3.
•
Provide asynchronous notifications via SNMP.

Generate SNMP TRAP or INFORM messages.
7.1.3
SNMP Read Access
SNMP provides standard commands that allow a client to read SNMP data. The PROFINET Controller supports
these commands:
GET
GETNEXT
GETBULK
The SNMP Community strings supported for read access are:
•
public
18
•
pub
•
icmp
•
private
•
priv
•
ge_pnc
19
These community strings are fixed and cannot be changed.
7.1.4
SNMP Write Access
SNMP should not be used to change parameters on the PROFINET Controller module.
•
For PNC001 firmware version 2.05 and earlier, the SNMP SET command succeeds for the variables in some
MIBs/groups, but fails for the variables in other MIBs/groups. Changes made using SNMP SET change only
the SNMP variable itself, do not affect the PNC001 module operation, and are not saved across a power-
cycle or restart. For example, setting the
sysName
variable from the System Group does not change the
Device Name
of the PNC001 module.
•
The SNMP Set command for PNC001 firmware version 2.10 and later is disabled.
18
Requires
PNC firmware version 2.05 or later.
19
Requires
PNC firmware version 2.10 or later.
