SNMP interface
All managed Factoryline components have an SNMP agent. This agent of an
FL SWITCH SMN manages Management Information Base II (MIB 2) according to RFC
1213, RMON MIB, Bridge MIB, If MIB, Etherlike MIB, Iana-address-family MIB, IANAifType
MIB, SNMPv2 MIB, SNMP-FRAMEWORK MIB, P Bridge MIB, Q Bridge MIB, RSTP MIB,
LLDP MIB, and private SNMP objects from Phoenix Contact (FL-SWITCH-M MIB).
Network management stations, such as a PC with Factory Manager, can read and modify
configuration and diagnostic data from network devices via the Simple Network Manage-
ment Protocol. In addition, any SNMP tools or network management tools can be used to
access Factoryline products via SNMP. To do this, the MIBs supported by the relevant de-
vice must be made available to the SNMP management tools.
On the one hand, these are globally valid MIBs, which are specified and described in RFCs
(Request for Comments). This includes, for example, MIB2 according to RFC1213, which
is supported by all SNMP-compatible network devices. On the other hand, manufacturers
can specify their own SNMP objects, which are then assigned to a private manufacturer
area in the large SNMP object tree. Manufacturers are then responsible for their own private
(enterprise) areas, i.e., they must ensure that only one object is assigned to an object ID (ob-
ject name and parameters) and can be published. If an object is no longer needed, it can be
labeled as “expired”, but it cannot be reused with other parameters under any circum-
stances.
Phoenix Contact provides notification of ASN1 SNMP objects by publishing their descrip-
tions on the Internet.
Reading SNMP objects is not password-protected. However, a password is required for
read access in SNMP, but this is set to “public”, which is usual for network devices, and can-
not be modified. By default upon delivery, the password for write access is “private” and can
be changed by the user.
Another benefit for the user is the option of sending traps using the Simple Network Man-
agement Protocol.
Management Information Base (MIB)
Database which contains all the data (objects and variables) required for network manage-
ment.
Agent
An agent is a software tool which collects data from the network device on which it is in-
stalled and transmits this data on request. Agents reside in all managed network compo-
nents and transmit the values of specific settings and parameters to the management sta-
tion. On a request of a manager or on the occurrence of a specific event, the agent transmits
the collected information to the management station.
Traps
Traps are spontaneous SNMP alarm or information messages that are sent by an SNMP-
compatible device when specific events occur. Traps are transmitted with maximum priority
to various addresses, if required, and can then be displayed by the management station in
plain text. The IP addresses that are to receive these traps (trap targets/receivers) must be
set by the user on the relevant device.
SNMP, the web interface, and the serial terminal all use the same password, which can
be changed by the user.
