7.1.5 MIB-II Groups Supported
The PROFINET Controller supports all of the mandatory values in the following groups of the MIB-II
specification:
• System group
• Interfaces group
• IP group
• ICMP group
• TCP group
• UDP group
• Transmission group (802.3 Ethernet subset)
• SNMP group
The EGP group and Address Translation group of MIB-II are not supported.
The meanings of the values in these groups are well defined in the standard literature. However, the contents
of some values are implementation-specific. This section explains contents of values specific to the PROFINET
Controller.
7.1.5.1 Interface Number
Many MIB-II groups use an SNMP interface number to refer to a device port. For the PROFINET Controller
module the interface numbers are:
Physical Port
SNMP Interface Number
External Port #1
1
External Port #2
2
External Port #3
3
External Port #4
4
Internal Data Port
5
7.1.5.2 MIB-II Interface Group Values
For the MIB-II Interface Group, the ifDescr value provides a textual description of the corresponding
interface/port. The values returned for that item are the same as the port numbers listed above.
The counters ifInDiscards and ifInUnknownProtocols are always reported as zero.
