Monitoring & Diagnostics
The port-specific information of the MIB-2 describes diagnostic data about the network
connections, including the IO-Link ports:
MIB variable
Ethernet port
IO-Link Port
ifIndex
A unique value, contiguously
starting from 1.
ifDescr
A textual string containing
information about the interface,
i.e. "Ethernet X”
”IO-Link X" / “IO-IN X” / ”IO-OUT
X”
ifType
IANAifType = 6
(ethernetCsmaCd) when
Ethernet
IANAifType = 280 (sdci) when
IO-Link-Port
= 0 (other) when I/O-Port
ifMTU
length of Ethernet MTU
length of IO-Link process data
(typically max. 32 Byte) or 1,
when IO-port
ifSpeed
actual Ethernet speed
IO-Link speed (no device = 0
bit/s, Com1 Mode = 4800 bit/s,
Com2 Mode 38400 bit/s, Com3
Mode = 230400 bit/s)
ifPhysAddress
MAC address assigned to this
port
This object may contain an octet
string of zero length, since IO-
Link is a serial P2P protocol
with no specific addressing.
ifAdminStatus
Up(1), Down(2), depending
Up(1), Down(2), depending if
IO-Link capability is configured.
ifOperStatus
Up(1), Down(2), depending if an IO-Link device is connected and
operable.
ifLastChange
The value of sysUpTime at the
time the interface entered its
current operational state. If the
current state was entered prior
to the last re-initialization of the
local network management
subsystem, then this object
contains a zero value.
n/a
ifInOctets
The total number of octets received on the interface, including
framing characters.
ifInErrors
n/a
Number of received frames that
were rejected as invalid by the
IO-Link-Master (Abort).
ifOutOctets
The total number of octets transmitted out of the interface,
including framing characters.
ifOutErrors
n/a
Number of retries by the IO-
Link-Master, indicating
unsuccessful packet
transmissions.
