CobraNet Programmer’s Reference
Management Interface Variable Reference
Name ifMtu
Description
The size of the largest datagram or ‘packet’ that can be sent/received by the interface, specified in
octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest
network datagram that can be sent on the interface.
Host Address
0x11000B
SNMP Object ID
1.3.6.1.2.1.2.2.1.4
Type
Integer
Attributes
Read-only
Default Value 1500
Implemented Version 2.1.0
Name
ifSpeed
Description
An estimate of the interface's current bandwidth in bits per second or Mbits per second (see Notes
below). For interfaces which do not vary in bandwidth or for those where no accurate estimation can
be made, this object should contain the nominal bandwidth.
Host Address
0x11000C
SNMP Object ID 1.3.6.1.2.1.2.2.1.5
Type Gauge32
Attributes
Read-only
Default Value
100
Implemented Version
2.1.0, corrected is 2.6.5 (see Notes below)
Notes
Prior to CobraNet firmware version 2.6.5, ifSpeed was incorrectly reported via SNNP in Mbit/second
units (100Mbit interface ifSpeed reported as “100”). 2.6.5 correctly reports ifSpeed in bits per
second units via SNMP but due to space constraints, ifSpeed is still reported in Mbit per second
units via HMI on 24-bit platforms. ifSpeed is reported consistently in bits per second units on 32-bit
platforms.
Name
ifPhysAddress
Description
The interface's address at the protocol layer immediately `below' the network layer in the protocol
stack.
