154CHAPTER 5: OUT-OF-BAND MANAGEMENT

Field

Description

 

 

lateCollisions

Number of times that a collision was detected on this port

 

later than 512 bit-times into the transmission of a frame

lengthErrs

Number of frames received by this port that are longer

 

than 1518 bytes or shorter than 64 bytes

linkStatus

Boolean value indicating the current state of the physical

 

link status for this port (either enabled or disabled)

macAddress

MAC address of this port

multiCollisions

Number of times that multiple collisions were detected on

 

this port.

noRxBuffers

Number of frames that were discarded because no buffer

 

space was available

portLabel

User-defined label name. The maximum length of the

 

string is 32 characters, including the null terminator.

portState

Current software operational state of this port. Possible

 

values are on-line and off-line.

portType

Specific description of this port’s type. Values for each

 

port type: 10/100BASE-TX (RJ-45),100BASE-FX

 

(SC), 1000BASE-SX (SC), 1000BASE-LX (SC).

reqFlowControl

If autonegotiation is disabled, a configurable parameter

 

that sets the flow control option on the port. If

 

autonegotiation is enabled, flow control values are

 

ignored.

reqPortMode

If autonegotiation is disabled, a configurable parameter

 

that sets the port mode on Ethernet ports that have port

 

mode options. If autonegotiation is enabled, port mode

 

values are ignored.

requestedState

Configurable parameter that enables or disables this port.

 

The default is enabled.

rxByteRate

Average number of bytes received per second by this port

 

during the most recent sampling period

rxBytes

Number of bytes received by this port, including framing

 

characters

rxDiscards

Number of received frames that were discarded because

 

there was no higher layer to receive them or because the

 

port was disabled

rxErrs

Sum of all receive errors that are associated with this port

 

(summary report only)

rxFrameRate

Average number of frames that were received per second

 

by this port during the most recent sampling period.

 

Sampling periods are 1 second long and not configurable.

rxFrames

Number of frames that were copied into receive buffers

 

by this port
