• Ring performance is eroding as a result of this problem

Exceeding the threshold causes REM to notify the IBM LAN Network Manager

of the error/ring-performance condition. The notification appears as a Weight

Threshold event that you can view and interpret with the Bay Networks Events

Manager tool.

After you determine the typical (noncritical or tolerable) error characteristics of

the local ring, you can set a value for the Error Rate Threshold, which is an LNM

interface parameter. The threshold you set provides for adequate warning of

legitimate (performance-degrading) problems on the locally attached ring. (Until

you make this determination, you can use the default Error Rate Threshold setting

provided by the Bay Networks LNM Servers software.)

For information about how to access and edit the Error Rate Threshold parameter,

refer to Chapter 4.

Intensive Mode Reporting Function

The REM Intensive Mode Reporting Function is a facility that enables an IBM

LAN Network Manager to request a Ring Error Monitor to forward selected

soft-error MAC frames. The requesting IBM LAN Network Manager receives the

requested frames.

Receiver-Congestion Error Reporting Function

The REM Receiver-Congestion Error Reporting Function identifies stations that

cannot receive a significant number of frames from the ring because their input

buffers are full.

Status Request Function

The REM Status Request Function accepts and responds to requests for status

from IBM LAN Network Manager.

Set Parameters Function

The REM Set Parameters Function accepts and executes requests from the

controlling IBM LAN Network Manager to set REM parameters.
