Line Configuration Problems
Selective scanning allows a low-speed scanner to run different -line configurations at different times,
such as at night and during the day. However, this flexibility makes it possible for you to create a
condition in which the lines exceed the capacity of the scanner.
If your operational practice is to change among different line configurations, each of which is within the
capacity of the scanner, make sure that you deactivate all lines which do not apply to the configuration
you are changing to.
Problems on Multiple Lines Having Common Parameters.
1
When multiple lines are failing, they may have common parameters such as, direct
attach, line speed, etc, and one of these parameters may be the cause of the
problem.
1. Use the MOSS LID function to display the line parameters.
Refer to the 3745 Advanced Operations Guide.
2. Look at NCP generation to make sure that parameters match the installed
hardware.
3. Check the line weights on the active lines to see -if the capacity of the scanner
is exceeded (sum of line weights greater than 100).
