C H A P T E R 3 Standard Configuration

Adaptive Forwarding Mode
Purpose You can:
• Change the Sample Time
• Define the minimum and maximum errors acceptable before
changing the forwarding mode
Note While CRC errors and runts are the most likely parameters
to cause the switching mode to change, they are not the only
ones.
Changing the time to
measure errors
The sample time should be the shortest time needed to detect errors.
If the sample time is too great, there may be too many errors before
the forwarding mode changes. To change the time the switch retains
error counters:
1 Select Device Setup or Stack Setup.
2 Click Switching.
3 Click Advanced.
4 Click Sample Time.
5 Type the required number of seconds.
6 Click OK.
Changing number of
errors before adaptive
forwarding mode operates
Adaptive forwarding changes the forwarding mode depending on the
upper and lower limits of specific error types. To change the number
of upper and lower limits:
1 Select Device Setup or Stack Setup.
2 Click Switching.
3 Click Advanced.
