Setting the Autopartition Threshold Value
To set the maximum number of data collisions an installed management
module allows on a port before it partitions the port, use the following
management command:
SET MODULE {slot} AUTOPARTITION_THRESHOLD {31_coll}
{63_coll}
{127_coll}
{255_coll}
You can set the autopartition threshold value to one of the following:
31
63 (default value)
127
255
The proper setting for most network environments is 63 (the default). The
10BASE-T specification suggests a minimum autopartition threshold value
of 31, but 31 collisions may cause ports to partition more frequently than
necessary.
Note: Autopartition values 127 and 255 are suggested only for
debugging purposes, and are not recommended for use in
live networks.
