Select one of the options to display one of the five SCT configuration reports. Table 7-31 describes the
reports for each of these options. The following section lists sample reports for each of these options.
Note The option names are case sensitive. For example, the switch does not recognize the vcthr
option. You must enter vcThr.
CLP_HI 0 to 1000000 Cells Loss Priority High. The maximum
number of cells that can be queued in the
buffer. CLP(1) cells that exceed this
threshold are discarded. This threshold is a
percentage of the MAX_CELL THRESH for
the connection. 1000000 is equal to 100%.
EPD0 0 to 1000000 Early Packet Discard 0. The maximum
number of cells that can be queued in the
buffer in packet mode. Any CLP(0+1) cells
that exceed this threshold, will be discarded.
This threshold is a percentage of the
MAX_CELL THRESH for the connection.
1000000 is equal to 100%.
CLP_LO EPD1 0 to 1000000 Cell Loss Priority Low/ Early Packet
Discard 1. The threshold at which CLP(0+1)
cells that exceed this threshold are discarded.
This threshold is a percentage of the
MAX_CELL THRESH for the connection.
1000000 is equal to 100%.
RED 0 to 1000000 Random Early Discard. The threshold at
which the COSB Random Early Discard is
activated. This threshold is a percentage of
the MAX_CELL THRESH for the
connection. 1000000 is equal to 100%.
RED PROB FACTOR 0 to 15 RED Probability Factor. The mantissa value
of probability for maximum discard when
RED is activated. Determined as
1/2^<value>.
