EFCI 0 to 1000000 Explicit Forward Congestion Indication. The VC
EFCI discard threshold. This value is a
percentage of MAX_CELL THRESH. 1000000 is
equal to 100%.
CLP_HI 0 to 1000000 Cells Loss Priority - High. The high hysteresis
threshold at which CLP (1) cells will be
discarded. The cells will continue to be discarded
until the CLP_LO threshold is reached. This
value is a percentage of MAX_CELL THRESH.
1000000 is equal to 100%.
EPD0 0 to 1000000 Early Packet Discard 0. The maximum threshold
for CLP(0+1) cells. This value is a percentage of
the MAX_CELL THRESH for the connection.
1000000 is equal to 100%.
CLP_LO /EPD1 0 to 1000000 Cells Loss Priority Low / Early Packet Discard 1.
The low hysteresis threshold at which CLP (1)
cells will stop being discarded. If packet mode is
enable, EPD1 executes.
SCALING COSB 1 to 4 Class of Service Scaling Class. Indicates which
of the four Scaling Class Tables (1 to 4, see
Table 7-28) to use for a connection. Each table is
for a specific service category and has an index of
16 entries. Each index entry contains a
percentage by which to scale traffic on a
connection to reduce CoS buffer congestion. The
hardware generates the index and selects the
entries as needed. Each entry is the ratio of the
COSB cell count to the COSB maximum
threshold. CoS scaling occurs when the CoSB
cell count is approximately 50% of the CoSB max
threshold.
SCALING Log-If 1 to 4 Logical Port Scaling Class. Indicates which of the
four Scaling Class Tables (1 to 4, see Table 7-29)
to use on a logical port. Each table is for a specific
service category and has an index of 16 entries.
Each index entry contains a percentage by which
to scale traffic on a connection on a logical port
to reduce congestion. The hardware generates the
index and selects the entries as needed. Each
entry is the ratio of the interface cell count to the
interface maximum threshold. Interface scaling
occurs when the interface cell count is
approximately 50% of the interface max
threshold.
