CLP_LO/EPD1
or
CLPlo/EPD (cells)
or
CLPlo/EPD1 (cells)
0–1000000 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.
Note On AXSM/A and AXSM/B cards, this
parameter is called “CLP_LO /EPD1.”
On AXSM-E cards, this parameter is
called “CLPlo/EPD (cells).” On
AXSM-XG cards, this parameter is called
“CLPlo/EPD1 (cells).”
SCALING COSB
or
SCALING CLASS
1–4 Class of Service Scaling Class. Indicates which
of the four Scaling Class Tables (see Table 4-7,
1–4) 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.
Note On AXSM/A and AXSM/B cards, this
parameter is called “SCALING COSB.”
On AXSM-E and AXSM-XG cards, this
parameter is called “SCALING CLASS.”
SCALING Log-If 1–4 Logical Port Scaling Class. Indicates which of the
four Scaling Class Tables (see Table 4-8, 1–4) 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.
Note This parameter is only available on
AXSM/A and AXSM/B cards.
