Table 1-83 Configurable Flow Control Parameters by Flow-control Type

Flow Control Parameter
-max_priority_class_X
-priority_class <No.>
-discard_class <No.>
-replace_tos <New_Tos Value>
-tos_map
-upc {no | <Bandwidth>}
-upc_penalty drop
-upc_penalty
-modified_priority_class <No.>
-modified_discard_class <No.>
-upc_penalty
<Modified_New_Tos Value>
-replace_exp <Value>
††: required, †: configurable,
1: no (or default value)
2: requires a numeric value
Flow control may be classified into three types by transmission priority:
Condition 1: Precedence not determined by TOS.
Condition 2: TOS is rewritten; converted TOS determines precedence.
Condition 3: Precedence determined by input IP packet TOS.
Condition 4: Determines the EXP and priority level.
Condition 5: Determines the priority level by EXP.
Flow control is further classified using the following three conditions:
Condition 1: No reserve bandwidth management.
Condition 2: Detected flows that violate bandwidth reservation are discarded.
Condition 3: When a detected flow violates bandwidth reservation, its priority
is lowered.
