Description
Logical Port Scaling Class. Indicates which of the four Scaling Class Tables
(see
Table
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.
Shows whether packet discard is enabled or disabled for the service type.
