TAS
This page lets you view and set current TAS (Time-Aware Shaper) parameters.
Figure 18-2.2: TAS Status Parameters
Parameter descriptions
:
Port
: Port number of the switch.
Oper Gate Enabled
: The Enabled parameter shows whether traffic scheduling is active (true) or inactive (false).
Oper Gate States
: The current state of the gate associated with each Queue (Q0 – Q7) for the Port.
Cycle Time Value
: The operational value of the gating cycle for the Port. The Cycle Time variable is a rational
number of seconds, defined by value and a unit.
Cycle Time Unit
: The operational Cycle Time unit of measure. May be Milliseconds, Microseconds or
Nanoseconds.
Cycle Time Extension
: An integer number of nanoseconds, defining the maximum amount of time by which the
gating cycle for the Port is permitted to be extended when a new cycle configuration is installed.
Base Time
: The operational value of base time, expressed as an IEEE 1588 Precision Time Protocol (PTP)
timescale.
Current Time
: The current time, in
PTPtime
, as maintained by the local system. The value is a representation of
a
PTPtime
value, consisting of a 48-bit integer number of seconds and a 32-bit integer number of nanoseconds.
Only the seconds are displayed.
Config Change Time
: The
PTPtime
at which the next config change is scheduled to occur. The value is a
representation of a PTPtime value, consisting of a 48-bit integer number of seconds and a 32-bit integer number
of nanoseconds.
Config Change Error
: A counter of the number of times that a re-configuration of the traffic schedule has been
requested with the old schedule still running and the requested base time was in the past.
Tick Granularity
: The granularity of the cycle time clock, represented as an unsigned number of tenths of
nanoseconds.
Config Pending
: The value of the
ConfigPending
state machine variable. The value is TRUE if a configuration
change is in progress but has not yet completed.
