Item Description
Port Displays the port number of the device.
Maximum SDU Enter the value of the Maximum SDU size parameter for the traffic
class supported by the port (values: unsigned integer in the range 0 to
10240). A value of 0 is interpreted as the Maximum SDU size
supported by the underlying MAC: 10240. The default value of the
Maximum SDU parameter is 1536.
The Maximum SDU size parameter is used to calculate the guard
band time = Maximum SDU * 8 / LINK_SPEED (sec)
If frame preemption is enabled and a gate operaton is SetAndHold,
the guard band time in preemptable queues is automatically selected
as the frame preemption minimum fragment size plus 64 bytes.
A queue is said to be preemptible, if frame preemption is enabled, and
if this queue is not opened in a SetAndHold gate operation.
