Operating Manual
Committed information rate -> ingress rate limit [in bps],
[1..100M, OFF]. Use the RATELIMIT OFF to turn off
rate limiting for this port.
Committed burst size -> buffer depth reserved for
bursts [in bytes],
If the port has flow control enabled (i.e. PAUSE in full duplex mode or jamming in
half duplex mode), flow control shall be triggered if the buffer is over the limit. In
other modes the frames simply get discarded.
Due to the embedded memory size of 64 KB, the CBS is limited to ~32 KB.
Larger values may be configured, but have no effect on Ethernet performance.
SCHEDULING Policy
Determines the scheduling policy.
STRICT Strict priority scheduling. Higher priority
queues are emptied before any lower
priority queue is processed. Note that
strict priority scheduling can lead to
starving of lower priority queues. Starv-
ing can be avoided either by rate limit-
ing or by using WFQ scheduling.
WFQ Weighted fair queuing. Queues are
emptied with weights 8:4:2:1 applied to
the priorities.
