xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual
The xStack DES-3800 Series supports 802.1p priority queuing. The Switch has 8 priority queues. These priority queues are numbered
from 7 (Class 7) — the highest priority queue — to 0 (Class 0) — the lowest priority queue. The eight priority tags specified in IEEE
802.1p (p0 to p7) are mapped to the Switch's priority queues as follows:
•
Priority 0 is assigned to the Switch's Q2 queue.
•
Priority 1 is assigned to the Switch's Q0 queue.
•
Priority 2 is assigned to the Switch's Q1 queue.
•
Priority 3 is assigned to the Switch's Q3 queue.
•
Priority 4 is assigned to the Switch's Q4 queue.
•
Priority 5 is assigned to the Switch's Q5 queue.
•
Priority 6 is assigned to the Switch's Q6 queue.
•
Priority 7 is assigned to the Switch's Q7 queue.
Priority scheduling is implemented by the priority queues stated above. The Switch will empty the eight hardware priority queues in
order, beginning with the highest priority queue, 7, to the lowest priority queue, 0. Each hardware queue will transmit all of the
packets in its buffer before permitting the next lower priority to transmit its packets. When the lowest hardware priority queue has
finished transmitting all of its packets, the highest hardware priority queue will begin transmitting any packets it may have received.
The commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.
