BayRS Version 15.5.0.0 Document Change Notice
5-2 314470-15.5 Rev 00
Version 15.2.0.0
The following section corrects erroneous text in the description of the Priority
parameter.
Priority Parameter
The description of the Priority parameter in Appendix A incorrectly states that the
lower the number, the higher the priority. The description should state that the
higher the number, the higher the priority. For example, a server with a priority of
2 will be the active server before a server with a priority of 1.
Version 15.3.0.0
The following section is an amendment to Chapter 2, “Starting Differentiated
Services” in Configuring Differentiated Services.
Implementation Notes
The following guidelines can help you successfully configure DSQMS on your
router:
• You can configure DSQMS on these interfaces only: HSSI, MCT1, MCE1,
T1/FT1, E1/FE1, and synchronous.
• If you enable flow fairness on a queue, you cannot configure that queue as a
best-effort queue. For information about enabling flow fairness on a queue or
designating the queue as best effort, see “Modifying a DSQMS Queue” in
Configuring Differentiated Services.
• If you configure both weighted and priority queues on an interface, you may
experience latency problems with the highest priority queues. To avoid such
problems:
-- Set the DSQMS interface parameter
dequeue-at-line-rate to enabled
(the default value is disabled). See “Configuring DSQMS to Dequeue
Packets at Line Rate” in Configuring Differentiated Services for
instructions.
-- Ensure that the amount of high-priority traffic is not excessive in the
highest priority queues.
