Configuring Traffic Filters and Protocol Prioritization
2-20
Parameter: Max High Queue Latency
Default: 250 milliseconds (ms)
Range: 100 to 5000 ms
Function: Specifies the greatest delay that a high-priority packet can experience and,
consequently, how many normal-priority or low-priority bits can be in the
transmit queue at any one time.
For more information about using latency to tune strict dequeuing
protocol prioritization in your network, refer to “Latency,” earlier in this
chapter.
Instructions: Accept the default latency of 250 ms, or enter a new latency value. We
recommend accepting the default latency value of 250 ms.
MIB Object ID: 1.3.6.1.4.1.18.3.5.1.4.1.1.8
Parameter: High Water Packets Clear
Default: 0
Options: Any integer value
Function: Toggles the High Water Packets Clear bit. When you change queue depth
(by changing the value of the High Queue Size, Normal Queue Size, or
Low Queue Size parameter) you can also reset the high water mark by
changing the value of this parameter. When you change the value of this
parameter, you reset the high water mark for all three queues to zero.
For more information about using queue depths to tune protocol
prioritization in your network, refer to “Tuning Protocol Prioritization,”
earlier in this chapter.
Instructions: Enter any new integer value for this parameter to clear the existing high
water marks for the priority queues.
