Queuing
This column lists the queuing type, either bandwidth or priority. Class Based
Weighted Fair Queuing (CBWFQ) defines two types of Low Latency Queuing
methods—bandwidth and priority.
• Priority—Priority ensures a fixed amount of bandwidth for whatever
bandwidth value is configured for the QoS class
• Bandwidth—Bandwidth queuing promises a minimum amount of bandwidth.
The traffic may at time receive more bandwidth, but the bandwidth never
drops below the minimum.
Percent

empty if Bandwidth queuing is used.
Remaining Percent
If Bandwidth queuing is used, there is a percent value in this column. This column
is empty if Priority queuing is used.
