QOS Parameters :----
Total Bandwidth consumption for different Traffic on a particular interface can be Capped to a particular limit .e.g Video Traffic has to be capped with 40% of the available bandwidth on an interface. To specify max. percentage of total bandwidth that a forwarding class can use , configure a transmit rate.
transmit-rate percent 40;
This configuration sets the maximum transmission rate for assured forwarding class to 40% of the available bandwidth on interface.If the total throughput of the link is 1.5Mbps
At most this class will consume 600kbps.
This will help in case where High Priority & ...view middle of the document...
Tail drop profiles define the meanings of the loss priorities. When you configure tail drop profiles you are essentially setting the value for queue fullness. The queue fullness represents a percentage of the memory used to store packets in relation to the total amount that has been allocated for that specific queue.
The queue fullness defines the delay-buffer bandwidth, which provides packet buffer space to absorb burst traffic up to the specified duration of delay. Once the specified delay buffer becomes full, packets with specified drop probability are dropped from the tail of the buffer on the basis of the configured value.
Tail Drop Profiles can be set for both Inbound/Outbound traffic :-----
