CoS Inputs and Outputs Overview
date_range
29-Nov-23
Some CoS components map one set of values to another set of values. Each mapping contains one or more inputs and one or more outputs. When you configure a mapping, you set the outputs for a given set of inputs, as shown in Table 1.
CoS Mappings | Inputs | Outputs | Comments |
|---|---|---|---|
The map sets the forwarding class and packet loss priority (PLP) for a specific set of code points. | |||
The map sets the drop profile for a specific PLP and protocol type. | |||
The map sets the code points for a specific forwarding class and PLP. | |||
(Systems that support native Fibre Channel interfaces only) The map sets the code point for the forwarding class specified in the fixed classifier attached to the native Fibre Channel (NP_Port) interface. |
