config cos mapping
Purpose Used to configure class of service parameters and mapping for port-based cost of
service and mapping for Type of Service (ToS).
Syntax
config cos mapping port [<portlist> | all] [none | {port_mapping | ethernet
[802.1p | mac_mapping] | ip [tos | dscp]}]
Description Class of Service is configured to map different QoS priority protocols to the Switch’s 4
internal priority queues. CoS mapping can be used to accommodate packets using
ToS priority or DSCP priority in their headers. CoS can also be based on destination
MAC address. Port-based CoS can be enabled on any port and mapped to one of two
priority queues.
Parameters mapping - Specifies CoS mapping based on port (port <portlist> or all). Port based
CoS may be further configured as follows:
• none – Specifies port-based CoS mapping without additional specification.
• port_mapping - Enables CoS mapping for the specified ports
• ethernet – Specifies port-based CoS mapping on selected ports to be 802.1p
priority mapping or MAC address based mapping mac_mapping.
• mac_mapping – Specifiies CoS mapping based on destination MAC address
(destination_addr <macaddr>). There are four priority levels available for
mapping as defined by the class (class <class_id 0-3>).
