Example
The following example shows how to map IP DSCP value 1 to CoS value
0:
priority ipv6
This command assigns IPv6 traffic classes to one of the Class-of-Service
values. Use the no form to restore the default setting.
Syntax
priority ipv6 interface traffic-class cos-value
no queue mode
• interface
- unit - Stack unit. (Range: 1)
- port-list - Single port number or list of ports. (Range: 1-18)
• traffic-class - IPv6 traffic class. (Range: 0-255)
• cos-value - Class-of-Service value (Range: 0-7)
Default Setting
No mapping is defined. All traffic classes are placed in the default
priority queue – Queue 2 (the default queue for CoS 0).
Command Mode
Global Configuration
Command Usage
• The Traffic Class field in the IPv6 header may be used by originating
nodes and/or forwarding routers to identify and distinguish between
different classes or priorities for IPv6 packets. (See RFC 2460.)
• Nodes that support a specific use of some or all of the IPv6 traffic
class bits are permitted to change the value of those bits in packets that
they originate, forward, or receive, as required for that specific use.
Nodes should ignore and leave unchanged any bits of the traffic class
field for which they do not support a specific use.
