Mapping IPv6 Traffic Classes
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.)
Command Usage
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.
Command Attributes
Port – Port identifier. (Range: 1-18)
IPv6 Traffic Class – IPv6 traffic class. (Range: 0-255)
Priority – Class-of-Service value (Range: 0-7)
Web – Click Priority, IPv6 Mapping. Select a port for which to set the IPv6
traffic class to CoS map, select the IPv6 traffic class and corresponding
CoS value, then click Add.
