IPv6 QoS

QoS features supported for IPv6 environments include packet classification, queueing, traffic shaping, packet marking, and policing of IPv6 packets. These features are available for all FastIron products. The feature set is identical to that in IPv4.

To implement QoS in networks running IPv6, follow the same steps as those to implement QoS in networks running only IPv4. The recommended steps are as follows:

  • Identify applications in your network and understand the characteristics of the applications so that you can make decisions about what QoS features to apply.
  • Depending on network topology, link-layer header sizes are affected by changes and forwarding.
  • Decide the method of classification, marking, and rate limiting. If the same network is carrying IPv4 and IPv6 traffic, decide if you want to treat both the same or differently, and specify match criteria accordingly. If you want to treat them the same, use match statements such as match dscp and set dscp. If you want to treat them differently, add match criteria such as match protocol ip and match protocol ipv6 in the match criteria.
Note: The command syntax for IPv6 access control lists (ACLs) is different from the syntax for IPv4. See the “IPv6 ACLs” section in the Ruckus FastIron Security Configuration Guide.
