1084 BigIron RX Series Configuration Guide53-1001986-01QoS for IPv6 traffic43QoS for IPv6 trafficConfiguring QoS for IPv6 traffic is generally the same as it is for IPv4 traffic. The QoS policies youconfigure on the Brocade device apply to both incoming IPv6 and IPv4 traffic. ACLs can be used toperform QoS for IPv6 traffic:• dscp• fragments• priority-force• priority-mapping• source routingTo enable QoS for IPv6 traffic, enter the following commands.BigIron RX(config)# port-priorityBigIron RX(config)# write memoryBigIron RX(config)# endBigIron RX# reloadSyntax: [no] port-priorityNOTEYou must save the configuration and reload the software to place the change into effect. Thisapplies whether you are enabling QoS for IPv6 or IPv4 traffic.The port-priority command globally enables QoS for IPv6 traffic on all interfaces. On the BigIron RXrouters, when QoS is enabled with the port-priority command, the device inserts a value in theinternal Brocade header based on a combination of the following information:• 802.1p priority• Interface priority (if configured)• VLAN priority (if configured)• The DSCP field in the Type of Service (ToS) headerClearing global IPv6 informationYou can clear the following global IPv6 information:• Entries from the IPv6 cache.• Entries from the IPv6 neighbor table.• IPv6 routes from the IPv6 route table.• IPv6 traffic statistics.• IPv6 session flowsClearing the IPv6 cacheYou can remove all entries from the IPv6 cache or specify an entry based on the following:• IPv6 prefix.• IPv6 address.
