QoS for IPv6 traffic

QoS for IPv6 traffic
Configuring QoS for IPv6 traffic is generally the same as it is for IPv4 traffic. The QoS policies you
configure on the Brocade device apply to both incoming IPv6 and IPv4 traffic. ACLs can be used to
perform QoS for IPv6 traffic:
• dscp
• fragments
• priority-force
• priority-mapping
• source routing
To enable QoS for IPv6 traffic, enter the following commands.
BigIron RX(config)# port-priority
BigIron RX(config)# write memory
BigIron RX(config)# end
BigIron RX# reload
Syntax: [no] port-priority
NOTE
You must save the configuration and reload the software to place the change into effect. This
applies 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 RX
routers, when QoS is enabled with the port-priority command, the device inserts a value in the
internal 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) header
Clearing global IPv6 information
You 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 flows
Clearing the IPv6 cache
You can remove all entries from the IPv6 cache or specify an entry based on the following:
• IPv6 prefix.
• IPv6 address.
