Queue groups may be created on egress network ports to provide network IP interface queue redirection. A single set of egress port-based forwarding class queues are available by default and all IP interfaces on the port share the queues. Creating a network queue group allows one or more IP interfaces to selectively redirect forwarding classes to the group to override the default behavior. Using network egress queue groups, it is possible to provide dedicated queues for each IP interface.
Non-IPv4/non-IPv6/non-MPLS packets remain on the regular network port queues. Therefore, when using an egress port-scheduler, it is important to parent the related regular network port queues to appropriate port-scheduler priority levels to ensure the needed operation under port congestion. This is particularly important for protocol traffic such as LACP, EFM-OAM, ETH-CFM, ARP, and IS-IS, which by default use the FC NC regular network port queue.
