Packets can be classified into 16 different FCs when using priority mode queuing.

This feature is available on egress SAPs within any service.

MPLS EXP bits can be changed based on multi-field classification.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, the BA classification can override the forwarding class while the MF classification can override the profile.

The egress port scheduler can have up to 17 children spread across 8 levels.

Multiple egress port schedulers can be assigned to a single port with many HQoS children.

Multiple HQoS policies can be children of a single port scheduler.

The IOM3 adds more memory to both forwarding complexes which increases the total number of queues available.

The IOM3 only contains a single forwarding complex which reduces the number of queues used.

The IOM3 allows multiple forwarding classes to be assigned to a single queue.

The IOM3 allows queues to be dynamically allocated between ingress and egress.

The IOM3 has a larger CPU capable of tracking active hardware queue utilization and adjusting memory allocation accordingly.
