• A port that joins a dynamic aggregation group after the Selected port limit has been reached is
placed in Selected state if it is more eligible to be selected than a current member port.
Load sharing criteria for link aggregation groups
In a link aggregation group, traffic may be load-shared across the selected member ports based on a set
of criteria, depending on your configuration.
You can choose one of the following criteria or any combination of the criteria for load sharing:
• Per-flow load sharing—Classifies traffic flows by source or destination MAC address,
source/destination port number, ingress port, source or destination IP address, or MPLS label, or
any combination of them, and forwards packets of the same flow on the same link.
• Packet type-based load sharing—Automatically chooses link-aggregation load sharing criteria
based on packet types (Layer 2, IPv4, MPLS, or IPv6 for example).
