When the aggregation state of a local port changes in a dynamic aggregation group, the
aggregation state of the peer port also changes.
•
After the Selected port limit has been reached, a port joining the aggregation group is placed in
the Selected state if it is more eligible than a current Selected port.
Edge aggregate interface
You can configure an edge aggregate interface to connect a network device to a server when the
device and the server are two ends of a dynamic aggregate link. During the server reboot process,
the device cannot receive LACPDUs from the server (the peer system). This feature enables the
aggregation member ports on the device to forward packets from the server during the server reboot
process.
Without this feature, the member ports on the device are placed in the Unselected state, and the
ports discard packets from the server during the server reboot process.
An edge aggregate interface takes effect only when it is configured on an aggregate interface
corresponding to a dynamic aggregation group.
After the server reboot, the device can receive LACPDUs from the server. Then, link aggregation
between the device and the server operates correctly.
Load sharing modes for link aggregation groups
In a link aggregation group, traffic can be load shared across the Selected ports based on any of the
following modes:
•
Per-flow
load
sharing
—Load shares traffic by data flows. The load sharing mode classifies
packets into flows and forwards packets of the same flow on the same link. This mode can be
one or any combination of the following criteria that classify traffic:
{
Source or destination MAC address.
{
Source or destination port number.
{
Ingress port.
{
Source or destination IP address.
{
MPLS label.
•
Packet type-based load sharing
—Load shares traffic automatically based on packet types
(for example, Layer 2 protocol packets, IPv4 packets, MPLS packets, or IPv6 packets).
