15.1.2 What You Need to Know About the Link Aggregation Screens
The following terms and concepts may help as you read through this chapter.
Dynamic Link Aggregation
The ONU adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port trunking.
The ONU supports the link aggregation IEEE802.3ad standard. This standard describes the
Link Aggregate Control Protocol (LACP), which is a protocol that dynamically creates and
manages trunk groups.
When you enable LACP link aggregation on a port, the port can automatically negotiate with
the ports at the remote end of a link to establish trunk groups. LACP also allows port
redundancy, that is, if an operational port fails, then one of the “standby” ports become
operational without user intervention. Please note that:
• You must connect all ports point-to-point to the same Ethernet switch and configure the
ports for LACP trunking.
• LACP only works on full-duplex links.
• All ports in the same trunk group must have the same media type, speed, duplex mode and
flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing
network topology loops.
Link Aggregation ID
LACP aggregation ID consists of the following information (port priority and port number are
0 as it is the aggregator ID for the trunk group, not the individual port):
15.2 Link Aggregation Status
Click Advanced Application > Link Aggregation in the navigation panel. The Link
Aggregation Status screen displays by default. See Section 15.1 on page 115 for more
information.
