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.
17.2.1 Link Aggregation ID
LACP aggregation ID consists of the following information 1 :
Table 39 Link Aggregation ID: Local Switch
SYSTEM
PRIORITY
MAC ADDRESS KEY
PORT
PRIORITY PORT
NUMBER
0000 00-00-00-00-
00-00 0000 00 0000

1. Port Priority and Port Number are 0 as it is the aggregator ID for the trunk group, not the individual port.
