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

:
Algorithm Types Limitation
The maximum number of link aggregation algorithm types (Criteria) that can link up at the same time
depends on your Switch model. See Table 74 on page 163 for the list of Criteria that your Switch currently
supports.
The following table shows the maximum number of link aggregation algorithm types that can link up at
the same time.
For example, if your Switch has four link aggregation algorithm types that are currently linked up, the fifth
link aggregation algorithm type can only link up when link down occurs on one of the link aggregation
algorithm type.
30.2 Link Aggregation Status
Click PORT > Link Aggregation > Link Aggregation Status in the navigation panel to display the screen as
shown. See Section 30.1 on page 161 for more information.
