NXA-ENET8-2POE Gigabit Ethernet Layer 2 PoE Switch
When incoming data frames are forwarded through the switch to a trunk, the switch must determine
to which port link in the trunk an outgoing frame should be sent. To maintain the frame sequence of
various traffic flows between devices in the network, the switch also needs to ensure that frames in
each conversation are mapped to the same trunk link. To achieve this requirement and to distribute
a balanced load across all links in a trunk, the switch uses a hash algorithm to calculate an output
link number in the trunk. However, depending on the device to which a trunk is connected and the
traffic flows in the network, this load-balance algorithm may result in traffic being distributed
mostly on one port in a trunk. To ensure that the switch traffic load is distributed evenly across all
links in a trunk, the hash method used in the load-balance calculation can be selected to provide the
best result for trunk connections. The switch provides four load-balancing modes as described in
the following section.
Aggregation Mode Configuration also applies to LACP (see the Configuring LACP section on
page 87).
Port identifier.
Controls whether LACP is enabled on this switch port. LACP will form an aggrega-
tion when two or more ports are connected to the same partner. LACP can form
up to 12 LAGs per switch.
The LACP administration key must be set to the same value for ports that belong
to the same LAG. (Range: 0-65535; Default: Auto) Select the Specific option to
manually configure a key. Use the Auto selection to automatically set the key
based on the actual link speed, where 10Mb = 1, 100Mb = 2, and 1Gb = 3.
Configures active or passive LACP initiation mode. Use Active initiation of LACP
negotiation on a port to automatically send LACP negotiation packets (once each
second). Use Passive initiation mode on a port to make it wait until it receives an
LACP protocol packet from a partner before starting negotiations.
To avoid creating a loop in the network, be sure you enable LACP before connecting the ports, and
also disconnect the ports before disabling LACP.
If the target switch has also enabled LACP on the connected ports, the trunk will be activated
automatically.
