Link aggregation means that physical links with same
transmission media and transmission rate are “bound” together,
making them look like one link logically. This concept is also
known as Trunking. It allows parallel physical links between
the switches or between the switch and server to increase the
bandwidth in multiples and simultaneously. As a result, it
becomes an import technology in broadening link bandwidth and
creating link transmission flexibility and redundancy.
Aggregated link is also called trunk. If a port of trunk is
blocked or faulty, data packets will be distributed to other ports
of this trunk for transmission. If this port recovers, data
packets will be re-distributed to all the normal ports of this trunk
for transmission.
ZXR10 2920/2928/2952 supports a maximum of 15 aggregation
groups. In each aggregation group, number of links
participating in aggregation does not exceed eight. Links
participating in the aggregation must have same transmission
media type and same transmission rate.
Configuring LACP
This topic describes the configuration of link aggregation.
For configuration of link aggregation, perform the following
steps.
1. To Enable/Disable the LACP function, use command
set
lacp {enable|disable} in global configuration mode. This
is shown in Table 88.

function
Result: This Enable/Disable the LACP function.
Note: By default, the LACP function is disabled.
2. To add a specified port to the aggregation group, use
command set lacp aggregator <trunkid> add port
<portlist> in global configuration mode. This is shown in
Table 89.
