Introduction
This Chapter describes configuration of uplink interfaces aggregation.
Link aggregation (IEEE 802.3ad) is a technology that allows multiple physical links to be combined into
one logical link (aggregation group). Aggregation group has high throughput and is very reliable.
Fig. 16.1. Multiple Physical Links Combined to an Aggregation Group
The terminal supports two interface aggregation modes: static and dynamic. Static aggregation implies
that all communication links of a group are always active. As for dynamic aggregation, link activity is
dynamically determined during operation via LACP protocol.

Description
static Link aggregation protocol is not used
lacp
LACP is used
The terminal has several algorithms to balance load within aggregation groups.
