Introduction

Overview This chapter provides an alphabetical reference of commands used to configure a
static channel group (static aggregator) and dynamic channel group (LACP
channel group, etherchannel or LACP aggregator). Link aggregation is also
sometimes referred to as channeling.
NOTE
Aggregation Control Protocol (LACP). LACP does not interoperate with devices that use
Port Aggregation Protocol (PAgP).
Link aggregation does not necessarily achieve exact load balancing across the links.
The load sharing algorithm is designed to ensure that any given data flow always goes
down the same link. It also aims to spread data flows across the links as evenly as
possible.
For example, for a 2 Gbps LAG that is a combination of two 1 Gbps ports, any one flow
of traffic can only ever reach a maximum throughput of 1 Gbps. However, the hashing
algorithm should spread the flows across the links so that when many flows are
operating, the full 2 Gbps can be utilized.
For a description of static and dynamic link aggregation (LACP), and configuration
examples, see the
