Introduction
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.
For a description of static and dynamic link aggregation (LACP), see
LACP Channel Group” on page 20.5
. For an LACP configuration example, see
Chapter 20, Link Aggregation Introduction and Configuration
Note

supports IEEE 802.3ad link aggregation and uses the Link
Aggregation Control Protocol (LACP). LACP does not interoperate with devices
that use Port Aggregation Protocol (PAgP).
Note
LACP does not perform load balancing. The LACP algorithm is based on the
packet flow. Link aggregation (LAG) hashes the source and destination MAC
address, IP address and UDP/TCP ports to select a port on which to send a
packet. So packet flow between a pair of hosts always takes the same port
inside the LAG.
The net effect is that the bandwidth for one packet stream is restricted to the
speed of one link in the LAG. For example, for a 2 Gbps LAG that is a
combination of two 1 Gbps ports, one flow of traffic can only ever reach a
maximum throughput of 1 Gbps.
For information about load balancing see the
command.
