3 Configuring LACP
This chapter contains a complete sample Link Aggregation Control Protocol (LACP)
configuration. To see details on the Command Reference.
LACP is based on the 802.3ad IEEE specification. It allows bundling of several physical
interfaces to form a single logical channel providing enhanced performance and redundancy. The
aggregated interface is viewed as a single link to each switch. The spanning tree views it as one
interface and not as 2 or 3 interfaces. When there is a failure in one physical interface, the other
interfaces stay up and there is no disruption.
Our implementation supports the aggregation of maximum 8 physical Ethernet links into a single
logical channel.
3.1 Configuring Link Aggregation
In this example, 3 links are configured between the two switches S1 and S2. These three links
are assigned the same administrative key (1) so that they aggregate to form a single channel 1.
They are viewed by the STP as one interface.
3.1.1 Configurations
S1
DUT1#configure terminal Enter the Configure mode.
DUT1(config)#lacp system-priority 2000
Set the system priority of this switch. This priority is
used for determining the system that is responsible
for resolving conflicts in the choice of aggregation
groups. A lower numerical value has a higher priority.
DUT1(config)#interface eth-0-1
Specify the interface (eth-0-1)to be configured and enter the
Interface mode.
DUT1(config-if)#no shutdown Enable the interface.
DUT1(config-if)# channel-group 1 mode active
Add this interface to channel group 1 and enable link
aggregation so that it can be selected for aggregation by the
local system.
