2 Configuring Static Link Aggregation
This chapter contains a complete sample static Link Aggregation configuration. To see details on
the commands used in this example, refer to the Command Reference.
Link Aggregation is based on the 802.3ad IEEE specification. It allows bundling of several
physical interfaces to form a single logical channel providing enhanced performace and
redundancy. The aggregated interface is viewed as a single logical link to each switch. The
Protocol Module(except LACP module) 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 8 physical Ethernet links at most in a single logical
channel.
2.1 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 so that they aggregate to form a single channel 1. They
are viewed by the Protocol Module(except LACP) as one interface.
2.1.1 Configurations
S1
DUT1#configure terminal Enter the Configure mode.
DUT1(config)#interface eth-0-5
Specify the interface (eth-0-5)to be configured and enter the
Interface mode.
DUT1(config-if)#no shutdown Enable the interface.
DUT1(config-if)#static-channel-group 1
Add this interface to a static channel group 1 and enable link
aggregation so that it can be selected for aggregation by the
local system.
DUT1(config-if)#exit Exit the Interface mode and enter the Configure mode.
DUT1(config)#interface eth-0-6
Specify the interface (eth-0-6)to be configured and enter the
Interface mode.
