Intel® Blade Server Ethernet Switch Module IXM5414E 253
Link aggregation configuration example
This section provides sample CLI commands showing how to configure the Intel® Blade Server
Ethernet Switch Module IXM5414E to support IEEE 802.3ad aggregated links. By defining a Link
Aggregation Group (LAG) you can treat multiple physical links between two end-points as one
logical link. The LAG will also be seen by management functions as a single link.
LAGs are used to increase both link bandwidth and reliability: they are often used for links to the
Internet or to shared servers. The script in the following example shows you how to configure and
enable two LAGs on the same switch.
Create and name two LAGs.
config lag create lag_internet
config lag create lag_server
When the switch creates the LAGs, it will assign logical interface IDs that you will use to
identify them in subsequent commands. Use the following command to find out what IDs have
been assigned:
show lag all
Add the physical ports to the LAGs. (Assume that lag_internet was assigned ID lag.1 and
lag_server was assigned ID lag.2.)
config lag addport lag.1 ext.1
config lag addport lag.1 ext.2
config lag addport lag.2 ext.3
config lag addport lag.2 ext.4
Enable both LAGs.
config lag adminmode lag.1,lag.2 enable
The previous command could have been issued instead as:
config lag adminmode all enable
