Intel IXM5414E manual Link aggregation configuration example, 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
