Chapter 4 LinkAggregation Feature

4.2 Configuration of the LinkAggregation Feature

The LinkAggregation feature can be configured with one of the following methods:

●Setting Up the /etc/opt/FJSVla/config File

●Using the /etc/opt/FJSVla/bin/fjla Command

●PRIMECLUSTER GLS 4.1 A30 or later is required to use the LinkAggregation feature. The FJSVla package contains the fjla command and a sample configuration file.

4.2.1Setting Up the /etc/opt/FJSVla/config File

This section explains how to create and modify the /etc/opt/FJSVla/config file to use the LinkAggregation feature. All LinkAggregation groups defined in the file will be automatically activated during the system boot. In this case, it is not necessary to run /etc/opt/FJSVla/bin/fjla command manually.

1) Create the /etc/opt/FJSVla/config file:

The /etc/opt/FJSVla/config.sample file is provided by the FJSVla package. Copy the sample file to create the config file.

# cp /etc/opt/FJSVla/config.sample /etc/opt/FJSVla/config

2) Modifying the /etc/opt/FJSVla/config file:

The following parameters must be specified in the /etc/opt/FJSVla/config file to use the LinkAggregation feature.

aggregator-interface

Specify the physical interface that represents the LinkAggregation group. The froup is a unit that performs data distribution and aggregation and also provides redundancy.

member-instance

Specify the interfaces that belong to the LinkAggregation group by instance number (except aggregator-interface). The valid number of members is 1 to 7. Multiple members can be specified by separating them with ":".

distribution mode

Specify the distribution mode used by the LinkAggregation group. See “4.1 About LinkAggregation Feature”for detailed information about each distribution mode. Specify any one of the following values:

1:Destination MAC address distribution

2:Destination IP address distribution
