Configure Aggregated Devices

JUNOS software supports the aggregation of physical devices into defined virtual links, such as the link aggregation of Ethernet interfaces defined by the IEEE 802.3ad standard. To define the virtual links, you need to specify the associations between physical and logical devices within the [edit interfaces] hierarchy, and assign the correct number of logical devices by including the device-count statement at the [edit chassis aggregated-devices ethernet] and [edit chassis aggregated-devices sonet] hierarchy levels:

[edit chassis]

aggregated-devices {

    ethernet {

        device-count number;

    }

    sonet {

        device-count number;

    }

}

The maximum number of Ethernet logical devices you can assign is 128. The range is 1 through 128. The maximum number of SONET logical interfaces is 16. The range is 1 through 16. For more information on physical and logical interfaces using aggregated links, including sample configurations, see the JUNOS Internet Software Configuration Guide: Network Interfaces and Class of Service.
