Setting the Number of Aggregated Ethernet Interfaces on the Chassis

By default, no aggregated Ethernet interfaces are created. You must define the number of aggregated Ethernet interfaces by including the device-count statement at the [edit chassis aggregated-devices ethernet] hierarchy level:

[edit chassis]
aggregated-devices {
ethernet {
device-count number;
}
}
[edit interfaces]
ae x{
aggregated-ether-options {
link-protection;
}
unit logical-unit number {
family inet {
address address;
}
}
}

The maximum number of aggregated devices you can configure is 128. The aggregated interfaces are numbered from ae0 through ae127. For information about configuring aggregated devices, see the JUNOS System Basics Configuration Guide.

You must also specify the constituent physical links by including the 802.3ad statement at the [edit interfaces interface-name fastether-options] or [edit interfaces interface-name gigether-options] hierarchy level; for more information, see Configuring Ethernet Link Aggregation. For a sample configuration, see Example: Configuring Aggregated Ethernet Interfaces.
