Release Information

Statement introduced before Junos OS Release 7.4.

Statement functionality updated in Junos OS Release 14.2, as described below.

Description

Configure the number of aggregated logical devices available to the router.

Starting in Junos release 14.2, for MX series routers, aggregated Ethernet interfaces created under a logical system can be individually named. Prior to 14.2, ae interfaces were named automatically (AE1, AE2) etc. upon setting the device count. This change allows administrators to use custom naming schemes. System resources are only allocated for named ae interfaces, regardless of how many were declared in the device count. (In Junos 14.2 and earlier, ae naming occurred automatically up to the number specified for device count, and system resources were allocated whether a given ae interface was used or not.)

Options

number—Set the number of aggregated logical devices that will be available for configuration.

Note

Starting with Junos OS Release 13.2, a maximum of 64 aggregated interfaces are supported for link aggregation of SONET/SDH interfaces. In releases before Junos OS Release 13.2, a maximum of 16 aggregated interfaces are supported for link aggregation of SONET/SDH interfaces.

For Junos OS Evolved, you can specify up to 512 aggregated Ethernet devices.

Range: 1 - 496. The upper limit for this value is system specific.

Range: 1 - 512 for Junos OS Evolved.
