Juniper ACX1000 Hardware Guide

All CoS features are supported at line rate.
The packet pipeline through an ACX Series router is shown in Figure 8 on page 9. Note
that the rate limiting is done with an integrated architecture along with all other CoS
functions. Scheduling and shaping are supported on the output side.

Protocols and Applications Supported by ACX Series Routers
Table 5 on page 10 contains the first Junos OS Release support for protocols and
applications on ACX Series routers. A dash indicates that the protocol or application is
not supported.
NOTE:
•
The [edit logical-systems logical-system-name] hierarchy level is not
supported on ACX Series routers.
•
TheACX Seriesroutersdoes not support per-family maximum transmission
unit (MTU) configuration. The MTU applied to family inet gets applied to
other families as well, even though it can be configured though CLI and
visible in show interface extensive output. The only way to use higher MTU
fora family is to manipulate the MTU, apply atinterface or family inet levels,
and let it calculate for each family automatically. For more information,
