[EX] Hierarchical CoS is not supported on EX-series switches



Article ID: KB20735 KB Last Updated: 05 Mar 2017Version: 2.0
The purpose of this article is to inform users that Hierarchical C0S is not supported on EX Switch platforms.  This is a generic Junos OS feature but currently not supported on EX Switch platforms.
Hierarchical CoS enables you to apply traffic shaping parameters (which can include a delay-buffer bandwidth) and packet transmission scheduling parameters (which can include buffer management parameters) to an individual subscriber interface rather than to all interfaces configured on the port.
Hierarchical CoS is currently supported on Juniper routing platforms running Junos OS, but not on EX Switches.

Please contact Juniper support (JTAC) if there are any questions concerning the future support for this feature for EX Switching platforms.
