Question

Is hierarchical QoS per VLAN supported on aggregated Ethernet (AE) interfaces?

Answer

Hierarchical QoS allows you to control QoS at multiple levels: the physical level, the logical level, and fine-grained control at the command-line level. It is useful for managing bandwidth congestion and link sharing in multi-service networks. For MX Series devices with AE interfaces, hierarchical QoS per VLAN is available over a link aggregation group (LAG) in Junos OS Release 9.4 and later. This support is only one-to-one active/backup. However, it can be supported across DPCs.

 

For more information, see MX Series Interface Module Reference

Hello - If memory serves me right, H-COS  is supported on LAG (egress only) on *MPC* too from JUNOS 12.3 onwards.
