Hierarchical Schedulers on Aggregated Ethernet Interfaces Overview
On MX Series routers, you can apply hierarchical schedulers on aggregated ethernet bundles using interface sets. This feature enables you to configure a group of virtual LANs (VLANs) and control their bandwidth. This feature is supported at egress only.
You can configure interface sets for aggregated Ethernet (AE) interfaces created under static configurations. You can configure class-of-service parameters on AE interfaces, in either link-protect or non-link-protect mode. You can configure these parameters at the AE physical interface level. The CoS configuration is fully replicated for all AE member links in link-protect mode. You can control the way these parameters are applied to member links in non-link-protect mode by configuring the AE interface to operate in scaled mode or replicate mode.
The link membership list and scheduler mode of the interface set is inherited from the underlying aggregated Ethernet interface over which the interface set is configured. When an aggregated Ethernet interface operates in link protection mode, or if scheduler mode is configured to replicate member links, the scheduling parameters of the interface set are copied to each of the member links.
If the scheduler mode of the aggregated Ethernet interface is set to scale member links, the scheduling parameters are scaled based on the number of active member links (scaling factor is 1/A where A is the number of active links in the bundle) and applied to each of the AE interface member links.
To configure an interface set, include the interface-set statement at the [edit class-of-service interfaces] hierarchy
level.
To apply scheduling and queuing parameters to the interface
set, include the output-traffic-control-profile profile-name statement at the [edit class-of-service interfaces interface-name interface-set interface-set-name] hierarchy level.
To apply an output traffic scheduling and shaping profile for
the remaining traffic to the logical interface or interface set, include the output-traffic-control-profile-remaining profile-name statement at the [edit class-of-service
interfaces interface-name] hierarchy level
or the [edit class-of-service interfaces interface-name interface-set interface-set-name] hierarchy
level.
