Release Information
Statement introduced before JUNOS Release 7.4.
The [edit dynamic-profiles profile-name] hierarchy added in JUNOS Release 9.3.
The $junos-cos-scheduler-dropfile-low, $junos-cos-scheduler-dropfile-medium-low, $junos-cos-scheduler-dropfile-medium-high, $junos-cos-scheduler-dropfile-high, and $junos-cos-scheduler-dropfile-any predefined variable added in JUNOS Release 9.4.
Description
Within the drop-profile map, specify the name of the drop profile to use for random early detection (RED) for a specific packet-loss priority (PLP) level and protocol type. A drop profile maps a fill level (fullness of a queue) to a drop probability (probability that a packet will be dropped). When a packet arrives, RED checks the queue fill level. If the fill level corresponds to a nonzero drop probability, the RED algorithm determines whether to drop the arriving packet.
You enable RED by applying a drop profile to a scheduler.
You configure drop profiles statically (at the [edit class-of-service drop-profiles] hierarchy level).
Options
-
profile-name—Name of the drop profile.
-
variable—One of the following JUNOS predefined variable that is replaced with a value obtained from the RADIUS server when a subscriber authenticates over the subscriber interface to which the subscriber access dynamic profile is attached:
- $junos-cos-scheduler-dropfile-low—Name of the drop profile for PLP level low and protocol any, specified for a scheduler configured in a dynamic profile for subscriber access.
- $junos-cos-scheduler-dropfile-medium-low—Name of the drop profile for PLP level medium-low and protocol any, specified for a scheduler configured in a dynamic profile for subscriber access.
- $junos-cos-scheduler-dropfile-medium-high—Name of the drop profile for PLP level medium-high and protocol any, specified for a scheduler configured in a dynamic profile for subscriber access.
- $junos-cos-scheduler-dropfile-high—Name of the drop profile for PLP level high and protocol any, specified for a scheduler configured in a dynamic profile for subscriber access.
- $junos-cos-scheduler-dropfile-lny—Name of the drop profile for PLP level any and protocol any, specified for a scheduler configured in a dynamic profile for subscriber access.
