Syntax
Hierarchy Level
Release Information
Statement introduced in Junos OS Release 12.3.
Description
(MX Series routers with MPCs only) Configure flow bandwidth, flow control mode, or flow detection mode for flow detection at the logical interface flow aggregation level for the packet type.
Options
flow-bandwidth—Bandwidth for the flow at the logical interface level. Available only at the [edit system ddos-protection protocols protocol-group packet-type flow-level-bandwidth] hierarchy level.
Default: 200 packets per second
Range: 1 through 30,000 packets per second
flow-control-mode—Mode for how traffic in the detected flow is controlled at the logical interface level. Available only at the [edit system ddos-protection protocols protocol-group packet-type flow-level-control] hierarchy level.
- drop—Drop all traffic in flow.
- keep—Keep all traffic in flow.
- police—Police the traffic to within its allowed bandwidth.
flow-detection-mode—Mode for how flow detection operates at the logical interface level when a policer has been violated. Available only at the [edit system ddos-protection protocols protocol-group packet-type flow-level-detection] hierarchy level.
- automatic—Search flows at the logical interface level only when a DDoS policer is being violated and only when the flow causing the policer violation is not discovered at the finer flow aggregation level, subscriber. When the suspicious flow is not found at this level, then the search moves to a coarser level of flow aggregation (physical interface). Flows at the logical interface level are subsequently not searched again until the policer is no longer violated at the coarser level, and a subsequent violation occurs that cannot be found at the subscriber level.
- off—Disable flow detection at the logical interface level so that flows are never searched at this level.
- on—Search flows at the logical interface level, even when no DDoS protection policer is currently being violated. Monitoring continues at this level regardless of whether a suspect flow is identified at this level.
