physical-interface (DDoS Flow Detection)
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 at the physical interface flow aggregation level for the packet type.
Options
flow-bandwidth—Bandwidth for the flow at the physical interface level. Available only at the [edit system ddos-protection protocols protocol-group packet-type flow-level-bandwidth] hierarchy level.
Default: 20,000 packets per second
Range: 1 through 50,000 packets per second
flow-control-mode—Mode for how traffic in the detected flow is controlled at the physical 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 physical 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 physical interface level only when a DDoS policer is being violated and only when the policer violation is not discovered at the finer aggregation levels, logical interface or subscriber. Flows at the physical interface level are subsequently not searched again until a subsequent violation occurs that cannot be found at the subscriber or logical interface levels.
- off—Disable flow detection at the physical interface level so that flows are never searched at this level.
- on—Search flows at the physical 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.
