/// Network flap detection & remediation

Flapping
ends here.

iFlapper detects unstable network elements — interfaces, routing neighbors and spanning tree bouncing up and down — and eliminates them before they take your network with them.

▲ input: Gi0/1 flapping output: stabilized ●

orange = unstable element on its way out · green = network carries on without it

What it detects

Not every fault can be caught by network devices or standard monitoring tools. iFlapper is built specifically to recognize the repeating up/down patterns of an unstable network:

IF up⇆down

Interfaces

Network device interfaces periodically changing status between on and off.

OSPF / EIGRP

Routing neighbors

Routing protocol neighbors periodically connecting and disconnecting. Supported: OSPF and EIGRP.

LDP session

MPLS neighbors

MPLS neighbors periodically connecting and disconnecting.

TCN storm

Spanning tree

Spanning tree periodically sending “topology change” notifications.

How it responds

Choose how much power to hand over: stay informed, or let iFlapper act.

Monitoring mode

Notify the administrator

When instability is detected, iFlapper sends the administrator a notification describing the fault and the action that should be taken to fix it. You stay in control of every change.

Changing mode

Eliminate the fault

iFlapper connects to the affected device via SSH and disconnects the unstable element — a network interface, an OSPF, EIGRP or MPLS neighbor — securing the stability of the rest of the network.

Automatic recovery cycle

1DetectInstability pattern identified from incoming events.

2ConnectSSH session opened to the affected device.

3Shut downThe unstable element is disconnected.

4WaitA configurable time limit passes.

5RestoreThe connection is brought back to its previous state; the administrator is notified of every finished task.

Inputs & platform

iFlapper monitors the network through three independent sources:

SYSLOG / UDP 514 SFLOW / telemetry FILE / watch changes

Runs anywhere

iFlapper is suitable for Windows, Linux and other operating systems or subsystems with Python 3.6 and a Java operating environment.
