The Interface/Port Flapping threshold setting controls the analysis of interfaces and ports that are continually going up and down. Unstable analysis monitors SNMP link down traps to identify a flapping interface or port and then generates a notification to report that the interface or port is unstable.
The VMware Smart Assurance IP Availability Manager User Guide provides information about how the IP Availability Manager concludes that an interface or port is unstable. An interface or port is also known as a network adapter.
Default values for the Interface/Port Flapping threshold setting lists the Interface/Port Flapping threshold setting parameters.
| Parameter |
Default value |
Description |
|---|---|---|
| LinkTrapThreshold |
0 to 10 Default: 3 |
Number of SNMP link down traps that must be received within the LinkTrapWindow for the IP Availability Manager to consider the interface or port flapping. A value of 0 turns off flapping analysis. |
| LinkTrapWindow |
30 to 3600 seconds Default: 300 seconds (5 minutes) |
Window of time that is used to monitor flapping analysis of an interface or port. If the number of link down traps equals or exceeds the LinkTrapThreshold during this window of time, the interface or port is considered to be flapping. |
