Usage Information

Related Commands

The flow teardown feature is coupled with the firewall feature. When default drop mode is enabled (command pnic default-drop-enable), the flow teardown is enabled by default. When default drop mode is disabled (pnic default-drop-disable), the flow teardown is disabled by default.

pnic default-drop-disableDisable firewall functionality. This is the default behavior.

pnic default-drop-enableEnable firewall functionality.
