#!/bin/sh while true; do ifconfig ix0 down; ifconfig ix1 down; sleep 1; ifconfig ix0 up; ifconfig ix1 up; sleep 5; done this script is working for 3 hours without problems... will let script working over night and will generate traffic through openbsd box... i noticed that when ifconfig up is executed that interrupts on cpu0 went to 30% for that moment ... don't know is this is expected
