Hi! if_lagg together with two multicast igb at more than 100 megabits led to 100% CPU interrupts one of the igb. The problem is not reproduced on other systems without igb adapters. So I gathered on lagg netgraph and with him there is no problem. Manual on russian: http://netlab.dhis.org/wiki/ru:software:freebsd:lagg_on_netgraph ng_lagg script http://netlab.linkpc.net/download/software/FreeBSD/ng_lagg/ng_lagg.sh Example Create: ng_lagg.sh start xxxLAGG em0 em1 igb0 Destroy: ng_lagg.sh stop ngeth0 Add network adapter: ng_lagg.sh if_add xxxLAGG igb1 Remove network adapter: ng_lagg.sh if_del em0 rc.d script http://netlab.linkpc.net/download/software/FreeBSD/ng_lagg/ng_lagg Example: ng_lagg_enable="YES" ng_lagg_interfaces="lagg0 xyzlagg" ng_lagg_lagg0="em0 em1" ng_lagg_xyzlagg="xl0 igb1" ifconfig_lagg0="inet 192.168.11.77 netmask 255.255.255.0" ifconfig_xyzlagg="inet 192.168.22.77 netmask 255.255.255.0" vlans_lagg0="vlan1234" create_args_vlan1234="vlan 1234" ifconfig_vlan1234="inet 192.168.0.77 netmask 255.255.255.0"
