If group parameter is specified in /etc/rc.conf it makes /etc/rc.d/netif restart to fail: # fgrep re0 /etc/rc.conf ifconfig_re0='192.168.1.20/24 group ifgrp' # ifconfig -v re0 re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> ether 00:1f:d0:5e:8f:57 inet 192.168.1.20 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (1000baseT <full-duplex>) status: active groups: ifgrp # /etc/rc.d/netif restart re0 Stopping Network: re0. re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> ether 00:1f:d0:5e:8f:57 media: Ethernet autoselect (none) status: no carrier ifconfig: SIOCAIFGROUP: File exists Starting Network: re0. re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> ether 00:1f:d0:5e:8f:57 media: Ethernet autoselect (none) status: no carrier The source of problem is that groups parameter persist when interface goes down: # /etc/rc.d/netif stop re0 Stopping Network: re0. re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> ether 00:1f:d0:5e:8f:57 media: Ethernet autoselect (1000baseT <full-duplex>) status: active # ifconfig -v re0 re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> ether 00:1f:d0:5e:8f:57 media: Ethernet autoselect (1000baseT <full-duplex>) status: active groups: ifgrp IMHO it's better to just ignore error when group param specifies groupname to which interface is already assigned.
