Can flow control be disabled on a vlan interface?
I tried in a simulator and It spits back "SIOCSFLOWCONTROL - Operation not supported by device" In the same simulator I can enable or disable it directly on the interface.
Example RC:
hostname toasterA ifgrp create lacp nfs_ifgrp -b mac e2b e1b vlan create -g off nfs_ifgrp 100 ifconfig e0M 192.168.1.100 flowcontrol none netmask 255.255.255.0 partner e0M up ifconfig nfs_ifgrp-100 192.168.0.100 flowcontrol none netmask 255.255.255.0 mtusize 1500 partner nfs_ifgrp-100 trusted up nfo route add default 192.168.0.1

You turn off flow control for the individual physical ports, not the trunked interface:
hostname toasterA ifconfig e2b flowcontrol none ifconfig e1b flowcontrol none ifgrp create lacp nfs_ifgrp -b mac e2b e1b vlan create -g off nfs_ifgrp 100 ifconfig e0M 192.168.1.100 flowcontrol none netmask 255.255.255.0 partner e0M up ifconfig nfs_ifgrp-100 192.168.0. netmask 255.255.255.0 mtusize 1500 partner nfs_ifgrp-100 trusted up nfo route add default 192.168.0.1

Okay, thanks. That is actually how they were on this unit and ifstat reports flowcontrol is on. I also, thanks Jeff, I should have mentioned I am currently on 7m 8.1.2p4
I actually noticed this when reading the 8.1.4 release notes and it mentioned a caution that you should review the order in the /etc/rc and if not in the recommended order, a panic may occur.
The 8.1 System Administration guide says it should be in this order:
hostname system_name ifgrp commands vlan commands ifconfig commands vfiler commands route commands [any other commands]
I guess that doesn't account for all situation?

Right, the machine I looked at here is 7-mode, running 8.1.4 and ifstat shows flowcontrol as disabled on the two ports.
Not sure about the ordering of the commands. Have you tried changing them?
hostname toasterA ifgrp create lacp nfs_ifgrp -b mac e2b e1b ifconfig e2b flowcontrol none ifconfig e1b flowcontrol none vlan create -g off nfs_ifgrp 100 ifconfig e0M 192.168.1.100 flowcontrol none netmask 255.255.255.0 partner e0M up ifconfig nfs_ifgrp-100 192.168.0. netmask 255.255.255.0 mtusize 1500 partner nfs_ifgrp-100 trusted up nfo route add default 192.168.0.1
Don't think I've ever tried that. Once difference is I don't have any vlan statements on mine.
