Hi,
I've been using a LACP trunk on my apu (with the three em(4)). On
top of which I have some vlans. I've been doing that for years and it's
working fine.
I thought about using aggr(4) instead (for no real reason). But the
aggr interface stays in "status: no carrier".
What I did is, I replaced my hostname.trunk0
trunkproto lacp trunkport em0 trunkport em1 trunkport em2
up
with a hostname.aggr0
trunkport em0 trunkport em1 trunkport em2
up
(and changing the parent in my hostname.vlan*). To apply the new
configuration, I just reboot.
My trunk0 which works is
trunk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:0d:b9:43:9f:fc
index 7 priority 0 llprio 3

And the aggr0 which doesn't come up is:

em2 port

status: no carrier
The only different thing I could see is the key (0x403c with trunk(4),
0x6 with aggr(4)) but I don't see how I could change it to try if it
matters.
Initially I thought the random lladdr from aggr(4) could be a problem
so I set it in the hostname.aggr0 file but it didn't help.
I don't see anything on the switch side I could change, and the log I
have is merely the ports going up or down when I reboot.
Any idea why aggr(4) stays in no carrier status?
Cheers,
Daniel
