[OpenIndiana-discuss] no external connectivity on link

Please verify that your host and switch have compatible activity settings.
Compatible meaning, they are not the same ;-)

I set the switch for active and the hosts for passive. You will receive
inconsistent results like the host being reachable at times and unreachable
at other times if they are not properly configured.

In juniper speak, you can check with something like this. Just replace your
AE number:

root at brdr0.sf0> show configuration interfaces ae1 aggregated-ether-options
lacp {
    active;
}

or view the config with this:

root at brdr0.sf0> show lacp interfaces ae1
Aggregated interface: ae1

I don’t have any IOS boxes with LACP at the moment or I would dump those
processes as well....

Ok, thanks for that. Here's what those commands you mentioned show:

root at openindiana:/export/home/bluethundr# dladm show-aggr -L
LINK        PORT         AGGREGATABLE SYNC COLL DIST DEFAULTED EXPIRED
aggr1       e1000g0      yes          no   no   no   no        no
--          e1000g1      yes          no   no   no   no        no

root at openindiana:/export/home/bluethundr# dladm show-aggr -x
LINK        PORT           SPEED DUPLEX   STATE     ADDRESS
PORTSTATE
aggr1       --             1000Mb full    up        0:25:90:b:34:0     --
            e1000g0        1000Mb full    up        0:25:90:b:34:0
attached
            e1000g1        1000Mb full    up        0:25:90:b:34:1
attached

so, it looks like the ports are attached, up, NOT in sync, not
defaulted and not expired. Apparently I need to be able to get them in
sync, but I'm not sure  how to do that.

>Do you mean it can ping itself?

Yep, that's what I was trying to say. The host can ping itself and as
of now I can ping the aggregated address from the host itself and from
another host on the network.

I basically left it alone overnight and when I went back to it this
morning I could ping external hosts from this machine and ssh into it
on that aggregated address whereas last night I could not which is why
I emailed the list! :)

Maybe it just takes a little while to work after it's setup?

Yep!

I'll have a look at your LACP article and see what I can do. Thanks
for your input!

Thanks and best regards,
Tim
