I've setup several aggregates in the past. Just to make sure, are you working with your network team on this? The aggregate has to be setup on the switch end as well or it won't work. Both connections have to be going to the same switch. I've had trouble in the past with network guys who didn't know how to set it up properly on their end.

Sometimes the network guys also won't know what you mean by "aggregate" since it can sometimes go different names depending on vendors. I had to actually send our network guy the Wikipedia link so that he could go research how to do it on their Cisco switch -- Link aggregation - Wikipedia, the free encyclopedia

Depending on the network infrastructure in the data center sometimes network teams will freak out on you about this as well. I tried to set it up one data center, and the network team rejected it because they only had 2 GB links going between their switches in the data center and they were concerned I would flood their links.

Good luck! Once it's setup it works like a charm, and is persistant across reboots. I did this for a backup server in one data center that was getting bogged down at night due to so much traffic from various servers. After I set that up it knocked the backup times almost in half. It was awesome watching how fast the data was transferring.

Example syntax would be similar to this:

Code:

dladm create-aggr -d bge0 -d bge1 2
 
dladm show-aggr ### (to verify you set it up properly)
 
#### (Then do your ifconfig commands as necessary, you shouldn't have to reboot to make sure it's working. 
# Once you know it's working update your /etc/hostname.* files in Solaris 10 or ipadm in Solaris 11 and 
# reboot to make sure it continues to work across reboots.)
### Example:
ifconfig aggr2 plumb
ifconfig aggr2 ................

SYSTEMD-NETWORKD.SERVICE(8)                                  systemd-networkd.service                                  SYSTEMD-NETWORKD.SERVICE(8)

NAME

       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS

       systemd-networkd.service

       /lib/systemd/systemd-networkd

DESCRIPTION

       systemd-networkd is a system service that manages networks. It detects and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see systemd.link(5).

       systemd-networkd will create network devices based on the configuration in systemd.netdev(5) files, respecting the [Match] sections in
       those files.

       systemd-networkd will manage network addresses and routes for any link for which it finds a .network file with an appropriate [Match]
       section, see systemd.network(5). For those links, it will flush existing network addresses and routes when bringing up the device. Any
       links not matched by one of the .network files will be ignored. It is also possible to explicitly tell systemd-networkd to ignore a link by
       using Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition
       from the initrams and to restart the service without breaking connectivity. This also means that when configuration is updated and
       systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up
       manually.

CONFIGURATION FILES

       The configuration files are read from the files located in the system network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
