----------------------

1. Show available devices
   # dladm show-dev

2. Configuring an aggregation with key 1 (note, "/etc/aggregation.conf" created)
   # dladm create-aggr -d bge0 -d bge1 1

3. Plumb and set IP (note, still need to create /etc/hostname.aggr1 to persist)
   # ifconfig aggr1 plumb 192.168.33.2 up

3. Show aggregation
   # dladm show-aggr

4. To show the available interfaces that can be used: 
   # dladm show-dev

5. Then just create a /etc/hostname.aggr1 and use ifconfig and hostname as you would with any other interface.

6. To add/remove an interface:

   # dladm add-aggr -d <interface> 1
   # dladm remove-aggr -d <interface> 1

7. Create the trunk as specified below
   # dladm create-aggr -P L2 -l passive -T short -d e1000g0 -d e1000g1 1

8. To view the LACP details follow the example below:

   # dladm show-aggr -L

   key: 1 (0x0001) policy: L2      address: X:XX:XX:XX:XX:XX (auto)
                   LACP mode: passive      LACP timer: short
      device    activity timeout aggregatable sync  coll dist defaulted expired
      e1000g0   passive  long    yes          yes   yes  yes  no        no
      e1000g1   passive  long    yes          yes   yes  yes  no        no

9. To view aggregate statistics follow the example below:

   # dladm show-aggr -s
    key: 1  ipackets     rbytes    opackets    obytes                    %ipkts %opkts
            Total        398054    41821394    278529    28661590
            e1000g0      282639    28945342    1365      171084          71.0    0.5
            e1000g1      23084     2724062     84099     8609560         5.8     30.2

10. This is what I did to configure the switch. Each port on the switch must be configured the same as GigabitEthernet1/1. 
Be sure to configure the ports first, before creating interface port-channel 

	port-channel per-module load-balance
	port-channel load-balance dst-mac
	!
	interface Port-channel1
 	 switchport
  	 switchport mode access
 	 no ip address
        !
        interface GigabitEthernet1/1
 	 switchport
         switchport mode access
         no ip address
         lacp port-priority 4096
         lacp rate fast
         channel-group 1 mode active
        !

* Update 2/25/2007: Certain versions of the IOS for the Cisco Catalyst 6509 do not suppport Etherchannel trunks 
  faster than 1 Gigabit. This will require an IOS upgrade for the full bandwidth of the LACP trunk to be used.
