Phase 2: Connect and Configure
(I apologize for the formatting, blogger ate all of my nice formatting)
Turn off all switches
Connect TenGigE interfaces in ring topology
Power on switch 1 (master) and wait til done booting
Power on switch 2 and wait til done booting
Power on switch 3 and wait til done booting

Phase 3: Test
After this you will see many system messages and also see
1
System is busy with warm backup, please wait ...
This is the master switch rebooting the slave switches as they join the IRF.
You can check the setup like so

3 3 Ten-GigabitEthernet3/1/1 Ten-GigabitEthernet3/1/2
<HP>
You should also configure each switch’s Master Priority. A higher number means it will have more chances of being the master. This is done with:
123
irf member 1 priority 32
irf member 2 priority 31
irf member 3 priority 30
Confirm that the switch is a master with:
123456789
disp irf
Switch Role Priority CPU-Mac Description
*+1 Master 32 b8af- 6123-6123 ----- 2 Slave 31 b8af- 6123-6123 ----- 3 Slave 30 b8af- 6123-6123 -----
--------------------------------------------------
* indicates the device is the master.
+ indicates the device through which the user logs in.
The Bridge MAC of the IRF is: b8af-6123-6123
Auto upgrade : yes
Mac persistent : 6 min Domain ID : 1
After you have suffered through all this you can go ahead and configure your switches or, more correctly, single large switch (as the switches will be now act as one).

sysname mylanswstack1
interface Vlan-interface1
ip address 10.0.0.2 255.255.255.0
Save all your configurations. Shut off the switches and restart them, and make sure they come up in the proper IRF Master/Slave roles.
