Extreme side: Assuming ports being assigned are not untagged on any VLANs or in use by anything else
Assuming port 5,6,7,8:
Enable sharing 5 grouping 5,6,7,8 lacp
Add to VLANS we need to route:
configure VLANname1 add ports 5 tagged
configure VLANname2 add ports 5 tagged
Cisco commands:
Assuming 2x core switches chained, ports 37 and 38 each.
interface range g1/0/37-38,g2/0/37-38
description temp connection to extreme core
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 48 mode active
interface port-channel48
description temp connection to extreme core
switchport trunk encapsulation dot1q
switchport mode trunk
3/22/12 update: We've finally retired the old Extreme switches. I am happy to say that this LACP trunk config performed perfectly for nearly 5 months to tie a new Cisco infrastructure to an old Extreme one.

Hey Toby this article helped me out tons in trunking my 450e to my HP switch
Quick question - I need to add to additional Trunk lines on my extreme (have already added the ports on the HP end)
Do i just run the
Enable sharing 20 grouping 20,21,22,23 lacp
command again with the extra ports in the list or is there a separate command?
Enable sharing 20 grouping 20,21,22,23,24,25 lacp?
thanks
Brian

Hi @Brian!
I'm not sure if you can add ports by issuing the same command, but if that doesn't work for you feel free to re-do the config with the following:
disable sharing 20
enable sharing 20 grouping 20,21,22,23,24,25 lacp
You may need to re-do your trunk since you'll be deleting the "virtual" port. After you're done, you can use the
show ports sharing
command to verify the config. It should work as the 450a supports up to 8 ports per group.
Good luck!

Thanks toby I assume you mean re -add the port 20 to the vlans as it may disapear once i delete the port?
Yup!
Hi Toby,
Question for you,
Do you happen to have any experience with the Extreme AP4511?
I have 15 of these spread over two floors.
Connected to Extreme 450e Switch.
I have 6 uplinks via LACP to my main HP switch.
We have a 100/100mb Internet line.
At any one time we have a minimum of 100 clients connected via various devices mainly iphones/ipads/macbooks etc.
I have noticed that when we have 10 -15 people trying to access via one AP point the AP point basically craps out.
Looking for someone who knows these AP points and can advise on how to utilize what we have to work more streamlined.
Thanks
Hey Brian, sorry I didn't get back to you sooner. Unfortunately I don't have much for experience with that AP. I will say that in an unmanaged scenario it can be difficult to get devices from swapping back and forth between APs, and channel overlapping can make it worse.
If you haven't already, I'd start with making sure close APs (including from each floor) don't have overlapping channels and that your coverage is good. There is great professional equipment for this, but if you want to take a quick peek there are things out there like WiFi analyzer for Android devices.
Good luck!
The admin was providing the explanation is very clear and very useful for all readers. I want more different details about this topic and I like the post.
