Setting up port Trunking between Cisco cat 3650 and HP GbE2c blade switch using LACP
Hi,
We are trying to setup an LACP trunk (active) between four ports (0/19-22) on a cisco catalyst 3650 switch and four ports (21-24) on a HP GbE2c Blade switch.
We have placed the following config on the cisco,
-------------------------- SNIP------ ---------- --------
!
port-channel load-balance src-dst-ip
no file verify auto
spanning-tree mode pvst
spanning-tree extend system-id
!
vlan internal allocation policy ascending
!
interface Port-channel15
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode access
!
interface GigabitEthernet0/1
switchport access vlan 10
switchport mode access
!
-------------------------- SNIP------ ---------- --------
!
interface GigabitEthernet0/18
switchport access vlan 10
switchport mode access
!
interface GigabitEthernet0/19
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode access
channel-group 15 mode active
!
interface GigabitEthernet0/20
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode access
channel-group 15 mode active
!
interface GigabitEthernet0/21
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode access
channel-group 15 mode active
!
interface GigabitEthernet0/22
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode access
channel-group 15 mode active
!
interface GigabitEthernet0/23
switchport access vlan 10
switchport mode access
!
-------------------------- SNIP------ ---------- --------
Where VLAN 10 is our production network
On the HP I have simply gone into the web interface and enabled LACP Active via. Config->Layer2->LACP on ports 21-24.
I plugged in the four ethernet cables and the cisco shows port 19 active but the others (20, 21 and 22) disabled (presumaby error disabled)
Anyone any ideas what Im doing wrong?
Thanks very much in advance for any replies!

I have found the solution to this issue.
Thanks for the replies, I have awarded points equally just for effort.
The problem was that the adminkey was different on all the ports, to successfully setup the trunk you have to set them to the same via switch console (over ssh) with the command
/cfg/l2/lacp/
port 21
adminkey xxx
up
port 22
adminkey xxx
up
port 23
adminkey xxx
up
port 24
adminkey xxx
apply
save
Where xxx is any number.
