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!

for lacp one side should be configured as active, second as passive.
sometimes, it is possible to configure both sides active and devices will negotiate the status for each other.
i think you should also create ling aggregation group on hp.
because when one device is configured without link aggregation, the second will disable all ports save first one.

I hate these HP switches if they are what I think they are, but they do work.

On HPs you have to set ports as Tagged to trunk multiple VLANs, or they act as access ports.  To bundle links together there is a way of grouping them.  I haven't got VPN access to hand but I will try to look tomorrow for you on some working switches

Hi Guys,

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.
