Hi,

When I want to enable Active / Active teaming on my HP server, it fails with the following msg: 802.3ad link aggregation (lacp) has failed. Action: Ensure all ports are connected to LACP aware devices

HP team settings:
Team type selection: 802.3ad Dynamic with Fault Tolerance
Transmit Load Balancing Method: Destination IP Address

Installed the latest fireware, Driver of Broadcom card + latest version of NCU.

Switch config:
interface Port-channel1
 description vers serveur XXX
 switchport trunk native vlan 30
 switchport trunk allowed vlan 3,10-13,30
 switchport mode trunk
 switchport nonegotiate
 spanning-tree portfast trunk
 

interface GigabitEthernet1/0/1
 description vers serveur XXX
 switchport trunk native vlan 30
 switchport trunk allowed vlan 3,10-13,30
 switchport mode trunk
 switchport nonegotiate
 speed nonegotiate
 no cdp enable
 channel-group 1 mode active
 
 interface GigabitEthernet2/0/1
 description vers serveur XXX
 switchport trunk native vlan 30
 switchport trunk allowed vlan 3,10-13,30
 switchport mode trunk
 switchport nonegotiate
 no cdp enable
 channel-group 1 mode active

Any help would be appreciated ?

Thanks
HL

I would suggest changing hp load balancing settings to L2 from L3
and I would recommend trying to switch cisco lacp to passive

Are you absolutely certain that the two physical links are functional?

lacp should come up even with one functional link

LACP- port Ch will only work if there even # links are up between to connected devices.
for ex. if you have 4 link between 2 switches and 1 link fails the team will drop to 2 links.

Made some progress on this issue:
might be related to VLAN native.

On the HP NCU tool: Two VLANs defined (VLAN11: Prod, VLAN12: Backup). You have to define a VLAN native. Is set to 11 (not sure ist's good idea)
>> Once I set to 11, the Teaming LACP came up
>> BUT I can't ping any Host in the same broadcast domain or on different subnet

What I found:
On internal switch trunk port (connected to HP server) set new native VLAN to 11.
On internal switch trunk port (connected to external switch) didn't set new native VLAN (kept default=1)

I believe my problem is related to the use of VLAN / native VLAN in the HP NCU tool:
Anyone have same config: multiple VLAN set on a teamin ?
How do you deal with Native VLAN ?
How do you force the HP server to get an IP from a specific VLAN when it boot up ?

Thanks

Try this on eth ports cisco, and make sure you enabled lacp on HP ports (lacp enable)

switchport mode dynamic desirable

Added new VLAN on HP NCU with ID 1, set as Default.
On Cisco switch, removed new native VLAN (default native VLAN all along the L2=1)
These actions Fixed my problems.
