LACP Blocked on HP Aruba 2920-48G Switch

I want to configure the two NICs on a Dell PowerEdge server as a team with LACP but to do so i also have to configure LACP on the switch.

I am using a HP Aruba 2920-48G Switch with the latest firmware (downloaded and installed last week) and have configured a static LACP for the two ports on the switch that the server is connected to and both ports are set to 'Auto'.

However, when i run command 'show lacp' one of the ports has a port status of 'Blocked' and a LACP status of 'Failure'.

Please can someone help with this so that both ports that are apart of this LACP group show as being up and have a LACP status of 'success'.

Thanks in advance for any help/advice given.

Hi

Can you show your config and show lacp command?

Kind regards

The config seems fine, maybe somthing rong on the server side.

The two nics on the server have been teamed as 802.3ad Link Aggregation using LACP. Both NICs have the latest firmware/drivers and the speed and duplex for both are set to auto negotiate.

I have not configured spanning tree at all on the switch and STP is currently disabled. Does this need to be enabled/configured?

I have seen this happen if the load balancing mechanism is mismatched between the LACP partners.

Hi,

Thanks for your help. Do you know how i go about checking if this is the case and if so then how to resolving this?

Show us Team ports configuration on server side...

Have you considered, eventually, to test Dynamic LACP instead of Static LACP, Switch side?

I did configure it as dynamic LACP to begin with but I got the same as i do now with static LACP - one of the ports went in to blocked status.

I've attached some screen shots showing the details/configuration of the team ports on the server side. It will only allow me to attach 5 so i will attach the rest in a separate reply.
