MLAG issue with HP server - Teaming LACP


Hi everyone,
My customer bought 4 X460 and 2 X670 int order to replace old network devices.
We created a two-tiers Mlag Network as described in "EXOS_User_Guide_16_1.pdf" on the page 300 (Figure 43).
We had some troubles to do that but everything was right some hours later.

Now, we have to migrate servers from old network to the new one and some of them are plugged with 2 wire. HP Teaming is used on and the team mode was "automatic" (so TLB with Fault tolerance if I'm not wrong) at the beginning.

I tried to create MLAG without sharing specific option but no success.
I tried to create MLAG and use L3 or L3_L4 algorithm but no success.

When I told you "no success", I just can't ping my server when both wire are plugged.

After that, I tried to create MLAG with LACP protocol.
Here the configuration :

Switch 1 :
code:

enable sharing 2:11 grouping 2:11 algorithm L3 lacp


code:

configure mlag peer "PAR-LTS-TOR_B-X460" lacp-mac 00:11:22:33:44:55


code:

enable mlag port 2:11 peer "PAR-LTS-TOR_B-X460" id 211



Switch 2 :
code:

enable sharing 2:11 grouping 2:11 algorithm L3 lacp


code:

configure mlag peer "PAR-LTS-TOR_A-X460" lacp-mac 00:11:22:33:44:55


code:

enable mlag port 2:11 peer "PAR-LTS-TOR_A-X460" id 211



Server :
I used the 802.3ad mode.

This configuration seems correct and I worked on since yesterday. I delete and configure it again about 15 times to be sure I didn't forget anything.

But still no success, I can't even ping my server with that kind of configuration.

I'm a little bit frustrated.

The only way we found is to configure NFT mode on server Teaming and delete MLAG configuration on switches... My customer is ok with that.

Any idea to help me ?

Thanks by advance.

Hi Arnaud,

One thing to check is that the vlans on the MLAG ports are also added to the ISC.

Can you post a topology, as well as the (sanitized) output of "show config vlan" and "show config vsm" from both MLAG peers?
