Creating a LAG/MLT and LACP on 2 Extreme 8404C core ports

Hello All,

I've had a look at the various Extreme documents regarding LACP on a LAG etc. I can't seem to make this work for some reason.

What I have is 2x 8404C 10GB core switches and I wish to use ports 2/23 and 2/24 as a LAG with LACP.

I've tried from the Web GUI and CLI but seem to have different results on each switch.

What commands and in which order should I be doing this?

I have:

1. Disable the ports.

2. Created the MLT as the file attached.

3. Added VLAN 1 as untagged and any other VLANs as tagged as needed.

4, Enabled LACP on the ports.

5. Enabled the ports.

Is this the correct procedure?

what is I need is a Port Group with LACP.

Thanks,

If you want create MLT with LACP over vIST peers:

1. configure "lacp smlt-sys-id", must be the same in both peers

2. enable LACP at global

3.- configure MLT (smlt):

mlt <mlt id>
mlt <mlt id> encapsulation dot1q
interface mlt <mlt id>
lacp key <key id>
lacp enable
smlt
exit

4. Configure lacp on ports, the key must the same defined in the MLT

interface gigabitethernet <port>
lacp key <key id>
lacp aggregation enable
lacp timeout-time short
lacp enable
exit

5. Configure VLANs in port.

If the port and lacp works, the vlans will be added to the MLT.

This way works for me.

Regards!!
