Help creating MLAG to 2 x X670V switches using a single 10GB port on each

[gonzoessex]

Hello,

I've got a VMware Host with 2 x 10Gb going into 2 X670V switches (1 port in each) where I set them up as a MLAG (LACP).  I've done this before and the port on the switches are usually the same, for example if it's port 10 on both switches I would use this:

Switch1
enable sharing 10 grouping 10 algorithm address-based custom lacp
enable mlag port 10 peer "SWITCH-2" id 10

Switch2
enable sharing 10 grouping 10 algorithm address-based custom lacp
enable mlag port 10 peer "SWITCH-1" id 10

And this will work fine.

Now I have a VMware host that goes into different ports and I'm not sure which part is I need to change.

So now I have the 10GB ports going into port 15 on switch 1 and port 22 on switch 2.  Would the following work as I think it's the "id" part is the remote port to bind with?

Switch 1
enable sharing 15 grouping 15 algorithm address-based custom lacp
enable mlag port 15 peer "SWITCH-2" id 22

Switch 2
enable sharing 22 grouping 22 algorithm address-based custom lacp
enable mlag port 22 peer "SWITCH-1" id 15

Thanks

What command can I use to see the current ID's used?

Thanks that makes sense, so enable mlag port 15 peer "SWITCH-2" id 500 means enable the mlag for port 15 and bind with anything on id 500 on Switch-2?

Yes, that's right. The MLAG ID ties ports on one peer to ports on the other peer using the same MLAG ID. These ports should be going to the same downstream device that puts ALL ports to BOTH switches in the SAME LAG.

To see what IDs are in use,
show config vsm
show mlag port

Some other things to keep in mind with MLAG:
1) Any VLANs added to an MLAG port on one MLAG peer MUST be added to the corresponding ports (by MLAG ID) on the other MLAG Peer

2) Any VLANs added to an MLAG port on one MLAG peer MUST be added to both sides of the ISC link.

Hope that helps!

The ID number needs to match across both MLAG peers, so whatever you configure the ID number as one the one switch, you need to configure the same ID number on the other side for the ports on the other switch you want to bind together.
