First time MLT setup questions
« on: August 01, 2017, 02:56:23 PM »
I am wanting to set up an MLT between a stack of two 4850GTS-PWR+ switches (one link from each switch) and a single 3549GTS-PWR+.  There is already a single link between them. 

First question I have a couple of questions regarding this setup:  How can I set up this MLT from the 4850GTS side without needing to be physically present at the other side without and without losing connectivity to it?  On the 4850GTS side I already have the MLT set up on two unused ports, I'm just not sure how to proceed with the remote switch.

Second question, I have seen on the how to on this site that I need to run Learning Disable.  I saw an Avaya document that said Learning Enable.  What is the difference here?

Also, I will make sure bdpu is enabled on all MLT ports as well as STP disabled.

Need a lab to try it out first really, but I guess not a lot of people have that available to them...

When I'm doing something remotely I will set a switch restart off before doing any work, that way if there is any mis-configuration you only have to wait 30 minutes or whatever you set before it comes back to normal.

make sure autosave is turned off on the switch first though, or its not going to help!

Hi,

you can create this MLT on both sides (remotely), as long you have the same link-speed over all links and tagging enabled, without Spanning Tree enabled (Example CLI: mlt x enable member 1/49-50 learning disable).

In pure Avaya environment all NNI-Links between network nodes needs to have STP disabled.

Good luck

Set up tagging (type and VLANS) on all ports involved identical.  Keep your existing link as-is.
Build your MLT either command-line of via EDM on one side.  You will need to validate Spanning Tree is disabled on the ports after you bond them together.  Note, the existing link can remain up this entire time.
Next, go to your other switch and repeat this.  Once you have verified both sides are up and are in MLT mode, then plug the second link in.
