Issues stacking x440 and x460-G2. No connection on second switch

jveronese — Sun, 25 Oct 2020 22:56:08 GMT

I have an X440 and an X460-G2. They are connected in a Ring Topology and seem to be successfully stacked after following the guide on Extreme’s site. However, only the switch that is the master (currently my X440) has connection. If I plug a computer into a port on the X460-G2 I get no link lights and no network connectivity. If I make the X460 the master the connection works, but all devices plugged into the X440 lose their connections. I can see both switches from my master, but can’t log in to the non-master switch as it just sits at AAA-pending. The only thing I can think of is that the X460 is on Edge Advanced license while the X440 is on Edge. Any help would be greatly appreciated.

jveronese,

Something i not clear.

Are they in stacking or ring (STP or EAPS)?

A topology drawing could hep to understand

Sorry, I’m new to stacking, so I do not know how to tell if it is STP or EAPS.

This is a rough drawing of what I have. Stacking port 1 on 440 is going to port 2 on the 460, with port 1 on the 460 going to port 2 on the 440.

jveronese,

Please review the stacking steps.

Here the steps from my cheat sheet:

Is it even possible to stack X440(-G1) with X460-G2?

At first I thought not but : https://gtacknowledge.extremenetworks.com/articles/How_To/Stacking-setup-involving-X460-G2-X460-G1-and-X440-switches

Oh, cool!

In this case the outputs of the following commands would be good to know.

show switch
show version
show stacking
show stacking configuration

Re: Issues stacking x440 and x460-G2. No connection on second switch

Hello,

the X440 is running 16.2.2.4 and the X460-G2 is running 15.7.1.4. I would de-stack them and update them on the same firmware (newest 16.x firmware).

Best regards
Stefan

jveronese,

As mentioned by Stefan and in the steps provided:

2-All nodes should run same sw version and be configured to boot from the same partition.

Sorry for the delay. I have updated the 460-G2 to 16.2.2.4. The issue persists. Any thoughts?

Greetings,

can you give the new output of “show switch” from both switches?

Maybe the X460-G2 has the wrong boot partition selected.

Even if you CAN stack these two switches together, I’m not so sure it’s a good idea. The X440 is really old and has a very weak feature set. The X460-G2 is a formidable beast compared to the X440 mouse.

In a stack, all switches are “downgraded” in functionality to that of the least competent switch. You end up with an X460-G2 with the functionality of an X440… If you only need the port capacity of the X440 added to the ports in the X460-G2, you might be better off not stacking them, but just connecting them together with a VLAN trunk (can even be a LAG for redundancy and more capacity).

Sorry for the delay. After wiping both switches back to defaults again I updated them to the latest XOS that the X440 can support. Then after redoing all the stacking commands it seems to be working now. Thank you for your help with this.

I have them in a stack as I am going to move my NAS and VM hosts to 10-gig using the SPF+ on the 460-G2, but use the X440 for most of my regular 1-gig connections as it has more ports.
