DLink DXS‑3600‑32S stack issue

[mdrabble]

I have 2 Dlink DXS‑3600‑32S with the EM Stacking Module as my core Fibre Switch.

 

I have enabled stacking on the switches and I can seem the stack in the web interface and cli - which suggests all is working ok and until now I have not had anything connected to the 2nd DXS until today.

 

Any edge switches in the 1st DXS are fine

 

Any edge switch i connect to the 2nd DXS, gets a link light but refuses to talk to the network.

 

I have a fluke tester and it confirms connection is good and can see VLAN packets but that is all that happens - it doesnt get a DHCP address and unable to ping anything.

 

 

Anyone any suggestions what I can look at next?

 

I have opened a ticket with DLink, but I can imagine response times being slow.....

 

Cheers

Are you connecting edge switches to both switches when you do not get any traffic or is a switch purely connected to one switch only. As it is stacking ports once the stack is configured and showing working properly it should just act as one switch . You should be able to connect a switch using 2 links and use them both without one getting blocked by spanning tree if a LAG is setup.

Just connecting the edge switches to a single DXS.

 

So If I plug an edge switch into the 1st switch in the stack it connects fine. - link lights, DHCP, etc....

If I then unplug the edge switch and connect to the 2nd switch in the stack, I get link lights but nothing else.

 

It is almost like a routing issue of some kind but since the switches are stacked and act as one I cannot see how it would be.......

Strange

vlans/ports configured on both ports set the same?

 

Anything show up on the logs?

 

Can you see any MAC addresses on the port when connected to 2nd switch or anything by looking at the lldp neighbors, sorry not familiar with these switches just trying to run through some steps :-)

All ports configures as Trunk ports and configure same on both DXS Switches.

 

Network tester shows VLAN/Data packets hitting the port, so traffic is hitting the port - it is literally like the light is on but no-one is home.

 

If all else fails may ditch the stack and connect them by 2x10Gb LAG connections

Very wierd, I'd be inclined to leave it stacked if possible and see what they come back with. A stacked switch is best really as they act as one meaning that you can utilise a LAG split across both switches without spanning tree blocking a link plus you have IP routing redundancy too.

Turned out to be a firmware issue - I had checked the DLink site and they only had upto 2.49 listed.

 

They sent me a link for 2.61 and soon as I applied it, everything started working after the reboot

Crikes, well glad you got it sorted :-)
