Alcatel Unleashed

Hello,

I explain you my problem.
I have two computer rooms (RG01 and RG02).
I have a stack of 4 switches 6865 distributed in the computer rooms (2 in RG01, 2 in RG02 connected in multimode fiber).
In each computer room, I also have a stack of 2 switches 2360 connected in aggregate (one fiber link in each room).
I have configured a split-helper on the 2360 stack of the RG01 to disable the 6865 of the RG02 room in case of separation of the core stack.

My problem is that if I simulate the separation of the core, only unit 3 is deactivated but not my unit 4... how can I also automatically deactivate unit 4 knowing that I can only configure one split-protection on the core side?

I hope I was precise enough...

Thanks for your help

Laetitia.

Here is a diagram for further explanation

After checking, only unit 3 (RG02-C1) is in "Split-Topology" status.

COEUR_RG01/RG02 > show virtual-chassis topology

4 Slave Running 4 50 1 94:24:e1:f7:3a:55

But, after checking, all fiber interfaces of both units are disabled so the "Split Protection" feature works for both units (RG02-C1 and RG02-C2).

If it can help someone, here is the configuration I made:
On the core:
virtual-chassis split-protection linkagg 1
virtual-chassis split-protection admin-state enable

On the edge switch:
virtual-chassis split-protection helper linkagg 1
virtual-chassis split-protection helper admin-state enable
