I did it. Worked without any issues in my case, VSP7k in a Switchcluster design as a core and ERS4k switches as Access.
In fact the VSP7k SW is based on the ERS5k code it runs very stable, so if you have done it with 5K switches
there is no magic to do it with VSP7k switches.

The order numbers for the VSP7k Fabric Interconnect Cables are AL7018001-E6 to AL7018008-E6.
You can have them from 0,6m up to 100m.

You have 4 rearPort connectors on each VSP7k. These ports are capable of different throuput.

In my expierence the VSP7k is extremly stable, didnīt have any problems in a SMLT setup.

@Dominik
@Paul L

Have you guys already configured 2 VSP7000's as a SMLT cluster over the rear ports, or only with the front SFP+ interfaces?

I currently trying to configure the IST over the rear ports, but with "rear-port mode" disabled I can't address the rear ports (ports 33 and up), with rear-ports enabled VLACP etc is autoconfigured and I get an error if I want to add the rear ports to my IST MLT.
Kind regards,

no havenīt done it with the rear ports. The feature was not implemneted in the SW code as I
setup a SMLT cluster with VSP7k switches.

Havenīt found a manual how to setup a switchclsuter over rear ports.
Did you enable the rear port raw mode ?

I think I'm on the right track by now..

I did some checking and noticed that when you enable rear port mode and reboot, the VSP makes a LACP group consisting of ports 34-36 and 38-40, grouped in MLT #32. I've been able to change the MLT type on this MLT from "normal" to "IST" without the box throwing errors.

I'm going to finish the config and hook up the 2nd unit, and see if it they can see each other and get the IST up.

Stay tuned... :)

OK, I have a configuration that seems to be working:

1) activate FI rear mode with "rear-ports mode enable" command
2) the switch warns about a partial reset and reboots after confirmation. As a result new interfaces are available (ports 33 till 40)
3) by default ports 33-40 have LACP enabled and are added to MLT 32. Disable LACP on the ports you need (refer to Resilient Datacenter solution technical design guide pg 19 for correct port numbers) When using the "FI UP" ports you need ports 34-36 and 38-40
4) configure your IST MLT like you normally would. You can recycle MLT 32 as it already has the FI ports assigned, or drop it and use MLT 1 instead.

Hope this helps...

I'd have to double check the next time I have an appointment with the customer, but I think the status led is off, and the up/down leds were flashing green rapidly..
