ESC mismatch, Distributed Config DB

One switch says:  23 Te 12/0/24 Up ISL segmented,(ESC mismatch, Distributed Config DB)(Trunk Primary)

The other switch says:  23 Te 54/0/24 Up ISL segmented,(ESC mismatch, Distributed Config DB)(Trunk Primary)

 

I saw that means, "The DCM Configuration DB is different on both the ends of ISL," but I have no idea how to resolve that.

 

 

VDX-6720s running 4.1.3b.

I appreciate the attempt, but they don't appear to be related at all.

Re: ESC mismatch, Distributed Config DB

Hello MHammett,

 

The ESC is an acronym standing for "Exchange Switch Capabilities" and occurs when an ISL (Connection between two VDX switches) comes online. Both switches require to have the same settings when it comes to fabric communications. especially timers, flow-control, and a number of other tick-boxes. If only one of them is different the switches will segment and not form a fabric.

 

Check with your vendor and provide them with the "copy support" out of both switches so they can determine what the difference is and how to correct it.

 

It's almost impossible to find out via this forum as there are so many variables in play here.

Kind regards,
