Fabric without zoning

Hi, I never met fabrics without zoning before. But we have a customer who build two switch fabrics without zoning.

Can you answer me, in this case may server connected to one switch work with library connected to another switch?

Re: Fabric without zoning

switch> defzone --show
Default Zone Access Mode
        committed - All Access
        transaction - No Transaction

sample output of a switch with default all access

All switches in all access mode.

Re: Fabric without zoning

Thus in this case all servers on a switch have access to all targets in the fabric.

Are you sure? it`s meaning that zoning is not requirement for this case?

Re: Fabric without zoning

If there's no zoning at all in the fabric, yes I'm sure.

But I didn't say it was a good thing ... A best practice is to ALWAYS implement zoning in a fabric.

Kind regards,

David,

if the defzone noaccess is configured will have the result that the customer can switch off the switches because no traffic flow will be possible ;-)

In other words:

Without a zoning DB you need to have defzone allaccess.
