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?

Hope this helps

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.

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

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.
