How to prevent concurrent zoning modification?

Hi,

is theoretically possible that two users logged in the same fc switch can engage some form of zoning-configuration change race condition?

If not, how does fabric os prevent this situation?

Regards,

Alberto

Depending on the interface used the last one to do the cfgenable wins.

If a user is applying a new zoneset and a second user executes a cfgenable, the second user will get a message saying that the fabric is busy preventing the the second config from being applied.

On the other hand, as dion.v.d.c posted, if there is time enough for the first cfgenable to be applied, the second user will be able to apply its own config without any issue.
