Abstract

A method includes receiving a FLOGI message sent by a device seeking to log on to a network, wherein the device is in a same zone as reachable devices already logged into the network; in response to the FLOGI message, sending to the device a FC_ID, receiving from the device a query, including the FC_ID, for a list of devices with which the device can communicate, in response to the query, sending to the device an empty list of reachable devices with which the device can communicate within the same zone; after sending the empty list, programming, at least, an access control list (ACL) including information about the device; and after the ACL is programmed, triggering a RSCN message to be sent to the device to cause the device to, for the first time, obtain information about the reachable devices.
