Abstract
A networking device includes a port, and a management module that identifies fabric subsets that include networked devices that can exchange information with each other, detects that a networked device was uncoupled from the networking device, and modifies the fabric subsets. A Fibre Channel switch includes ports, zones and a management module. Each zone includes subsets of devices coupled to the ports, and permits the subset of devices to exchange information with each other. The management module detects when a device becomes uncoupled from a port and automatically updates the zones to restrict the device from exchanging information with other devices. A method includes identifying fabric subsets in a network, selecting a fabric subset that includes networked devices that are permitted to exchange information with each other, detecting that one of the networked devices has become uncoupled from the network, and automatically modifying a portion of the network fabric.
