Claim Text:
1. A method for facilitating traffic isolation in a switch, the method comprising: configuring one or more ports of the switch as members of first a traffic isolation zone, wherein a traffic isolation zone is a subset of ports in the switch and precludes a data flow not belonging to the traffic isolation zone from reaching a port within the traffic isolation zone; identifying that a data flow belongs to the first traffic isolation zone based on the subset of ports belonging to the first traffic isolation zone; in response to a port of the first traffic isolation zone being available, associating the data flow with the port as an output port; in response to the port not being available, determining whether a failover option for the first traffic isolation zone is enabled; and in response to the failover option being enabled, associating the data flow with a second port as an output port, wherein the second port is a member of a second traffic isolation zone, and wherein the second traffic isolation zone is distinct from the first traffic isolation zone.
