Port fencing objects include the SAN, Fabrics, Directors, Switches (physical), Virtual Switches, Ports, as well as Port Types (E_port, F_port, and FX_port). Use port fencing to directly assign a threshold to these objects. When a switch does not support port fencing, a "No Fencing Changes" message displays in the Threshold field in the Ports table. If the port detects more events during the specified time period, the device firmware blocks the port, disabling transmit and receive traffic until you investigate, solve the problem, and manually unblock the port. Physical fabrics, directors, switches, port types, and ports display when you have the privileges to manage that object and are indicated by the standard product icons. 76 Fabric Watch Administrator's Guide 53-1001770-01
