Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status Fabric Watch does not record any event until the event persists for a length of time equal to the port persistence time If the port returns to normal boundaries before the port persistence time elapses Fabric Watch does not record any event To set the port persistence time refer to Setting the port persistence time on page 69 Port fencing A port that is consistently unstable can harm the responsiveness and stability of the entire fabric and diminish the ability of the management platform to control and monitor the switches within the fabric Port fencing is a Fabric Watch enhancement that takes the ports offline if the user defined thresholds are exceeded Supported port types include physical ports E_Ports optical F_Ports FOP_Ports copper F_Ports FCU_Ports and Virtual E_Ports VE_Ports NOTE Port fencing is not enabled by default You must manually enable port fencing Refer to Port fencing configuration on page 70 for instructions When a port that has exceeded its user defined thresholds is fenced by the software the port is placed into the disabled state and held offline After a port is disabled the user must manually enable the port for frame traffic to resume on the port System resource monitoring System resource monitoring enables you to monitor your system s RAM flash and CPU You can u
