To change the default settings, we issue the command: switchstatuspolicyset. The first section of response to the command is the same as if we had issued the switchstatuspolicyshow command and displays a list of the current settings. Here we can see that the PowerSupplies line is defined to be Marginal if the switch is powered by one power supply. These default settings assume that the switch has two power supplies and that one has failed. Obviously, for a switch purchased with a single power supply, this is not valid. We are then prompted to enter the new values for each setting, starting with the DOWN value for the Faulty Ports, then the MARGINAL value for Faulty Ports. We press Enter to use default values; we are prompted for the next setting, and eventually, for the Power supply DOWN and MARGINAL values. We enter zero for the number of bad power supplies contributing to the DOWN status and zero for the number of bad power supplies contributing to the MARGINAL status. Indeed, because we are working with only one power supply, if it goes down, then the whole switch goes down. There is no marginal status. At the bottom of the Telnet display, after running the switchstatusshow command, we can see that the chassis status has changed from MARGINAL to HEALTHY. Email Configuration Use the Email Configuration tab to configure the destination e-mail ID to receive any alerts selected in the threshold configuration to deliver to e-mail as shown in Figure 1-134. Also on this tab, we are able to generally enable or disable the e-mail function for fabric Watch alerts, and send a test e-mail to ensure that the function is working. Chapter 1.
