NETGEAR 8800 User Manual PSUCTRL-2 : 30.50 Normal -10 0-50 60 The switch monitors the temperature of each component and generates a warning if the temperature exceeds the normal operating range. If the temperature exceeds the minimum/maximum limits, the switch shuts down the overheated module. Power Supply Temperature To view the current temperature of the power supplies installed in the NETGEAR 8800 series switches, use the following command: show power {} {detail} The following is sample output of temperature information: PowerSupply 1 information: ... Temperature: 30.1 deg C ... Using the Event Management System/Logging We use the general term, event, for any type of occurrence on a switch that could generate a log message or require an action. For example, a link going down, a user logging in, a command entered on the command line, or the software executing a debugging statement, are all events that might generate a log message. The system for saving, displaying, and filtering events is called the Event Management System (EMS). With EMS, you have many options about which events generate log messages, where the messages are sent, and how they are displayed. Using EMS you can: • Send event messages to a number of logging targets (for example, syslog host and NVRAM) • Filter events per target, by: • Component, subcomponent, or specific condition (for example, BGP messages, IGMP.Snooping messages, or the IP.Forwarding.SlowPathDrop condition) • Match expression (for example, any messages containing the string "user5") • Matching parameters (for example, only messages with source IP addresses in the 10.1.2.0/24 subnet) • Severity level (for example, only messages of severity critical, error, or warning) • Change the format of event messages (for example, display the date as "12-May-2005" or "2005-05-12") • Display log messages in real time and filter the messages that are displayed, both on the console and from Telnet sessions • Display stored log messages from the memory buffer or NVRAM 214 | Chapter 8.
