NEW-GENERATION SERVER TECHNOLOGYpacket. Character send threshold is defined as the number of charactersfor which the BMC will wait before automatically transmittingthe SOL packet. The preceding two parameters are set using thefollowing commands:bmccfg solcfgparams --solcharaccumintervalbmccfg solcfgparams --solcharsendthresholdConfiguring PEF settings for SNMP alertingThe BMC can be configured—by matching against a set of PEFs—either to perform shutdown actions or to send event alerts. Alerts aredelivered as SNMP traps in the Platform Event Trap (PET) format.The Dell BMC supports sending alerts to as many as four destinationsover the LAN channel.The BMC can also be used to monitor voltage, fan rpm, temperature,processor health, chassis intrusion status, and the watchdogtimer. All of these events can be logged in the SEL and thestatus of the event log is also monitored. Administrators shouldconsult system documentation to determine which areas of thesystem can be monitored, because this typically varies from systemto system.To enable the BMC to send PEF alerts to alert destinations, usethe following command:Valid arguments for the --filter suboption include fanfail,voltfail, discretevoltfail, tempwarn, tempfail, intrusion,redundegraded, redunlost, procwarn, procfail, powerwarn,powerfail, hardwarelogfail, and autorecovery.For example, bmccfg pefcfgparams --filter=intrusion--filteralert=enable will enable filter alerting for the chassisintrusion event. Organizations can use an SNMP management console,such as ITA, to receive traps from such events. To disable alertsand perform only shutdown actions, use bmccfg pefcfgparams--filter=filtername --filteralert=disable.Configuring filters to perform local shutdown actionsBMC filters can also be used to perform local actions. To configure afilter to perform a local shutdown action, enter the following:bmccfg pefcfgparams --filter=filtername--filteraction=actionValid arguments for the --filteraction suboption includepowercycle, powerdown, reset, and none.PEFs can be configured both to perform a shutdown action andto send alerts. In such a case, the alert action is deferred until theshutdown action has been performed.bmccfg lanchannelaccess --pefalerting=enableTo disable the BMC from sending PEF alerts, use the followingcommand:bmccfg lanchannelaccess --pefalerting=disableManaging Dell servers with the BMCThe BMC can be a very powerful and flexible management device.Access to the extensive management capabilities of the BMC canbe streamlined through the Dell OpenManage Deployment Toolkit,and standard command-line tools can then be used to quickly checkserver status.To configure the IP address of the destination receiving theSNMP traps, use the following command (where x is a numberfrom 1 to 4):bmccfg lancfgparams --alertdest=x --destipaddr=IPAddressoftheconsolereceivingtrapsTo set the community string and host name identifier of thetrap, use the following command:Anusha Ragunathan is a software engineer in the Dell Product Group and is part of ateam that develops deployment tools for PowerEdge servers as part of the Dell OpenManagesystems management offerings.
