Configuring Node Defaults 4-5Secondary Alarm Output IDis used for a collecting node to send alarms to a second location other than that spec-ified by the Primary Alarm Output ID. This parameter has no function on non-collectingnodes.Secondary Alarm Output Pwdis a password that will be used if the Secondary Alarm Output ID is an address that isalso associated with a password. If so, both passwords must match.Collecting Nodeis a SmartSwitch 1800 or other Cabletron frame relay access device to which alarmsare sent from other Cabletron frame relay access devices. Any SmartSwitch 1800,9W004, FRX4000, or FRX6000 can be a collecting node; which nodes send theiralarms to a collecting node is determined by the Primary Alarm Output IDs and pass-words of the other nodes; these must match the Collecting Node ID and password oftheir collecting node.The number of nodes that can report to a collecting node depends on the number ofconnections that can exist on the collecting node. (A SmartSwitch 1800 supports upto 512 connections.) A connection on a collecting node is required for each reportingdevice.Do not configure a collecting node to send its alarms to anothercollecting node. The alarms will be ignored, due to a format mis-match.Max Congestionis a percentage of the SmartSwitch 1800 alarm buffer. If this level is exceeded, nomore alarms will be put into the buffer until it has reached the specified Min Con-gestion. (See that entry below and "Alarm Buffer" on page 22-2.)Min Congestionis a percentage of the SmartSwitch 1800 alarm buffer. As long as the percent of thebuffer that is full is below this level, alarms will always be placed into the buffer. (See"Alarm Buffer" on page 22-2.)Periodic Status Timersets the frequency with which the SmartSwitch will send a "heartbeat" alarm messagecontaining the date and time. The heartbeat serves as a verification that the Smart-Switch is operational.Line Idle Timeris a period that an SVC alarm connection will remain active after an alarm message issent. If no alarm is generated during this time, the alarm connection is cleared. ThePeriodic Status Timer (see that entry) determines the frequency with which routinestatus messages for this SmartSwitch will be sent. On a reporting (non-collecting)node, it is generally preferable to set the Line Idle Timer to a period longer than thePeriodic Status Timer, to give the system a chance to update itself. The timer is usuallyset to 0 on a collecting node.The Line Idle Timer is also affected by the value of Max Congestion (described on page4-5).
