Cabletron Systems 1800

Configuring Node Defaults 4-5

Secondary Alarm Output ID

is 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 fu nction on non-collecting

nodes.

Secondary Alarm Output Pwd

is a password that will be used if the Secondary Alarm Output ID is an address that is

also associated with a password. If so, both passwords must match.

Collecting Node

is a SmartSwitch 1800 or other Cabletron frame relay access device to which alarms

are sent from other Cabletron frame relay access devices. Any SmartSwitch 1800,

9W004, FRX400 0, or F RX6000 can be a collec ting no de; whi ch nod es send their

alarms to a collecting node is determined by the Primary Alarm Output IDs a nd pa ss-

words of the other nodes; these must match the Collecting Node ID and passw or d of

their collecting node.

The number of nodes that can report to a collecting node depends on the number of

connections that can exist on the collecting node. (A SmartSwitch 1800 supports up

to 512 connections.) A connection on a collecting node is required for each reporting

device.

Do not configure a collecting node to send its alarms to another collecting node. The alarms will be ignored, due to a format mis-match.

Max Congestion

is a percentage of the SmartSwitch 1800 alarm buffer. If this level is exceeded, no

more 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 Cong es tion

is a percentage of the SmartSwitch 1800 alarm buffer. As long as the percent of the

buffer that is full is below this level, alarms will alw ays be placed into the buffer. (See

"Alarm Buffer" on page 22-2.)

Periodic Status Timer

sets the frequency with which the SmartSwit ch w ill send a "heartb eat" alar m message

containing the date and time. The heartbeat serves as a verification that the Smart-

Switch is opera tional.

Line Idle T imer

is a period that an SVC alarm connection will remain active a fter an alarm message is

sent. If no alarm is generated during this time, the alarm connection is cleared. The

Periodic Status Timer (see that entry) determines the frequen cy with which routine

status messages for this SmartSwitch will be sent. On a reporting (non-collecting)

node, it is generally preferable to set the Line Id le Timer to a period longer than the

Periodic Status Timer, to give the sy stem a chance to update itself . The timer is usually

set to 0 on a collecting node.

The Line Idle Time r is also affected by the value of Max Congestion (described on page

4-5).
