unreachable, or it may have been deleted by software but

 

not yet removed from memory at the device. An alarm

 

that is underCreation is in the process of being

 

configured (possibly by another management station),

The fields in the Events Watch display include:

Index

This is a number that uniquely identifies an entry in the

 

event table; an index number is assigned when an event

 

is created. These numbers are extremely important, as

 

 

they are the means by which an event is associated with

 

an alarm or a packet capture filter. As with alarms, these

 

index numbers are user-defined and can be assigned

 

 

according to any indexing scheme that works for you.

 

 

Index numbers are permanently assigned to their

 

 

associated events; however, numbers made available by

 

the deletion of existing events can be assigned to new

 

 

events, as needed. Note that indices 2000 to 4999 are

 

 

reserved and unavailable.

 

LastTime

Indicates the last time this event was triggered. Note that

 

this information is static once it is displayed, and the

 

 

LastTime field will not be updated unless you close, then

 

open, the Alarms/Events window, or click on

.

Type

Indicates the type of response that will be generated if

 

the event is triggered: log, trap, or log & trap. A type of

 

“none” indicates that occurrences of the event will not be

 

logged and no trap will be sent; however, note that this

 

field does not indicate whether or not there are any

 

 

actions associated with the selected event.

 

Description

This is a user-defined text description used to identify

 

 

the event and/or the alarm or packet capture that

 

 

triggers it.

 

The button at the bottom of the screen provides access to the log which lists the occurrences of an event.

Note that the information provided in this screen is static once it is displayed; for
