▀ Features and Functionality—Base Software

Description

The following thresholding models are supported by the system:
Alert: A value is monitored and an alert condition occurs when the value reaches or exceeds the configured high
threshold within the specified polling interval. The alert is generated then generated and/or sent at the end of
the polling interval.
Alarm: Both high and low threshold are defined for a value. An alarm condition occurs when the value reaches
or exceeds the configured high threshold within the specified polling interval. The alert is generated then
generated and/or sent at the end of the polling interval.
Thresholding reports conditions using one of the following mechanisms:
SNMP traps: SNMP traps have been created that indicate the condition (high threshold crossing and/or clear) of
each of the monitored values.
Generation of specific traps can be enabled or disabled on the chassis. Ensuring that only important faults get
displayed. SNMP traps are supported in both Alert and Alarm modes.
Logs: The system provides a facility called threshold for which active and event logs can be generated. As with
other system facilities, logs are generated Log messages pertaining to the condition of a monitored value are
generated with a severity level of WARNING.
Logs are supported in both the Alert and the Alarm models.
Alarm System: High threshold alarms generated within the specified polling interval are considered
―outstanding‖ until a the condition no longer exists or a condition clear alarm is generated. ―Outstanding‖
alarms are reported to the system's alarm subsystem and are viewable through the Alarm Management menu in
the Web Element Manager.
The Alarm System is used only in conjunction with the Alarm model.

IP Header Compression - Van Jacobson
Implementing IP header compression provides the following benefits:
Improves interactive response time
Allows the use of small packets for bulk data with good line efficiency
Allows the use of small packets for delay sensitive low data-rate traffic
Decreases header overhead
Reduces packet loss rate over lossy links
