HNB Gateway in Wireless Network
indicative of larger, more severe issues. The purpose of thresholding is to help identify potentially severe conditions so
that immediate action can be taken to minimize and/or avoid system downtime.
The system supports Threshold Crossing Alerts for certain key resources such as CPU, memory, number of sessions etc.
With this capability, the operator can configure threshold on these resources whereby, should the resource depletion
cross the configured threshold, a SNMP Trap would be sent.
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.

ANSI T1.276 Compliance

ANSI T1.276 specifies security measures for Network Elements (NE). In particular it specifies guidelines for password
strength, storage, and maintenance security measures.
ANSI T1.276 specifies several measures for password security. These measures include:
 Password strength guidelines
 Password storage guidelines for network elements
 Password maintenance, e.g. periodic forced password changes
These measures are applicable to the systems and the Web Element Manager since both require password
authentication. A subset of these guidelines where applicable to each platform will be implemented. A known subset of
guidelines, such as certificate authentication, are not applicable to either product. Furthermore, the platforms support a
variety of authentication methods such as RADIUS and SSH which are dependent on external elements. ANSI T1.276
