period, and other parameters. Once samples are taken, the data is stored as an entry in a media-specific table. Each entry defines one sample, and is associated with the history Control Entry that caused the sample to be taken. Each counter in the ether History Entry counts the same event as its similarly named counterpart in the Ether Stats Entry, except that each value here is a cumulative sum during a sampling period.

The user can create up to 16 History Control Entries.

RMON Alarm Group

RMON Alarm Group is used to define a set of thresholds for network performance. Managed CenturyStack RMON Management enables users to set up Alarm Groups. The Alarm Group periodically takes statistical samples from variables in the probe and compares them to thresholds that have been configured. The alarm table stores configuration entries that define a variable, polling period, and threshold parameters. If a sample is found to cross the threshold values, an event is generated. This function generates one event as a threshold and is crossed in the appropriate direction. No more events are generated for that threshold until the opposite threshold is crossed.

Managed CenturyStack provides the threshold control function to support the RMON Alarm Group. Up to 16 Alarm Control Entries can be created. The syntax and semantic checking is performed to verify the value input by the user before it can be set to the object of the Alarm Group. The valid Alarm Group configuration data is saved into the system NVRAM.

Managed CenturyStack periodically monitors the threshold value of counter objects that have been specified as the RMON Alarm Variable. The associated RMON event is raised and the proper event action is performed when the value of counter object crosses its threshold value as specified in the RMON Alarm Threshold object.

RMON Event Group

RMON Event Group supports the definition of events. An event is triggered by a condition located in the MIB, and an event can trigger an action defined elsewhere in the MIB. An event may also cause informa- tion to be logged in this group and may cause an SNMP trap message to
