RMON Support

RMON is a major step forward in internetwork management. It defines a remote monitoring MIB that supplements MIB-II and provides the network manager with vital information about the internetwork. The Managed CenturyStack Hub Series fully supports RMON Management Groups 1, 2, 3, and 9, and users can set up for RMON Management using Web-Based Management, or SNMP Management. With these capabilities, Managed CenturyStack provides an effective and efficient way to monitor networks. For more detailed information, refer to Chapter 5 of this guide.

RMON Statistics Group

RMON group 1 is also recognized as Statistics Group, which contains the basic statistics for each monitored network. This group consists of a single table, with one entry for each monitored interface. The statistics group provides useful information about the load on a network and the overall health of the network.

Managed CenturyStack’s RMON Management enables users to set up Statistic Groups to record various statistics counters. The statistics group contains statistics measured by the probe for each monitored interface on the hub. These statistics take the form of free running counters that start from zero when a valid entry is created. Users can create up to 16 Ether Statistics entries. Syntax and semantic checking are performed to verify the value input by the user before it can be set to the Ether Statistics group. The valid Ether Statistics configuration data is saved in the system nonvolatile memory (NVRAM).

RMON History Group

RMON group 2 is also recognized as History Group, which is used to define sampling functions for one or more of the monitor’s interfaces. It contains two tables: historyControlTable, which specifies the interface and the details of the sampling function, and either HistoryTable, which records the data.

Managed CenturyStack RMON Management enables users to set up History Groups. The history control group controls the periodic statistical sampling of data from various types of networks. The history Control Table stores configuration entries that each define an interface, polling
