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
