monitor all statistics,

Because the SuperStack II Hub 10 stack supports only one Ethernet
segment, there is one interface that can gather RMON information.
For those resources created by the RMON agent itself during startup,
the owner string will be set to 'monitor'.
RMON monitoring requires considerable processing power. During
extremely heavy traffic, the SuperStack II Hub 10 Management Module
can become swamped and may not process data. Usually, this has a
negligible effect. If you want to be sure to collect all data, we
recommend you use the Advanced RMON Module with its faster
processor and increased memory. Also you should use the Advanced
RMON Module if you need memory-hungry statistics; for instance
prolonged packet capture sessions.
The Management Information Base (MIB)
At the heart of all network management is the Management
Information Base or MIB. It cannot be stressed too much how
important it is to understand the nature of the MIB if you are to achieve
the maximum potential offered by the management system.
The MIB is a formal structured set of data describing the way the
network is functioning. The management software (the agent) accesses
the set and abstracts the information it requires. The agent will also
store data in the MIB.
The organization of the MIB is such that an SNMP network
management package (for example, Transcend) without specific
knowledge of a particular device can manage that device at an
adequate level. This is known as Generic Network Management.
In simple terms, a MIB consists of a large number of objects which
represent features of the equipment to be controlled and managed. An
