example of an object might be a port that can be enabled or disabled,
or a counter that can be read.
Consider a counter object that records the number of frames
transmitted onto the network. The MIB would contain the following
entry:
a3ComEtherStatTxBytes OBJECT-TYPE
SYNTAX
ACCESS
STATUS
DESCRIPTION
::= {a3ComEtherStatEntry 15}
In simple terms, this tells us:
1 The formal name of the counter is 3ComEtherStatTxBytes.
(3Com, Ethernet, Statistics, Transmit Bytes).
2 The counter is to be found in a table called 3ComEtherStat.
3 The counter is the 15th column in the table.
It is not necessary to know and understand the MIB in order to manage
a network. With most management facilities the MIB is transparent.
But if you do have an understanding of how the various management
features are derived, you will be in a better position to make full use of
the information presented.
If you would like to have a copy of the MIB, contact 3Com using one of
the means listed in Appendix B.
