5-5. MIB to Be Installed
BKM-FW50 that can be used for Information Display
installs MIB-2.
MIB-2 is the most representative standard MIB. It is
installed in various network products.
The statistical information on the amount of network
traffic or the number of transmitted and received packets is
defined, and the change or transition can be monitored by
polling the information periodically.
Additionally, the management items to be installed can be
defined using a TCP/IP device so as to get the information
effective for the monitoring of the network communication
state.
Refer to RFC1213 for the detailed definition of MIB-II.
5-6. Information to Be Notified on Trap
In software version 2.0 or later, the Information Display
into which the software is inserted mounts a function that
transmits error information to BKM-FW50, so an error trap
is installed. Authentication Trap is also installed.
5-7. ID Talk
