SNMP-Based Security

The SNMP security feature allows you to set up network access control using
selective IP filtering. SNMP-based security limits administration access to the
switch, based on IP address filters.
For instructions on using the console interface (CI) to set up SNMP security, see
"TELNET/SNMP Manager List Configuration" on page 3-118.
See also Appendix E, "Quick Steps to Features," for configuration flowcharts that
can help you use this feature.

Flash Memory Storage

This section describes switch parameters that are stored in flash memory.

Switch Software Image

Your switch's software image is stored in flash memory. The flash memory allows
you to update your switch software image with a newer version, without changing
the switch hardware (see "Software Download" on page 3-121). An in-band
connection between the switch and the TFTP load host is required to download
the software image. If a BootP server is set up properly on the network and the
BayStack 450 switch detects a corrupted software image during the self-test, the
switch automatically uses TFTP to download a new software image.
