Nortel Networks 350 manual Flash Memory Storage, BootP Automatic IP Configuration

Using the BayStack 350 10/100/1000 Series Switch

Flash Memory Storage

The BayStack 350 switch uses flash memory to store the switch software image. Flash memory allows you to update the software image with a newer version without changing the switch hardware.

An in-band connection between the switch and the TFTP load host is required to download the software image (see “Software Download” on page 3-70).

For information about connecting a console terminal for this procedure, see “Connecting the Console/Comm Port” on page 2-10.

Note: If a BootP server is set up properly on the network and the BayStack 350 switch detects a corrupted software image during the self-test, the switch automatically uses TFTP to download a new software image.

Certain configuration parameters, including the system characteristics strings, some VLAN parameters, the IGMP configuration parameters, and the MultiLink trunk names are stored in flash memory. These parameters are updated every 10 minutes or whenever a Reset command is executed. Powering off the switch within 10 minutes of changing these configuration parameters can cause the configuration parameters to be lost.

BootP Automatic IP Configuration

The BayStack 350 switch has a unique 48-bit hardware address, or MAC address, that is printed on a label on the back panel. You use this MAC address when you configure the network BootP server to recognize the BayStack 350 switch BootP requests. A properly configured BootP server enables the switch to automatically learn its assigned IP address, subnet mask, IP address of the default router (default gateway), and software image file name.

For an example of a BootP configuration file, see Appendix F, “Sample BootP Configuration File.”
