Nortel Networks 2500 Series manual BootP Disabled, BootP or Last Address, Default BootP setting

72System configuration software features

If an IP address is not currently in use, these actions take effect immediately. If an IP address is currently in use, these actions take effect only after the switch is reset or power cycled.

BootP Disabled

This option lets you manage the switch by using the IP address set from the console terminal. The Ethernet Routing Switch 2500 Series operates in the BootP Disabled mode as described in the following steps:

•The switch does not broadcast BootP requests, regardless of whether an IP address is set from the console terminal.

•The switch can be managed only by using the in-band switch IP address set from the console terminal.

BootP or Last Address

This option lets you manage the switch even if a BootP server is not reachable. The Ethernet Routing Switch 2500 Series operates in the BootP or Last Address mode as described in the following steps:

•When you specify the IP data from the console terminal, the IP address becomes the in-band address of the switch. BootP requests are not broadcast. You can manage the switch using this in-band IP address.

•When you do not specify the in-band IP address from the console terminal, the switch broadcasts BootP requests until it receives a BootP reply containing an in-band IP address. If the switch does not receive a BootP reply that contains an in-band IP address within 10 minutes, the switch uses the last in-band IP address it received from a BootP server. This IP information is displayed in the Last BootP column.

If the IP address specified as the in-band IP address is not currently in use, these actions take effect immediately. If an IP address is currently in use, these actions take effect only after the switch is reset or power cycled.

Default BootP setting

With Release 4.1 software, the default operational mode for BootP on the switch is BootP or Default IP. The switch requests an IP address from BootP only if one is not already set from the console terminal (or if the IP address is the default IP address: 192.168.1.1).

Flash memory storage

Switch software image storage

The Ethernet Routing Switch 2500 Series uses flash memory to store the switch software image. The flash memory lets you update the software image with a newer version without changing the switch hardware (see "Upgrading software" (page 229)). An in-band connection between the switch and the TFTP load host is required to download the software image.
