Nortel Networks 2500 Series manual BootP or Default IP, BootP Always, BootP or Last Address

Switch management features 71

•BootP or Last Address

ATTENTION

Whenever the switch is broadcasting BootP requests, the BootP process eventually times out if a reply is not received. When the process times out, the BootP request mode automatically changes to BootP Disabled mode. To restart the BootP process, change the BootP request mode to any of the three following modes:

•BootP or Default IP

•BootP Always

•BootP or Last Address

BootP or Default IP

The Ethernet Routing Switch 2500 Series operates in the BootP or Default IP mode (the default mode) as follows:

•After the switch is reset or power cycled, if the switch has a configured IP address other than 0.0.0.0 or the default IP address, then the switch uses the configured IP address.

•If the configured IP address is 0.0.0.0 or the default IP address (192.168.1.1/24), then the switch attempts BootP for 1 minute.

•If BootP succeeds, then the switch uses the IP information provided.

•If BootP fails and the configured IP address is the default, then the switch uses the default IP address (192.168.1.1/24).

•If BootP fails and the configured IP address is 0.0.0.0, then the switch retains this address.

BootP Always

This option lets you manage the switch that is configured with the IP address obtained from the BootP server. The Ethernet Routing Switch 2500 Series operates in the BootP Always mode as follows:

•The switch continues to broadcast BootP requests, regardless of whether an in-band IP address is set from the console terminal.

•If the switch receives a BootP reply that contains an in-band IP address, the switch uses this new in-band IP address.

•If the BootP server is not reachable, you cannot change the in-band IP address until the BootP mode is set to BootP Disabled. However, after a period of a few minutes (appoximately 10 minutes), the switch automatically enters the BootP Disabled mode. You can then configure the IP address using the CLI.
