Using the BayStack 420 10/100/1000 Switch

BootP When Needed

Allows the switch to request an IP address if one has not already been set from the
console terminal. When selected, this mode operates as follows:

When the IP data is entered from the console terminal, the data becomes the
in-use address of the switch and BootP requests are not broadcast. The switch
can be managed using this in-band IP address.

When the in-band IP address is not set from the console terminal, the switch
broadcasts BootP requests until it receives a BootP reply containing an IP
address. If the switch does not receive a BootP reply that contains an IP
address, the switch cannot be managed in-band.

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 Always

Allows the switch to be managed only when configured with the IP address
obtained from the BootP server. When selected, this mode operates 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 switch does not receive a BootP reply, the switch cannot be managed
using the in-band IP address set from the console terminal.

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.
