• BootP or Last Address
BootP When Needed
Allows the switch to request an IP address if one has not already been set from the
console terminal. The Ethernet Switch 325/425 operates in the BootP When
Needed mode as described in the steps below:
• 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
This option allows you to manage the switch that has been configured with the IP
address obtained from the BootP server. The Ethernet Switch 325/425 operates in
the BootP Always mode as described in the steps below:
• 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.
Note: 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 When Needed
• BootP Always
•
BootP or Last Address
