Using the Console Interface

309978-D Rev 01

3-13

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-band 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.

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.
