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.
