When I make changes to the switch’s configuration, they take effect but as soon as the
switch is powered off and on again the changes are lost
Explanation:
When you change the switch’s configuration, you are
changing the current active configuration that is running in RAM.
However, every time the switch starts-up it loads the configuration
that is stored in its Flash Memory. Therefore, if you make a change
to the configuration and want to keep it, you need to save the new
configuration to the switch’s Flash Memory.
Action:
Save the configuration changes to Flash Memory.
To check the status of the configuration, select
Configura-
tion>Software
.
The switch is unable to start-up—I am using the network management center as the boot
server
Explanation:
If the switch cannot start from Flash Memory
because, for example, the software in Flash Memory gets corrupted
somehow, it issues BOOTP requests on the network to look for a
boot server to provide the necessary software. This request contains
the switch’s MAC address, and any BOOTP server that has an entry
in its bootptab file containing the switch’s MAC address answers the
request and downloads the bootptab information corresponding to
the MAC address entry. However, because the network management
center does not have a bootptab file in which to specify things like
the filename of the software, this means that the switch cannot boot
from the network management center in this way because the BootP
requests issued from the switch do not contain any additional infor-
mation, such as the boot software filename. Note that this is not a
problem if you are using other boot servers that contain a bootptab
file, and where you have written the name of the software in the
bootptab.
Action:
Enter Maintenance Mode and manually issue a BOOTP
request including the filename; that is type the command:
BootP
<filename>
at the prompt and the switch is then booted with the
correct file from the boot server.
