The new FLASH image(s) will be used after the ESP-2 hub reboots.
5.8 Displaying or Changing Configurable Features
The Configurable Features display includes the current settings of the features
described in Table 14 on page 19.
When the ESP-2 serial hub is reinitialized, all configurable features are restored to
their default settings.
To view or change configurable features:
1. From the Top Menu, enter
0
to select Server Configuration.
2. From the Server Configuration menu, enter
3
to select Configurable features.
3. The current state (enabled or disabled) of each feature is displayed. You are
prompted to change the state for each feature. Enter
y
for yes or
n
for no.
For example, if the SNMP feature is currently enabled, you will be prompted to
disable that feature. If you enter
y
, SNMP will be disabled; if you enter
n
, SNMP
will remain enabled.
5.9 Downloading a Configuration File
To ease the task of configuration, the ESP-2 hub supports file-based configuration.
The Configuration Download operation initiates the loading of a configuration file
from a TFTP server. The commands in the file are processed and the configuration is
then updated. See
on page 32 for more information.
To download and process a configuration file:
1. From the Top Menu, enter
0
to select Server Configuration.
2. From the Server Configuration menu, enter
4
to select Configuration File Download.
3. You are prompted to specify the TFTP server IP address and the pathname of the
configuration file. Enter those values.
The outcome of the configuration update will be displayed. If an error occurred with
the TFTP address or file pathname, the message will indicate a time-out condition. If
an error was encountered in the configuration file, the display includes the command
line number and the erroneous entry.
The EEPROM configuration is updated immediately, but some changes may not take
effect until the next reboot. The display will indicate if a reboot is required.
