Basic LS2020 Configuration Tasks
Special Consideration: Running Scripts Separately
When you enter configuration data, two scripts are invoked automatically that prompt you for basic
configuration information (see bullets below). If youerr in entering information inresponse to script
prompts, you can run the scripts again separately. To do so, enter the name of the script you want to
run at the bash# (root) prompt or the single-user ($) prompt.
• /bin/settimezoneinfo—Sets the time, date, daylight savings method, and time zone.
• /usr/app/base/bin/setsnmpconfig—Sets the host name, the IP address, the Ethernet IP address,
and the default router IP address. Also sets up trunk ports so that a complete configuration can
be downloaded from the NMS to a target LS2020 node.
Note These configuration scripts are intended for use only during the installation process.
When you runthese scripts from thecommand line, they behave very much asthey do inthe scripted
configuration procedure. However, one difference of note is that the setsnmpconfig command
checks for the presence of configuration files. (Normally, these files are not present during a typical
installation of a new LS2020 switch). If the system finds such files, it asks if you want to continue,
as shown below:
Configuration information already exists. If you continue, the configuration
information on this network node will be destroyed by overwriting the
following files:
/usr/app/base/config/configure.netdb
/usr/app/base/config/mma.db.dir
/usr/app/base/config/mma.db.pag
Continue? (y/n) [n]
Caution If you answer y (yes) to this query, the system overwrites the existing configuration files
for this particular LS2020 node, effectively deleting the files.
If configuration files are present and you choose not to overwrite them, the setsnmpconfig script
cannot continue. Instead, the script exits and returns you to the command line.
If configuration filesarenot present,oriftheyare present andyou choose to overwrite them, ascript
prompts you to enter network configuration information, as outlined in the following section,
“Entering Configuration Data.”
Entering Configuration Data
In this procedure, a script prompts you to enter basic LS2020 configuration information. In
performing this procedure, it is assumed that you have already initiated the boot sequence, as
previously described in the section “Connecting the Terminal to the NP.”
Note If a problem occurs with the LS2020 hard disk or the platform software, an error message is
displayed in lieu of the system output shown in Step 1 below. In this case, refer to the LightStream
2020 Network Operations Guide for instructions about reloading the LS2020 platform software.
Step 1 Observe the system’s boot display:
