Troubleshooting; Fixing Common Setup Problems - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

Some common problems that occur during switch installation and basic configuration are simple to
solve. However, to "recover" the system password, you must delete the existing switch configuration.
System logs provide a history of MSS events. Traces display real-time messages from all MSS areas.
Some show commands are particularly useful in troubleshooting. The show tech-support command
combines a number of show commands into one, and provides an extensive snapshot of your switch
configuration settings for D-Link Technical Support.

Troubleshooting

Diagnosis
The switch's time and date are
currently incorrect, or were incorrect
when you generated the self-signed
certificate or certificate request.
The country code might not be set or
might be set for another country.
The configuration changes were not
saved.
The switch was unable to load the
system image file.
Remedy
1. Use set timezone to set the time zone in
which you are operating the switch. (See
"Setting the Time Zone".)
2. Use set timedate to configure the current
time and date in that time zone. (See
"Statically Configuring the System Time
and Date".)
3. Reconfigure the administrative certificate(s).
(See "Managing Keys and Certificates,".)
4. If you have already configured a certificate
on the switch for authentication by network
users, you must recreate this certificate,
too.
1. Type the show system command to
display the country code configured on
the switch.
2. If the value in the System Countrycode
field is NONE or is for a country other than
the one in which you are operating the
switch, use the set system countrycode
command to configure the correct country
code. (See "Specifying the Country of
Operation".)
1. Retype the commands for the missing
configuration information.
2. Type the save config command to save
the changes.
Type the boot command at the boot prompt.
