Symptom
Diagnosis
Remedy
Client cannot access the
network.
This symptom has more than one possible
cause:
• The client might be failing authentication or
might not be authorized for a VLAN.
1. Type the show aaa command to ensure
that the authentication rules on the switch
allow the client to authenticate. (See
“Displaying the AAA Configuration”.)
2. Check the authorization rules in the
switch’s local database (show aaa) or on
the RADIUS servers to ensure the client is
authorized to join a VLAN that is configured
on at least one of the switches in your
network. (See “Assigning Authorization
Attributes”.)
• If the client and switch configurations are
correct, a VLAN might be disconnected. A
client connected to a disconnected VLAN is
unable to access the network.
1. Type the show vlan config command to
check the status of each VLAN.
2. If a VLAN is disconnected (VLAN state is
Down), check the network cables for the
VLAN’s ports. At least one of the ports in
a VLAN must have a physical link to the
network for the VLAN to be connected.
Recovering the System When the Enable
Password is Lost
To recover a DWS-1008 switch, use the following procedure.
Caution: Recovering the system will delete your configuration file.
1. Reboot the switch, and interrupt the switch boot process.
Insert a pin into the restart switch or power the switch off and on again to cause the switch
to reboot. The restart switch is located next to its serial console port.
2. When you see descending numbers on the console, press
q, then press Enter.
3. Type the following command at the
boot>
prompt:
boot>
boot OPT+=default
If you do not type the command before the reset cycle is complete, the switch returns to the state it
was in before you restarted it. Once you have entered the command, the switch returns to its initial
unconfigured state. For information on how to configure the switch, see “First-Time Configuration via
the Console”.
Caution: Use an enable password that you will remember. If you lose the password, the only way to
restore it causes the system to return to its default settings and wipes out the configuration.
