320656-A
Diagnosis
This symptom has more than one
possible cause:
• The client might be failing
authentication or might not be
authorized for a VLAN.
• If the client and switch
configurations are correct, a
VLAN might be disconnected.
A client connected to a VLAN
that is disconnected is unable to
access the network.
The configuration changes were not
saved.
The WSS was unable to load the
system image file.
Remedy
1. Type the show aaa command
to check the authentication
rules on the WSS, to ensure
that the client can be
authenticated.
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 WSSs in the Mobility
Domain.
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.
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.
