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 display aaa
command to ensure that
the authentication rules
on the WX switch allow
the client to authenticate.
(See “Displaying the AAA
Configuration” on
page 507.)
2 Check the authorization
rules in the switch’s local
database (display 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 WX
switches in the Mobility
Domain. (See “Assigning
Authorization Attributes”
on page 487.)
„
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 display 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.
Configuration
information
disappears after a
software reload. The configuration changes
were not saved. 1 Retype the commands for
the missing configuration
information.
2 Type the save config
command to save the
changes.
