3com WX1200 3CRWX120695A Manuel D’Utilisation

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.

Mgmt LED is quickly 
blinking amber.

CLI stops at boot 
prompt (

boot>).

The WX switch was unable to 
load the system image file.

Type the boot command at 
the boot prompt.
