Table A-1 RoamAbout Switch Setup Problems and Remedies
Symptom Diagnosis Remedy
RoamAbout Switch
Manager or a web
browser (if you are
using Web View) warns
that the RoamAbout
Switch’s certificate date
is invalid.
The switch’s time and date
are currently incorrect, or
were incorrect when you
generated the self-signed
certificate or certificate
request.
1. Use set timezone to set the time zone in which
you are operating the switch. (See “Setting the
Time Zone” on page 5-20.)
2. Use set timedate to configure the current time
and date in that time zone. (See “Statically
Configuring the System Time and Date” on
page 5-22.)
3. Reconfigure the administrative certificate(s).
(See Chapter 16, 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.
RoamAbout Switch
does not accept
configuration
information for an AP or
a radio.
The country code might
not be set or might be set
for another country.
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” on page 9-22.)
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 theswitch allow the client
to authenticate. (See “Displaying the AAA
Configuration” on page 3-10.)
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
RoamAbout switches in the Mobility Domain.
(See “Assigning Authorization Attributes” on
page 17-42.)
• 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.
