System information

1.6. Verify the Configuration
1. From a wireless client, verify that you can see the “Guest Network” SSID.
2. Using a wireless client, connect to the “Guest Network”.
3. Check the IP address that the switch DHCP server assigned.
4. Try pinging from a client on the Guest Network to the switch or AP IP address. The ping
should pass. Try web browsing to the switch IP address. The browse should fail because of
the ACL.
1.7. Feature Tests
This section has some recommend tests you can perform to demonstrate some of the Unified
Access System features. Note that the images in this section show IP address and other
configuration information that is different than the configuration used in Scenario 1. These
images are provide for reference and are not intended to be an exact match of what you see on
your switch.
1.7.1. L2 Start Roaming Test
Try roaming between the two APs (you can simulate this by disconnecting an AP from the switch
port that you are currently associated with assuming you are utilizing PoE to power the AP).
Check the associated client statistics to see which AP the client associates with and to observe
that the client has roamed to be associated with the other AP. If you start a Ping between the
client and the Unified Switch, you will also observe minimal packet loss during a roam.
1.7.2. Auto channel adjustment after associating with AP2
To check the current operating channel and to see if any channel adjustment is required, select the
WLAN tab from the navigation panel and traverse down to Monitoring Æ Access Points Æ
Managed Access Points.
When an AP is powered up, the Initial Channel Selection (ICS) algorithm is used to select the
best operating channel. The algorithm scans all the available channels (based on the country code)
by counting the number of packets received on each channel and selects the channel with the
lowest packet count.
A second algorithm, Auto Channel Adjustment (ACA) is used to periodically evaluate the
operating channel. The radio must be configured for Auto Channel Adjustment. This can be done
by selecting the Automatic Channel check box in the Radio tab of the Basic Setup page. By
default this parameter is enabled.
Note: Any changes made to the profile configuration must be explicitly applied to the AP. To
apply the profile, navigate to Administration Æ Advanced Configuration Æ AP Profiles,
select the profile to apply, and click Apply. This will temporarily disable the radios as the new
configuration is applied to the access points that use the profile. In other words, you can make
and submit one or many changes to an AP profile however these configuration modifications will
not be applied to the AP until you manually apply the profile or an AP comes online into
managed state after the profile changes are submitted.
