CAUTION!
When you change an AP into an SM, any connections to SMs off that AP are
lost. Therefore, you should ensure you are connected to the AP through its
Ethernet side (not RF side) before changing it into an SM.
For example, if you are connected to an AP through one of its SMs and
mistakenly change the AP into an SM, you will lose connectivity and will need to
gain access to the Ethernet side of the AP through another part of your network
to change it back into an AP.
To transform a VLAN-disabled AP into an SM for spectrum analysis and then return the device to
an AP, perform the following steps.
Procedure 31: Using the Spectrum Analyzer in AP feature, VLAN disabled
1. Connect to the wired Ethernet interface of the AP.
2. Access the General tab of the Configuration page in the AP.
3. Set the Device Setting parameter to SM.
4. Click the Save Changes button.
5. Click the Reboot button.
6. When the module has rebooted as an SM, click the Tools navigation link on the
left side of the Home page.
7. Click the Spectrum Analyzer tab.
NOTE: If you simply click the Enable button on the Spectrum Analyzer tab, the
display may include fewer than all frequencies that are detectable, especially in a
band, such as 5.4 GHz, where the number of available center channels is great.
If you then click the Enable button a second time or set the
Webpage Auto Update parameter in the Configuration => General tab to a few
seconds, the display includes the entire spectrum. You can later reset
Webpage Auto Update to 0, to disable refresh.
8. Either set the Webpage Auto Update parameter in the Configuration => General
tab to a few seconds or repeatedly click the Enable button.
RESULT: The module enters the scan mode.
9. When you are finished analyzing the spectrum, click the Disable button.
10. In the left-side navigation links, click Configuration.
11. Click the General tab.
12. Set the Device Setting parameter to AP.
13. Click the Save Changes button.
14. Click the Reboot button.
RESULT: The AP boots with its previous frequency setting.
If you reboot an AP that has a configured Management VID parameter and Device Type
parameter set to SM, you are automatically removing the AP from the Management VLAN. The
following procedure enables you to successfully analyze the spectrum and return to management
via the VLAN feature. In many cases, it is advisable to use this procedure to
