Wireless Local Area Networks (WLANs)

Table 4-1. WLAN Assignment to BSSID
When deciding which WLAN index number to use for a WLAN, keep in mind that
this number determines on which BSSID RPs carry that WLAN’s traffic. You should
generally avoid mixing bulk data and time-sensitive data such as voice on the same
BSSID. For example, if stations connect to WLAN 1 to download files from your
network’s FTP server, you should not configure WLAN 5 for VoWLAN devices.
Advanced Mode Configuration
In advanced mode, you manually control which RP radios support which WLANs.
You can even control to which BSSID a WLAN’s SSID is assigned, and which of
multiple SSIDs that share a BSSID is present in beacons (is the primary WLAN).
However, because such precise control adds unnecessary complexity in most envi-
ronments, this mode is not generally recommended.
In advanced mode configuration, the Wireless Edge Services zl Module supports up
to 256 WLANs.
Note Remember that advanced mode can lead to configuration errors that cut off network
access for some users to some WLANs.
Whenever you prevent certain RPs or radios from supporting a WLAN, whether
deliberately or not, you open the possibility that roaming wireless stations lose their
connection to the network—which can be frustrating.
In addition, because you must manually assign WLANs to radios, advanced mode
configuration can be tedious.
