Wireless Local Area Networks (WLANs)
Configuration Options: Normal Versus Advanced Mode
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. However,
because such precise control adds unnecessary complexity in most environ-
ments, this mode is not generally recommended.
In advanced mode configuration, the Wireless Edge Services xl Module sup-
ports up to 32 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.
