Wireless Network Management
Monitoring the Wireless Network
■ WLAN—This column displays the index number of the WLAN to which the
station has connected (not the service set identifier [SSID]). The WLAN
defines the broadcast group for the station and determines settings such
as encryption and QoS.
■ VLAN—The virtual LAN (VLAN), or subnet, in which the module will
forward traffic from this station is displayed. This important setting
determines the type of network access that the station receives. If the
module implements user-based VLANs in this WLAN, you should verify
that the station has received the correct VLAN assignment.
■ Radio Index—The radio to which the station connects is also listed. If you
see an unauthorized station, this information will point you toward the
intruder’s physical location.
■ Radio Type—This setting indicates the 802.11 mode in which the station
and the RP radio to which it connects operate.
You should be able to interpret this information to monitor and troubleshoot
your wireless network.
For example, the user of the wireless station listed in Figure 6-1 has reported
that he cannot connect to the network. The administrator views the Network
Setup > Wireless Stations screen. From the green check mark in the Ready
column, she sees that the station has actually connected to the WLAN: it
should be able to send and receive traffic. However, the station has not
received an IP address, so the user is not able to access any resources. The
administrator could then check the station’s VLAN assignment or trouble-
shoot Dynamic Host Configuration Protocol (DHCP) forwarding on the wire-
less services-enabled switch.
You can also save information about one or more wireless stations to a comma-
separated file on your workstation. Select the stations and click Export.
Disconnecting a Wireless Station
If, in the Device Information > Wireless Stations screen, you see a wireless
station that should not connect to your network, you can immediately disas-
sociate it.
Select the station and click the Disconnect button. Note that the station can
immediately reassociate unless you take steps to prevent it. For example, first
change a preshared key that has been compromised, then disconnect all
unauthorized stations.
