Table of Contents
The Wireless tab is very similar to the Charts tab, however it displays charts only for devices that have sFlowTrend-Pro has identified as 802.11 wireless access points. The Wireless tab includes charts that display 802.11 specific data in addition to the basic charts available in the Charts tab.
This tab includes a control bar that allows you to select the wireless access point (WAP) and radio for which you would like to analyse and view traffic data, and the type of chart to display.
The Wireless tab includes the same time selection, filtering, and chart interaction features as the Charts tab, see Chapter 3, Charts for details.
To view data on network traffic flowing through a specific WAP, use the WAP selector in the control bar to select the WAP that you are interested in. The WAP selector lists only the devices that have been identified by sFlowTrend-Pro to have 802.11 radios. sFlowTrend-Pro identifies 802.11 radios from the ifType information exported by sFlow. A WAP is listed using its SNMP IP address, sFlow agent address, DNS Name or sysName (see Section 7.2.1, “Setting the switch and interface naming policy”).
WAPs shown in italics in the selection list are disabled, meaning that data is not being stored for these switches (see Section 7.1, “Configuring switches in sFlowTrend-Pro” for information on enabling and disabling switches and WAPs). Changing the WAP selection causes a chart for the newly selected WAP to be displayed.
To view data on network traffic flowing through a specific radio, use the Radio selector in the control bar to select the radio that you are interested in. The Radio selector lists the radios for the currently selected WAP, for which sFlow data is being received and stored. A radio is listed using its ifIndex, ifDescr, IfName, or ifAlias. (see Section 7.2.1, “Setting the switch and interface naming policy”). Changing the radio selection causes a chart for the newly selected radio to be displayed.
The Radio selector also contains an option All. Selecting this option allows you to view traffic flows through the whole device (across all interfaces and radio ports). This option is not available if the current chart selection is set to WAP frame counters, WAP control frame counters, WAP error counters, WAP associated stations, WAP QoS counters, Counters or Utilization, since these charts can only display data for a single interface.
