or

Use this parameter to display information that meets either or two criteria, such as a specified ESSIDExtended Service Set Identifier. ESSID refers to the ID used for identifying an extended service set. or channel.

page <page>

Enter a number from 10–100 (inclusive) to specify the number of entries that should appear in each page of the output for this command.

If you selected a page value of 10, the output would appear in 10 pages with 10 entries.

sort <sort>

Sort the output by the specified data column.

start <start>

Start displaying the output at specific spectrum index value.

Usage Guidelines

Use this command to view channel and signal information for wireless clients seen by the spectrum monitor.

Examples

The example shows that the spectrum monitor ap999 sees eight different clients on channel 149. The output in the example below has been divided into two tables to better fit this document. In the ArubaOS CLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions., the output appears as a single, long table.

The output of this command includes the following information:

Column

Description

mac

MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the client.

bssid

Basic Service Set Identifier for a client. This is usually the device’s MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address.

essid

Extended service set identifier that names a wireless network.

spectrum-id

Identifier assigned to the client by the spectrum monitor.

chan

Radio channel used by the BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly..

phy-type

Radio phy type. Possible types include:

802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps.

signal(dBm)

Client signal strength, in dBmDecibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors..

add-time

Time when the client was first detected by the spectrum monitor.

last-seen

Time when the spectrum monitor last detected that the client was active.

Description

ap spectrum local-override

Converts an AP or AMAir Monitor. AM is a mode of operation supported on wireless APs. When an AP operates in the Air Monitor mode, it enhances the wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more. However, clients cannot connect to APs operating in the AM mode. into a spectrum monitor by adding it to the spectrum local-override list.

rf dot11g-radio-profilemodespectrum-mode

Sets an 802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network. radio so that the device operates as a spectrum monitor, and can send spectrum analysis data to a desktop or laptop client.
