Wireless Interface Configuration - Details

The following table lists the additional wireless interface information you can review:

AP ID	Unique AP numeric identifier up to 9999 characters long
AP Name	Alphanumeric string up to 64 characters long assigned as identifier for the access point
AP Model	Model type of AP
Interface Description	Description can be up to 256 alphanumeric characters long and contain spaces (for example, Lobby AP interface 1). By default, the description is ieee80211-ap_id-index_ID.
Administrative Status	Indicates whether the interface is to be used: Up means enable the interface, Down means disable the interface.
Operational Status	Indicates whether the interface is operational (enabled) or disabled
Last Change Time	Time of last operational stat change of the wireless interface
Radio Type	Indicates the radio support: RF3 - 11a/b/g (in AP150, OAP180) RF6 - 11a/b/g/n (AP300 and AP1000 series)
MTU (bytes)	Maximum transfer unit value for the Ethernet interface - can be 1 to 65536 bytes
Channel	The channel numbers displayed depend on the RF Band Selection and the regulatory domain for each country; for example, in the United States 802.11b shows channels 1 through 11 and 802.11a shows channels 36, 40, 44, etc. Two access points can belong to the same virtual AP only if they are on the same channel. Thus, two neighboring access points on different channels cannot perform seamless handoff (0 ms).
Operating Channel	Channel being used, for example 1.
Short Preamble	Short preambles are more efficient on the air, but not all clients support them. This setting can be On or Off.
RF Band Support	Supported RF band, such as 802.11abgn
RF Band Selection	Information here is based on both the AP model and radio cards installed (for example, 802.11an) and the licensing in effect
Antenna Selection	Not used in release 4.1
Transmit Power High (dBm)	Meru AP radios operate at their maximum power level by default. High power level increases the signal strength of the frames received by the client stations, allowing a client station to decode frames at a higher rate and increasing the coverage area. This causes minimal interference because Meru uses Virtual Cell technology, moving clients to a better AP without re-association. For a very few cases, we recommend that you reduce the power level on APs due to co-channel-interference. Check with Support first to make sure your issue really is due to co-channel-interference. The maximum level depends on the country code and the RF band in use.
AP Mode	Normal Mode (servicing clients first and scanning in the background) or Scanning Mode (dedicated monitoring for Rogue APs)
Scanning channels	Indicates which channels are being scanned, for example 1
Protection Mechanism	Not used in release 4.1
Protection Mode	Configures 802.11b/g interoperability mode. This setting defaults to auto and should not be changed without consulting Meru Support.
Number of Antennas	Indicates the number of active antennas for the access point
Dual abg Support	Indicates whether dual abg support is on or off
Channel Width	20 MHz , 40MHz Extension Channel Above, 40MHz Extension Channel Below Note that all APs in a Virtual Cell must have the same channel width.
MIMO Mode	2x2 for either AP1000 or AP300 with an 802.3af PoE; 3x3 for AP300 depending on radio and power source configuration
802.11n only mode	802.11n only mode is for AP300/AP1000s with N capability. On: Supports only 802.11n Off: (default) supports 802.11an or 802.1bgn
Virtual Cell	Virtual Cell Mode enables Virtual Cell for AP300 only. On: Virtual Cell on for AP300 Off: Virtual Cell off for AP300
