What is off-channel scanning defer?
What is off-channel scanning defer?
As long as there is detected platinum traffic, there is implemented scan defer time (100ms-60sec). In this example, it means the scan will be delayed for configurable period of time of 100msecs.
How do I turn off RRM?
If you want do disable RRM you can select “off” option. By default it is “auto”. If you select static configuration option (ie Leader option) you can add members into RF group as shown in the below.
What is Off-channel?
Off-channel scanning is when a Wi-Fi client device tunes its radio to another channel to look for available APs or scans for APs on a channel to which it is not connected (hence “off-channel”).
What is APs channel?
An access point (AP) can also perform off-channel scanning. This process is the same as off-channel scanning for Wi-Fi client devices and essentially allows the AP to tune its radio to a different channel for a finite amount of time.
What is AP scan?
A positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses a special dye containing radioactive tracers. These tracers are either swallowed, inhaled, or injected into a vein in your arm depending on what part of the body is being examined.
What is access point scanning?
Wireless scanning technologies work by building an initial database of access points in the environment, including IP and MAC addresses. As a scan runs, it identifies, compares, and flags access points that don’t coordinate with the master list.
What are three options of RRM?
RRM enables controller to monitor their associated AP for the following information.
- Traffic Load (how many clients in a given AP)
- Interference (coming from other 802.11 soruces)
- NOise (non-802.11 that interfere with current CH)
- Coverage (RSSI & SNR for all connected CH)
- Other APs (number of nearby AP)
What is RRM WiFi?
Auto Radio Resource Management (RRM) uses WiFi radio statistics from each access point in a network location to calculate the best channel and best transmit power for the access point. Auto RRM is sometimes called Smart WiFi. You can turn Auto RRM on and off for each network location independently.
What is off channel habitat?
Off-channel habitats (OCH) are those bodies of water adjacent to the main channel that have surface water connections to the main river channel at summer discharge levels.
What is scan SSID?
Here’s a brief overview of some of the most important information that you can obtain with the help of a free WiFi scanner app like NetSpot: Service Set Identifier (SSID): In simple terms, an SSID is the name of a WiFi network. It’s what you see when you want to select a WiFi network to log in a new device.
What channel is best for 2.4 GHz?
The recommended channels to use on 2.4 Ghz are Channel 1, 6 & 11. As can be seen in the above diagram, these channels do not overlap into each other. In general 2.4 Ghz should be considered a legacy band for older devices that do not support 5 Ghz. It is often more crowded and less performant than 5 Ghz.
How many channels are there in 2.4 GHz?
The 2.4GHz band is broken up into 11 channels (1-11), each 20MHz wide.
What is off-channel scanning defer and how does it work?
By default, Off-Channel Scanning Defer is enabled for user priorities 4, 5 and 6, with a defer-time of 100 milliseconds. Thus, if there is a voice call active (which typically uses a U ser Priority ( UP) of 6 with a sample duration of 20 milliseconds), this will prevent the AP radio from going offchannel.
What is off-channel scanning for Wi-Fi client devices?
What is off-channel scanning for Wi-Fi client devices? Off-channel scanning is when a Wi-Fi client device tunes its radio to another channel to look for available APs or scans for APs on a channel to which it is not connected (hence “off-channel”).
Does off-channel scanning affect packet delivery?
However, while the APs are performing off-channel scanning (typically, for 80 millisecond periods every 3 to 20 seconds), they cannot service clients on the channel they are serving. This will result in minor, intermittent delays or loss in packet delivery (from 0.05% to as much as 1.5% packet loss).
Should I enable or disable ble Beacon interference detection?
On an AP that supports CleanAir (such as 2700 or 2800 series), if BLE Beacon Interference Detection is enabled, then the 2.4GHz radio will perform off-channel scanning (even if RRM Off-Channel is disabled). So, disable this feature, if the application requires that the 2.4GHz radio never go off-channel.
