Create a network policy for these settings.
Use this task to set data collection and monitoring options:
- Application Visibility and
Control (AVC): AVC gives you information that can help you
manage network traffic and applications. AVC detects the application-layer
contents of the frame to determine the application or protocol that is
transmitting the data. ExtremeCloud IQ can then track the amount of data being
transmitted by a particular application or protocol.
- Device Wireless Activity Thresholds: Set activity
threshold limits above which event alarms are generated.
- Client Wireless Activity Thresholds: These alarms
identify when violations occur that affect the wireless health of a client as
reported in SLA reports for non-compliant clients. To trigger more alarms, lower
thresholds. To reduce the number of alarms, increase thresholds.
- Kernel Diagnostic Data Recorder (KDDR): KDDR logs capture
run-time statistical data about unexpected events for Extreme Networks devices.
Extreme Networks Support analyzes the content of these binary log files for
troubleshooting.
- Automatic Synthetic Traffic
Generation: Some of the Client 360, Device 360 and Network 360
monitoring capabilities require synthetic traffic generation.
-
Toggle Application Visibility and
Control
On to
detect frame application-layer contents.
-
Toggle Statistics
Collection
On to
record wireless activity statistics between the device and connected
clients.
You can also change the data
collection interval.
-
For Device Wireless Activity Thresholds, set the
following:
- CRC error rate
exceeds: The point at which the percent of CRC errors in
received wireless frames during the collection interval is considered to
be excessive.
- Tx drop rate
exceeds: The point at which the percent of transmitted
wireless unicast frames that a device drops during the collection
interval is considered excessive. A transmitted wireless frame is
dropped when the device tries to transmit the same unicast frame a
maximum number of times without receiving an acknowledgment from the
intended recipient.
- Rx drop rate
exceeds: The point at which the percent of dropped
wireless frames during collection interval is considered excessive. A
device might drop wireless frames on its ingress Wi-Fi interface for
several reasons, such as the arrival of duplicate frames or frames that
cannot be decrypted.
- Tx retry rate
exceeds: The point at which the percent of retransmitted
wireless frames during the collection interval is considered excessive.
A device tries to resend a unicast frame if the first effort does not
elicit an acknowledgment from its intended recipient.
- Airtime Consumption
exceeds: The point at which the percent of transmitted
and received airtime usage for a wireless interface during the
collection interval exceeds the maximum airtime consumption threshold.
-
For Client Wireless Activity Thresholds, set the
following:
Tx drop rate exceeds: Indicates the point at which the
percent of wireless unicast frames that a device drops during transmission
to the same client during the statistics collection interval is considered
excessive.
Rx drop rate exceeds: Indicates the point at which the
percent of dropped wireless frames received from the same client during the
statistics collection interval is considered excessive.
Tx retry rate
exceeds: Indicates the point at which the percent of
retransmitted wireless frames to the same client during the collection
interval is considered excessive.
Airtime Consumption
exceeds: Indicates the point at which the percent of airtime
that a device consumes while transmitting traffic to and receiving traffic
from the same client during the collection interval is considered excessive.
-
Toggle Kernel Diagnostic Data
Recorder
On to
capture run-time statistical data about unexpected events.
-
For Automatic Synthetic Traffic Generation:
-
Enable RADIUS Authentication to create synthetic traffic.
-
Turn Check Radius service
connectivity via Status-Server
On to check RADIUS service connectivity.
Make sure Status-Server is enabled on the RADIUS server.
-
Adjust the check Interval if necessary.
