MSM7xx Controllers Configuration Guide v6.4.0

The tab title displays the following information:
• Online: Indicates the number of APs that are able to exchange management information with
the controller.
• Offline: Indicates the number of APs that have stopped sending management information to
the controller. Rediscovery may re-establish the connection. If not, the APs may have lost power
or a network failure has occurred. The APs will have a diagnostic value of Not responding
on the Controller >> Controlled APs > Discovered APs page. APs that are flagged as Admin
Down do not appear in this count.
• Admin Down: Indicates the number of APs that are Offline and have been manually set to
Admin Down (Administratively Down) by an administrator. This state is used to flag an AP
that is known to be offline. For example, for maintenance or relocation.
Access Points per State - Current
Displays the number of access points that are currently in each of the following states: Online,
Offline, Admin Down.
Access Points per State - Last 24 Hours
Displays the number of APs that have been online or offline for each hour during the last 24 hours.
To be counted as online, an AP must be online for at least 30 minutes of an hour.
Access Points per Model
Displays the number of access points of each model.
Access Points with Most Severe Interferences - Last 24 Hours
Displays the ten access points that detected the most instances of severe interference over the last
24 hours.
Severe Interferences - Last 24 Hours
Displays the number of severe interferences detected by all access points for each hour during the
last 24 hours.
Access Points with Most Retry Frames - Last 24 Hours
Displays the ten access points that executed the most retry frames (single and multiple) over the
last 24 hours.
Retry Frames Rate - Last 24 Hours
Displays the total number of single and multiple retry frames for all access points for each hour
during the last 24 hours.
• Single retry: Displays the number of MSDUs successfully transmitted after one (and only one)
retransmission (on the total of all associated fragments). This may be due to collisions, noise,
or interference. Large numbers of single retries can indicate that too many computers are using
the wireless network or that something is interfering with transmissions.
• Multiple retries: Displays the number of MSDUs successfully transmitted after more than one
retransmission (on the total of all associated fragments). This may be due to collisions, noise,
or interference. Excessive retries can indicate that too many computers are using the wireless
network or that something is interfering with transmissions.
