| Field | Description |
|---|---|
| Poll Timeout | Type the timeout value, in seconds. The AP uses
this value to trigger re-establishing the link with the Controller if
the AP does not get an answer to its polling. The default value is 10
seconds. Note: If you are configuring session
availability, the Poll Timeout value should be 1.5 to 2 times of
Detect link failure value on AP Properties screen. For more
information, see Session Availability.
|
| Secure Tunnel | This feature, when enabled, provides encryption,
authentication, and key management between the AP and/or controllers. Select the desired Secure Tunnel mode from the drop-down list:
Note: Changing a Secure Tunnel mode will
automatically disconnect and reconnect the AP.
|
| Secure Tunnel Lifetime | Available when Secure Tunnel is enabled. Enter an
interval (in hours) at which time the keys of the IPSEC tunnel are
renegotiated. Note: Changing the Secure Tunnel
Lifetime setting will not cause any AP disruption.
|
| Enable SSH Access | Click to enable or disable SSH for access to the AP. |
| Enable location-based-service | Enable or disable the AeroScout, Ekahau, or Centrak location-based service for the AP. |
| Maintain client session in event of poll failure | Select this option (if using a bridged at AP VNS) if the AP should remain active if a link loss with the controller occurs. This option is enabled by default. |
| Restart service in the absence of controller | Select this option (if using a bridged at AP VNS) to ensure the AP‘s radios continue providing service if the AP‘s connection to the controller is lost. If this option is enabled, it allows the AP to start a bridged at AP VNS even in the absence of a controller. |
| Use broadcast for disassociation | Select this option if you want the AP to use
broadcast disassociation when disconnecting all clients, instead of
disassociating each client one by one. This affects the behavior of the
AP under the following conditions:
This option is disabled by default. |
| Enable LLDP | Click to enable or disable the AP from
broadcasting LLDP information. This option is disabled by default. If SNMP is enabled on the controller and you enable LLDP, the LLDP Confirmation dialog is displayed. Select one of the following:
|
| Announcement Interval | If LLDP is enabled, type how often the AP
advertises its information by sending a new LLDP packet. This value is
measured in seconds. If there are no changes to the AP configuration that impact the LLDP information, the AP sends a new LLDP packet according to this schedule. Note: The Time
to Live value cannot be directly edited. The Time to Live value is
calculated as four times the Announcement Interval
value.
|
| Announcement Delay | If LLDP is enabled, type the announcement delay. This value is measured in seconds. If a change to the AP configuration occurs which impacts the LLDP information, the AP sends an updated LLDP packet. The announcement delay is the length of time that delays the new packet delivery. The announcement delay helps minimize LLDP packet traffic. |
| IP Multicast Assembly | Click to Enable or Disable IP Multicast Assembly on this Wireless AP. If Enabled, the IP Multicast Assembly feature assembles multicast data packets that were too large to fit the MTU size of the tunnel and were fragmented in order to fit the tunnel header. This feature is disabled by default. |
| Balanced Channel List Power | This simplifies power settings such that they will function across all channels in the channel plan. |
| Low Power Mode Override | Check this box to have AP ALWAYS operate in
4x4 mode regardless what was negotiated with the Switch PoE4). When this option is
cleared, the AP operates in 2x2 or 4x4 depending on what was negotiated with the
Switch Poe using the 2-event classification.
The default configuration for the 39xx AP is disabled. |
| LED | Select the desired LED pattern from the drop-down list. Options include: Off, WDS Signal Strength, Identify, and Normal. |
| Real Capture | Click Start to start real
capture server on the AP. Default capture server timeout is set to 300
seconds and the maximum configurable timeout is 1 hour. While the
capture session is active, the AP interface operates in promiscuous
mode. From the Wireshark GUI, set the capture interface to the IP address of the selected AP, and select null authentication. Once Wireshark connects to the AP, the AP's interfaces are listed as available to capture traffic. eth0 is the wired interface, wlan0 is the 5Ghz interface, and wlan1 is the 2.4Ghz interface. You can capture bidirectional traffic on eth0, wifi0, and wifi1. The capture on wifi0 and wifi1 does not include internally generated hardware packets by the capturing AP. The capturing AP does not report its own Beacons, Retransmission, Ack and 11n Block Ack. If this information is needed, perform Real Capture from a second AP that is close by. Make sure both APs are on the same wireless channel. Broadcast an SSID to activate the radios, but do not broadcast the SSID of the AP you are troubleshooting. You do not want the clients to connect to the second capturing AP. Capture statistics are found on the Active Wireless APs report (see Viewing Statistics for APs). |
