To configure the default AP settings:
1 From the main menu, click Altitude APs . The Altitude APs screen is displayed.
2 In the left pane, click AP Default Settings .
3
Modify the following AP default settings as required:
●
AP Properties
●
Radio Settings
●
Static Configuration
●
Dynamic Radio Management
●
WM-AD Assignments
4
In the AP Properties section, modify the following:
●
Poll Timeout * Interval – Type the timeout and interval values, in seconds, for polling the
controller. The default values are 10 seconds and 2 seconds, respectively.
●
Telnet Access – Select whether Telnet Access to the Wireless AP is enabled or disabled.
● Maintain client sessions
– Select whether the AP should remain active if a link loss with the
controller occurs. This option is enabled by default.
●
Restart service without controller – Select whether the AP should provide service to the client
devices when it can not connect to the controller for initial configuration upon reboot.
●
Broadcast for disassoc . – Select if you want the Wireless AP to use broadcast disassociation when
disconnecting all clients, instead of disassociating each client one by one. This will affect the
behavior of the AP under the following conditions:
■
If the Wireless AP is preparing to reboot or to enter one of the special modes (DRM initial
channel selection).
■
If a BSSID is deactivated or removed on the Wireless AP.
This option is enabled by default.
● Country
– Select the country of operation. This option is only available with some licenses.
5 In the Radio Settings section, modify the following:
●
Enable Radio – Select the radios you want to enable.
● DTIM * Beacon Period
– For each radio, type the desired DTIM (Delivery Traffic Indication
Message) period—the number of beacon intervals between two DTIM beacons. To ensure the best
client power savings, use a large number. For example, 5. Use a small number for broadcast and
multicast delay. The default value is
1
.
●
RTS/CTS * Frag. Threshold – For each radio, type the packet size threshold, in bytes, above
which the packet will be preceded by an RTS/CTS (Request to Send/Clear to Send) handshake.
The default value is
2346 , which means all packets are sent without RTS/CTS. Reduce this value
only if necessary. Also, type the fragment size threshold, in bytes, above which the packets will
be fragmented by the AP prior to transmission. The default value is
2346 , which means all
packets are sent unfragmented. Reduce this value only if necessary.
●
Channel – For each radio, select the wireless channel that the Wireless AP will use to
communicate with wireless devices. Depending on the regulatory domain (based on country),
some channels may be restricted. The default value is based on North America. The
Auto
selection allows the Wireless AP to select the appropriate channel automatically. For more
information, see
Appendix B, “Regulatory Information.”
If DRM is enabled (DRM is enabled by default), it scans automatically for a channel, using a
channel selection algorithm. For more information, see
“Configuring Dynamic Radio
Management” on page 77 .
