Add an ESS with the Web UI

5. In the Primary Radius Accounting Server list, select either the name of a

previously configured Radius accounting server profile or the No RADIUS option.

Selecting the No RADIUS option means that no Radius accounting messages will

be sent for clients connecting to this ESSID profile. For more information, see the

authentication chapter Radius Accounting for Clients.

6. In the Secondary Radius Accounting Server list, select the name of a previously

configured Radius accounting server profile or the No RADIUS option. If No Radius

is selected, then no Radius accounting messages will be sent for clients

connecting to this ESSID profile. For more information, see the security chapter

Radius Accounting for Clients.

7. In the Accounting Interim Interval field, type the time (in seconds) that elapses

between accounting information updates for Radius authentication. If a Radius

accounting server is enabled, the controller sends an interim accounting record

to the Radius server at the interval specified. Accounting records are only sent to

the Radius server for clients that authenticate using 802.1x. The interval can be

from 600 through 36,000 seconds (10 minutes through 10 hours). The default

value is 3,600 seconds (1 hour). For more information, see the security chapter

Radius Accounting for Clients.

8. Beacon Interval sets the rate at which beacons are transmitted. Setting the

beacon interval to a higher value decreases the frequency of unicasts and

broadcasts sent by the access point. If the power-save feature is enabled on

clients that are connected to access points, clients “wake up” less if fewer

unicasts and broadcasts are sent, which conserves the battery life for the clients.

In the Beacon Interval field, type the interval (in ms) at which beacons are

transmitted. The beacon interval must be between 20 through 1000 milliseconds.

For AP300/AP400 and AP1000, beacon interval is a multiple of 20, from 20 to

1000ms. For AP150 and OAP180, the beacon interval is a multiple of 100, from 100

to 500ms. If your WLAN consists mostly of Wi-Fi phones, and you have a low

number of ESSIDs configured (for example, one or two), Meru Networks

recommends setting the beacon interval to 100.

9. In the SSID Broadcast list, select one of the following:

— On: SSID is included in the beacons transmitted.

— Off: SSID is not included in the beacons transmitted. Also Probe Responses will

are not sent in response to Probe Requests that do not specify an SSID.

10. In the Bridging area, check any of these bridging options:

— AirFortress: FortressTech Layer 2 bridging and encryption with Fortress

Technology AirFortress gateway.

— IPv6: Configures bridging Internet version 6 addresses. IPv6 via tunneling mode

has these limitations:

No dynamic VLAN

No multiple ESSID mapping to same VLAN

No support for IPv6 filtering

No IPv6 IGMP snooping

— AppleTalk: configures bridging to AppleTalk networks on this ESS.

11. By default, access points that join the ESS profile and have the same channel form

a Virtual Cell. In the New APs Join ESS profile list, select one of the following:
