Add an ESS with the Web UI

— Off: Disables multicasting.

16. Silent Client Polling is used with Virtual Cell to track wireless clients that roam

without transmitting (for example, phones and other devices that conserve

battery life). This feature is enabled by default. In the Silent Client Polling list,

select one of the following:

— On: (default) Tracking information is sent between the controller and APs, and

also sent between the APs and a phone that is not in a call or in powersave

mode. This feature keeps the system appraised of a client phone location if

the client moves between APs while the phone is inactive.

— Off: Disables silent client polling.

17. Virtual Cell (which includes Virtual Port) is on by default; this affects AP300,

AP400, and AP1000. On the AP1000, Virtual Cell is controlled exclusively by the

settings here. You can create any combination of Virtual Cell ESS profiles and

non-Virtual Cell ESS profile and use them on an AP1000 radio. For AP300s and

AP400s, this setting is not the only factor that affects Virtual Cell - the Dot11

radio interface setting for each radio also controls Virtual Cell on each AP. They

both must on for Virtual Cell to work. See When is Virtual Cell Really on for an AP?

for details.

To enable/disable Virtual Cell on this ESS, select one of the following:

— On: (default) Access points on the same channel share the same BSSID, forming

a Virtual Cell (default). Note that if an ESSID profile is configured for Virtual

Cell, but an AP300/AP400 radio interface providing that EESID service is

non-Virtual Cell, the service will be non-Virtual Cell on that radio interface.

Conversely, if an AP300/AP400 radio is configured for Virtual Cell, but either

the ESSID Virtual Cell setting is off or Virtual Port is off, no service will be

provided by that radio. The radio must have Virtual Cell on and the ESSID

profile must have both Virtual Cell and Virtual Port on for the service to be

Virtual Cell. See When is Virtual Cell Really on for an AP? for details.

— Off: Prevents APs on the same channel from sharing the same BSSID.

Caution!

Multicasting is allowed only when an ESS profile has a one-to-one mapping

with the default VLAN for this ESS profile. No other ESS profile can use the same VLAN

and security rules associated with this ESS profile must not redirect traffic to another

VLAN. Multicasting is an advanced feature. Enable multicasting only if you need to

use a multicast application. Enabling multicasting causes all multicast packets on the

air side to appear on the wired side, and all multicast packets on the wired side to

appear on the air side.

Note:

All APs on the same channel in a Virtual Cell must have the same setting for

these values:

 RF-Mode

 Channel Width

 N-only Mode
