Step 1 |
Configure the multicast
feature by following these steps:
-
Choose
.
-
Select or unselect the
Multicast Direct feature check box. The default
value is disabled.
Note
|
Enabling the multicast direct
feature does not automatically reset the existing client state. The wireless
clients must rejoin the multicast stream after enabling the multicast direct
feature on the controller.
|
-
In the
Session Message Config area, select
Session announcement State check box to enable the
session announcement mechanism. If the session announcement state is enabled,
clients are informed each time a controller is not able to serve the multicast
direct data to the client.
-
In the
Session announcement URL text box, enter the URL
where the client can find more information when an error occurs during the
multicast media stream transmission.
-
In the
Session announcement e-mail text box, enter the
e-mail address of the person who can be contacted.
-
In the
Session announcement Phone text box, enter the phone
number of the person who can be contacted.
-
In the
Session announcement Note text box, enter a reason
as to why a particular client cannot be served with a multicast media.
-
Click
Apply.
|
Step 2 |
Add a media stream by
following these steps:
-
Choose
to open the Media Stream page.
-
Click
Add New to configure a new media stream. The
Media Stream > New page appears.
Note
|
The Stream Name, Multicast
Destination Start IP Address (IPv4 or IPv6), and Multicast Destination End IP
Address (IPv4 or IPv6) text boxes are mandatory. You must enter information in
these text boxes.
|
-
In the
Stream Name text box, enter the media stream name.
The stream name can be up to 64 characters.
-
In the
Multicast Destination Start IP Address (IPv4 or
IPv6) text box, enter the start (IPv4 or IPv6) address of the
multicast media stream.
-
In the
Multicast Destination End IP Address (IPv4 or IPv6)
text box, enter the end (IPv4 or IPv6) address of the multicast media stream.
Note
|
Ensure
that the Multicast Destination Start and End IP addresses are of the same type,
that is both addresses should be of either IPv4 or IPv6 type.
|
-
In the
Maximum Expected Bandwidth text box, enter the
maximum expected bandwidth that you want to assign to the media stream. The
values can range between 1 to 35000 kbps.
Note
|
We recommend that you use a
template to add a media stream to the controller.
|
-
From the
Select from Predefined Templates drop-down list
under Resource Reservation Control (RRC) Parameters, choose one of the
following options to specify the details about the resource reservation
control:
-
Very Coarse (below 300 kbps)
-
Coarse (below 500 kbps)
-
Ordinary (below 750 kbps)
-
Low (below 1 Mbps)
-
Medium (below 3
Mbps)
-
High (below 5
Mbps)
Note
|
When you select a predefined
template from the drop-down list, the following text boxes under the Resource
Reservation Control (RRC) Parameters list their default values that are
assigned with the template.
|
-
Average Packet
Size (100-1500 bytes)—Specifies the average packet size. The value can be in
the range of 100 to 1500 bytes. The default value is 1200.
-
RRC Periodic
update—Enables the RRC (Resource Reservation Control Check) Periodic update. By
default, this option is enabled. RRC periodically updates the admission
decision on the admitted stream according to the correct channel load. As a
result, it may deny certain low priority admitted stream requests.
-
RRC Priority
(1-8)—Specifies the priority bit set in the media stream. The priority can be
any number between 1 and 8. The larger the value means the higher the priority
is. For example, a priority of 1 is the lowest value and a value of 8 is the
highest value. The default priority is 4. The low priority stream may be denied
in the RRC periodic update.
-
Traffic Profile
Violation—Specifies the action to perform in case of a violation after a
re-RRC. Choose an action from the drop-down list. The possible values are as
follows:
Drop—Specifies that a stream
is dropped on periodic revaluation.
Fallback—Specifies that a
stream is demoted to Best Effort class on periodic reevaluation.
The default value is
drop.
-
Click
Apply.
|
Step 3 |
Enable the media stream for
multicast-direct by following these steps:
-
Choose
WLANs > WLAN ID to open the WLANs > Edit page.
-
Click the
QoS tab and select Gold (Video) from the Quality of
Service (QoS) drop-down list.
-
Click
Apply.
|
Step 4 |
Set the EDCA parameters to
voice and video optimized (optional) by following these steps:
-
Choose Wireless > 802.11a/n or 802.11b/g/n > EDCA Parameters.
-
From the
EDCA Profile drop-down list, choose the Voice and
Video Optimized option.
-
Click
Apply.
|
Step 5 |
Enable the admission control
on a band for video (optional) by following these steps:
Note
|
Keep the voice bandwidth
allocation to a minimum for better performance.
|
-
Choose Wireless > 802.11a/n or 802.11b/g/n > Media to open the page.
-
Click the
Video tab.
-
Select the Admission Control (ACM) check box to enable static CAC for this radio band. The default value is disabled.
-
Click
Apply.
|
Step 6 |
Configure the video bandwidth
by following these steps:
Note
|
The template bandwidth that
is configured for a media stream should be more than the bandwidth for the
source media stream.
|
Note
|
The voice configuration is
optional. Keep the voice bandwidth allocation to a minimum for better
performance.
|
-
Disable
all WMM WLANs.
-
Choose Wireless > 802.11a/n or 802.11b/g/n > Media to open the page.
-
Click the
Video tab.
-
Select the
Admission Control (ACM) check box to enable the
video CAC for this radio band. The default value is disabled.
-
In the Max RF Bandwidth
field, enter the percentage of the maximum bandwidth allocated to clients for
video applications on this radio band. Once the client reaches the value
specified, the access point rejects new requests on this radio band.
-
The range is 5 to 85%.
-
The default value is 9%.
-
Click
Apply.
-
Reenable all WMM WLANs and
click
Apply.
|
Step 7 |
Configure the media
bandwidth by following these steps:
-
Choose Wireless > 802.11a/n or 802.11b/g/n > Media to open the 802.11a (or 802.11b) > Media > Parameters page.
-
Click the
Media tab to open the Media page.
-
Select the
Unicast Video Redirect check box to enable Unicast
Video Redirect. The default value is disabled.
-
In the
Maximum Media Bandwidth (0-85%) text box, enter the
percentage of the maximum bandwidth to be allocated for media applications on
this radio band. Once the client reaches a specified value, the access point
rejects new calls on this radio band.
-
The default value is 85%;
valid values are from 0% to 85%.
-
In the
Client Minimum Phy Rate text box, enter the minimum
transmission data rate to the client. If the transmission data rate is below
the phy rate, either the video will not start or the client may be classified
as a bad client. The bad client video can be demoted for better effort QoS or
subject to denial.
-
In the
Maximum Retry Percent (0-100%) text box, enter the
percentage of maximum retries that are allowed. The default value is 80. If it
exceeds 80, either the video will not start or the client might be classified
as a bad client. The bad client video can be demoted for better effort QoS or
subject to denial.
-
Select the
Multicast Direct Enable check box to enable the
Multicast Direct Enable field. The default value is enabled.
-
From the
Max Streams per Radio drop-down list, choose the
maximum number of streams allowed per radio from the range 0 to 20. The default
value is set to No-limit. If you choose No-limit, there is no limit set for the
number of client subscriptions.
-
From the
Max Streams per Client drop-down list, choose the
maximum number of streams allowed per client from the range 0 to 20. The
default value is set to No-limit. If you choose No-limit, there is no limit set
for the number of client subscriptions.
-
Select the
Best Effort QoS Admission check box to enable
best-effort QoS admission.
-
Click
Apply.
