Primary and Secondary (IP Video Input Configuration)
The following parameters appear for both the Primary and Secondary networks.
WAN Select
Specifies the WAN for this channel. Choose from WAN 1 - 4.
This field also displays the IP address and VLAN defined in the Element's IP
WAN menu.
IP Address
Specifies the IP address for the channel.
UDP Port
Specifies the UDP port for the channel.
Multicast Source
Specifies the source address for multicast assignment.
Note:
For a Primary or Secondary interface, if the IP address is set to 0.0.0.0 and the UDP port is set to
zero, no input will be expected.
IP Video Status
Switch Mode
This read-only parameter displays the switch mode for the selected
channel.
In
Make Before Break
mode, the "Next Source" stream is acquired by IGMP
Joins. The previous stream is removed after a clean transition of video and
audio by IGMP Leaves. There must be enough bandwidth remaining on the
100G Ethernet Links to have the "Next Source" stream to be present
alongside the current stream. If there is an over subscription of bandwidth,
the other channels will be disrupted due to Ethernet packets being
dropped.
In
Make After Break
mode, the current stream is lost by IGMP Leaves. If
you receive an error message under "Switch Error" indicating that the
switch failed due to timeout, change the
IGMP Leave Delay
parameter
value as described in
Configuring IP Control for SNP
(on page 59), then
perform the switch again by clicking
Take
. Assuming the timeout does not
occur, after waiting for the delay indicated in the
IGMP Leave Delay
parameter and for the current stream to be lost, the "Next Source" stream
will be acquired by IGMP joins. There will not be a clean transition of video
and audio in this switch mode.
Make After Break
will only work if the amount of bandwidth being received
by the device can dynamically change due to IGMP Leaves/Joins or with
SDNO. Otherwise
Make After Break
will always fail with a timeout
message.
Switch Status
This read-only parameter confirms the success of the switch to the next
source. The possible values are:
Ready
,
Switching
,
Switch Complete
, and
Switch Failed
.
