This section provides an example configuration for the FCC server. The configuration example has the following assumptions:
a single ISA-MS in slot 2/1 in video group 1
a single channel 192.0.2.1 within multicast bundle ‟b1” with an administrative bandwidth of 8000 kb/s defined in multicast-info-policy policy-name.
FCC mode is burst with a rate 130% of nominal for HD, 200% for SD, and disabled for PIP
local FCC server address is 10.3.3.3 and destination port is UDP 4098
The first step in the configuration is to configure video group 1 enabling the FCC server and the ISA-MS hardware.

The fcc-server command in the above output enables the FCC server on the video group.
The channel parameters for 192.0.2.1 are configured in multicast-info-policy policy-name. The channel configuration includes the administrative bandwidth and the channel’s association with video group 1.

The local-fcc-port command in the bundle ‟default” defines the destination UDP port used to reach the FCC server on the service where the multicast information policy is applied. The FCC server port can only be defined in the bundle ‟default” and applies for all bundles in the policy. If no value is specified, the default is used.
In the bundle ‟b1”, the fcc-server command enables the FCC server for all channels in the bundle, and the fcc-channel-type hd command sets the channel type for all channels in the bundle to ‟hd” (High Definition).
In the video policy context above, the fcc-server commands for the video interface 10.3.3.3 enables the FCC server on that interface for all channel types ‟hd” (High Definition), ‟sd” (Standard Definition) whereas the no fcc-server command disables the FCC for ‟pip” (Picture-in-Picture) channels on the video interface. The fcc-burst command in the policy indicates that the burst rate over the nominal rate for the channel type; HD at 130% (30% over nominal) and SD at 200% (100% over nominal).
For the FCC server in an IES or VPRN, the following commands within the service instance perform the following tasks to complete the FCC server configuration:
Associate the service with multicast-info-policy policy-name.
Create the video interface ‟vi” and assign IP address 10.3.3.3.
Create video SAP and associate it with video group 1.
Create a static IGMP join on video-interface ‟vi” for the channel 192.0.2.1.
