The group command configures multicast groups for a global channel and limits the bandwidth to a specific value for each multicast group in the channel.
The undo group command cancels the configuration.
By default, no multicast groups are configured for a global channel, and the bandwidth is not limited for any multicast group in the channel.
| Parameter | Description | Value |
|---|---|---|
| group-address |
Specifies a multicast group address. |
The value is in dotted decimal notation. |
| group-mask |
Specifies the mask of a multicast group address. |
The value is in dotted decimal notation. |
| group-mask-length |
Specifies the mask length of a multicast group address. |
The value is an integer ranging from 5 to 32. |
| source source-address |
Specifies a multicast source address. |
The value is in dotted decimal notation. |
| source-mask |
Specifies the mask of a multicast source address. |
The value is in dotted decimal notation. |
| source-mask-length |
Specifies the mask length of a multicast source address. |
The value is an integer ranging from 8 to 32. |
| per-bandwidth bandwidth |
Sets a bandwidth limit. |
The value is an integer ranging from 1 to 131072, in kbit/s. |
Usage Scenario
If a network provides services for multiple content providers, you can run the group command to configure multicast groups for a global or VSI channel and limit the bandwidth to a specific value for each group in the channel. Therefore, this command configuration allows the device to manage content providers and control traffic in a centralized manner.
Prerequisites
A global channel has been configured.
Configuration Impact
If the bandwidth parameter is not set, the bandwidth is not limited for multicast groups.
Precautions
A multicast group in a global channel must have a unique address. It cannot have the same address as multicast groups in other global channels or multicast groups in VSI channels.
