group (VSI channel-name view)

Function

The group command configures multicast groups for a VSI 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 VSI channel, and the bandwidth is not limited for any multicast group in the channel.

Format

group group-address { group-mask | group-mask-length } [ source source-address { source-mask | source-mask-length } ] [ per-bandwidth bandwidth ]

undo group group-address { group-mask | group-mask-length } [ source source-address { source-mask | source-mask-length } ]

Parameters

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 Guidelines

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 VSI channel has been configured.

Configuration Impact

If the bandwidth parameter is not set, the bandwidth is not limited for multicast groups.

Precautions

A group in a channel of a VSI cannot have the same address as multicast groups in other channels in the VSI.

Example

# Configure multicast groups for a channel named al in VSI vsi1.
