display multicast-vlan ipv6

Syntax

display multicast-vlan ipv6 [ vlan-id ] [ | { begin | exclude | include } regular-expression ]

View

Any view

Default level

1: Monitor level

Parameters

vlan-id: VLAN ID of an IPv6 multicast VLAN, in the range of 1 to 4094. If this argument is not provided, the information about all IPv6 multicast VLANs will be displayed.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use the display multicast-vlan ipv6 command to view the information about the specified IPv6 multicast VLAN or all IPv6 multicast VLANs.

Examples

# View the information about all IPv6 multicast VLANs.

<Sysname> display multicast-vlan ipv6

 Total 1 IPv6 multicast-vlan(s)

 

 IPv6 Multicast vlan 100

   subvlan list:

    vlan 2  4-6

Table 1 Output description

Field	Description
Total 1 IPv6 multicast-vlan(s)	Total number of IPv6 multicast VLANs
IPv6 Multicast vlan	An IPv6 multicast VLAN
subvlan list	List of sub-VLANs of the IPv6 multicast VLAN

 

multicast-vlan ipv6

Syntax

multicast-vlan ipv6 vlan-id

undo multicast-vlan ipv6 { all | vlan-id }

View

System view

Default level

2: System level

Parameters

vlan-id: Specifies a VLAN by its ID, in the range of 1 to 4094.

all: Deletes all IPv6 multicast VLANs.

Description

Use the multicast-vlan ipv6 command to configure the specified VLAN as an IPv6 multicast VLAN and enter IPv6 multicast VLAN view.

Use the undo multicast-vlan ipv6 command to remove the specified VLAN as an IPv6 multicast VLAN.

No VLAN is an IPv6 multicast VLAN by default.

The specified VLAN to be configured as an IPv6 multicast VLAN must exist.

The IPv6 multicast VLAN feature cannot be enabled on a device with IPv6 multicast routing enabled.

You need to enable MLD snooping only in the IPv6 multicast VLAN.

Related commands: mld-snooping enable and multicast ipv6 routing-enable.

Examples

# Enable MLD snooping in VLAN 100. Configure it as an IPv6 multicast VLAN and enter IPv6 multicast VLAN view.

<Sysname> system-view

[Sysname] mld-snooping

[Sysname-mld-snooping] quit

[Sysname] vlan 100

[Sysname-vlan100] mld-snooping enable

[Sysname-vlan100] quit

[Sysname] multicast-vlan ipv6 100

[Sysname-ipv6-mvlan-100]

multicast-vlan ipv6 entry-limit

Syntax

multicast-vlan ipv6 entry-limit limit

undo multicast-vlan ipv6 entry-limit

View

System view

Default level

2: System level

Parameters

limit: Maximum number of entries in the MLD snooping forwarding table of IPv6 multicast VLANs. The value range varies with the system working modes. For more information, see Fundamentals Configuration Guide.

Description

Use the multicast-vlan ipv6 entry-limit command to configure the maximum number of MLD snooping forwarding entries of IPv6 multicast VLANs.

Use the undo multicast-vlan ipv6 entry-limit command to restore the default.

The default upper limit depends on the system working mode. For more information, see Fundamentals Configuration Guide.

Related commands: entry-limit.

Examples

# Configure the MLD snooping forwarding table of the IPv6 multicast VLANs to contain 512 entries at most.

<Sysname> system-view

[Sysname] multicast-vlan ipv6 entry-limit 512

subvlan (IPv6 multicast VLAN view)

Syntax

subvlan vlan-list

undo subvlan { all | vlan-list }

View

IPv6 multicast VLAN view

Default level

2: System level

Parameters

vlan-list: Specifies a VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The value range of a VLAN ID is 1 to 4094.

all: Deletes all the sub-VLANs of the current IPv6 multicast VLAN.

Description

Use the subvlan command to configure sub-VLAN or sub-VLANs for the current IPv6 multicast VLAN.

Use the undo subvlan command to remove the specified sub-VLAN or sub-VLANs or all sub-VLANs from the current IPv6 multicast VLAN.

An IPv6 multicast VLAN has no sub-VLANs by default.

The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must have existed.

The number of sub-VLANs of the IPv6 multicast VLAN must not exceed 1024.

Examples

# Configure VLAN 10 through VLAN 15 as sub-VLANs of IPv6 multicast VLAN 100.

<Sysname> system-view

[Sysname] multicast-vlan ipv6 100

[Sysname-ipv6-mvlan-100] subvlan 10 to 15
