IPv6 Multicast VLAN Configuration Commands

display multicast-vlan ipv6

Syntax

display multicast-vlan ipv6 [ vlan-id ]

View

Any view

Default Level

1: Monitor level

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

 IPv6 Multicast vlan 100

   subvlan list:

    vlan 2  4-6

   port list:

    no port

 IPv6 Multicast vlan 200

   subvlan list:

Table 1-1 display multicast-vlan ipv6 command output description

Field	Description
Total 4 IPv6 multicast-vlan(s)	Total number of IPv6 multicast VLANs

subvlan list	List of sub-VLANs of the IPv6 multicast VLAN
port list	Port list 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.

Note that:

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

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

l          For a sub-VLAN-based IPv6 multicast VLAN, you need to enable MLD Snooping only in the IPv6 multicast VLAN; for a port-based IPv6 multicast VLAN, you need to enable MLD Snooping in both the IPv6 multicast VLAN and all the user VLANs.

Related commands: multicast ipv6 routing-table in the IPv6 Multicast Routing and Forwarding Commands in the IP Multicast Volume; mld-snooping enable in the MLD Snooping Commands in the IP Multicast Volume.

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]

port (IPv6 multicast VLAN view)

Syntax

port interface-list

undo port { all | interface-list }

View

IPv6 multicast VLAN view

Default Level

2: System level

Parameters

interface-list: Specifies a port in the form of interface-type interface-number, or a port range in the form of interface-type start-interface-number to interface-type end-interface-number, where the end interface number must be greater than the start interface number.

all: Deletes all the ports in the current IPv6 multicast VLAN.

Description

Use the port command to assign port(s) to the current IPv6 multicast VLAN.

Use the undo port command to delete port(s) from the current IPv6 multicast VLAN.

By default, an IPv6 multicast VLAN has no ports.

Note that:

l          A port can belong to only one IPv6 multicast VLAN.

l          Only the following types of interfaces can be configured as IPv6 multicast VLAN ports: Ethernet, and Layer 2 aggregate interfaces.

Examples

# Assign ports GigabitEthernet 2/0/1 through GigabitEthernet 2/0/5 to IPv6 multicast VLAN 100.

<Sysname> system-view

[Sysname] multicast-vlan ipv6 100

[Sysname-ipv6-mvlan-100] port gigabitethernet 2/0/1 to gigabitethernet 2/0/5

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 effective 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(s) for the current IPv6 multicast VLAN.

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

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

Note that:

l          The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must exist and must not be IPv6 multicast VLANs or sub-VLANs of another IPv6 multicast VLAN.

l          The number of sub-VLANs of the IPv6 multicast VLAN must not exceed the system-defined limit (an S7500E series Ethernet switch supports up to five multicast VLANs, and supports up to 4000 sub-VLANs for each multicast VLAN. The total number of sub-VLANs for all multicast VLANs on the switch cannot exceed 4000.).

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
