multicast-vlan

Syntax

multicast-vlan vlan-id

undo multicast-vlan { 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 multicast VLANs.

Description

Use the multicast-vlan command to configure the specified VLAN as a multicast VLAN and enter multicast VLAN view.

Use the undo multicast-vlan command to remove the specified VLAN as a multicast VLAN.

The VLAN to be configured is not a multicast VLAN by default.

Note that:

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

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

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

Related commands: multicast routing-table in the Multicast Routing and Forwarding Commands in the IP Multicast Volume; igmp-snooping enable in the IGMP Snooping Commands in the IP Multicast Volume.

Examples

# Enable IGMP Snooping in VLAN 100. Configure it as a multicast VLAN and enter multicast VLAN view.

<Sysname> system-view

[Sysname] igmp-snooping

[Sysname-igmp-snooping] quit

[Sysname] vlan 100

[Sysname-vlan100] igmp-snooping enable

[Sysname-vlan100] quit

[Sysname] multicast-vlan 100

[Sysname-mvlan-100]

port (multicast VLAN view)

Syntax

port interface-list

undo port { all | interface-list }

View

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 multicast VLAN.

Description

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

Use the undo port command to delete the specified port(s) or all ports from the current multicast VLAN.

By default, a multicast VLAN has no ports.

Note that:

l          A port can belong to only one multicast VLAN.

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

Examples

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

<Sysname> system-view

[Sysname] multicast-vlan 100

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

subvlan (multicast VLAN view)

Syntax

subvlan vlan-list

undo subvlan { all | vlan-list }

View

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 multicast VLAN.

Description

Use the subvlan command to configure sub-VLAN(s) for the current multicast VLAN.

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

A multicast VLAN has no sub-VLANs by default.

Note that:

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

l          The number of sub-VLANs of the 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 multicast VLAN 100.

<Sysname> system-view

[Sysname] multicast-vlan 100

[Sysname-mvlan-100] subvlan 10 to 15
