Views

IGMP-snooping view

Predefined user roles

network-admin

Parameters

ipv4-acl-number: Specifies an IPv4 basic or advanced ACL by its number in the range of 2000 to 3999. Hosts can join only the multicast groups that the ACL permits. If the ACL does not exist or does not have valid rules, hosts cannot join multicast groups.

vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect on all VLANs.

Usage guidelines

A multicast group policy filters IGMP reports to control the multicast groups that hosts can join.

This command does not take effect on static member ports, because static member ports do not send IGMP reports.

You can configure a multicast group policy globally for all ports in IGMP-snooping view or for a port in interface view. For a port, the port-specific configuration takes priority over the global configuration.

When you configure a rule in the IPv4 ACL, follow these restrictions and guidelines:

·          In a basic ACL, the source source-address source-wildcard option specifies a multicast group address.

·          In an advanced ACL, the source source-address source-wildcard option specifies a multicast source address. The destination dest-address dest-wildcard option specifies a multicast group address.

To match the following IGMP reports, set the source source-address source-wildcard option to 0.0.0.0:

¡  IGMPv1 and IGMPv2 reports.

¡  IGMPv3 IS_EX and IGMPv3 TO_EX reports that do not carry multicast source addresses.

·          Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

You can configure different ACLs for all ports in different VLANs. If you configure multiple ACLs for all ports in the same VLAN, the most recent configuration takes effect.

Examples

# Configure a multicast group policy for VLAN 2 so that hosts in VLAN 2 can join only multicast group 225.1.1.1.

<Sysname> system-view

[Sysname] acl basic 2000

[Sysname-acl-ipv4-basic-2000] rule permit source 225.1.1.1 0

Predefined user roles

network-admin

Parameters

seconds: Specifies an aging timer for dynamic member ports, in the range of 1 to 8097894 seconds.

Usage guidelines

You can set the timer globally for all VLANs in IGMP-snooping view or for a VLAN in VLAN view. For a VLAN, the VLAN-specific configuration takes priority over the global configuration.

To avoid mistakenly deleting multicast group members, set the aging timer for dynamic member ports to be greater than the value calculated by using the following formula:

[ IGMP general query interval ] + [ maximum response time for IGMP general queries ]

As a best practice, set the aging timer of dynamic member ports to the value calculated by using the following formula:

[ IGMP general query interval ] × 2 + [ maximum response time for IGMP general queries ]

Examples

# Set the global aging timer for dynamic member ports to 300 seconds.

ipv4-acl-number: Specifies an IPv4 basic or advanced ACL by its number, in the range of 2000 to 3999. Multicast users can join or leave only the multicast groups that the ACL permits. If the ACL does not exist or does not have valid rules, multicast users cannot join or leave any multicast groups.

all: Specifies all IGMP snooping access control policies.

Usage guidelines

You can repeat this command to configure multiple IGMP snooping access control policies. A multicast user can join or leave a multicast group if its IGMP report or leave message is permitted by one of the IGMP snooping access control policies.

When you configure a rule in the IPv4 ACL, follow these restrictions and guidelines:

·          In a basic ACL, the source source-address source-wildcard option specifies a multicast group address.

·          In an advanced ACL, the source source-address source-wildcard option specifies a multicast source address. The destination dest-address dest-wildcard option specifies a multicast group address.

To match the following IGMP messages, set the source source-address source-wildcard option to 0.0.0.0:

¡  IGMPv1 report and leave messages.

¡  IGMPv2 report and leave messages.

¡  IGMPv3 IS_EX and IGMPv3 TO_EX reports that do not carry multicast source addresses.

·          Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

Use igmp-snooping group-policy to configure a multicast group policy on a port to control the multicast groups that hosts attached to the port can join.

Use undo igmp-snooping group-policy to delete multicast group policies on a port.

Syntax

igmp-snooping group-policy ipv4-acl-number [ vlan vlan-list ]

undo igmp-snooping group-policy [ vlan vlan-list ]

Default

No multicast group polices exist on a port. Hosts attached to the port can join any multicast groups.

Parameters

ipv4-acl-number: Specifies an IPv4 basic or advanced ACL by its number in the range of 2000 to 3999. Hosts can join only the multicast groups that the ACL permits. If the ACL does not exist or does not have valid rules, hosts cannot join multicast groups.

vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect on all VLANs.

Usage guidelines

A multicast group policy filters IGMP reports to control the multicast groups that hosts can join.

This command does not take effect on static member ports, because static member ports do not send IGMP reports.

You can configure a multicast group policy for a port in interface view or globally for all ports in IGMP-snooping view. For a port, the port-specific configuration takes priority over the global configuration.

When you configure a rule in the IPv4 ACL, follow these restrictions and guidelines:

·          In a basic ACL, the source source-address source-wildcard option specifies a multicast group address.

·          In an advanced ACL, the source source-address source-wildcard option specifies a multicast source address. The destination dest-address dest-wildcard option specifies a multicast group address.

To match the following IGMP reports, set the source source-address source-wildcard option to 0.0.0.0:

¡  IGMPv1 and IGMPv2 reports.

¡  IGMPv3 IS_EX and IGMPv3 TO_EX reports that do not carry multicast source addresses.

·          Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

You can configure different ACLs on a port for different VLANs. If you configure multiple ACLs on a port for the same VLAN, the most recent configuration takes effect.

Examples

# On GigabitEthernet 1/0/1, configure a multicast group policy for VLAN 2 so that hosts in VLAN 2 can join only multicast group 225.1.1.1.

<Sysname> system-view

Predefined user roles

network-admin

Parameters

seconds: Specifies an aging timer for dynamic member ports, in the range of 1 to 8097894 seconds.

Usage guidelines

You must enable IGMP snooping for a VLAN before you execute this command.

You can set the timer for a VLAN in VLAN view or globally for all VLANs in IGMP-snooping view. For a VLAN, the VLAN-specific configuration takes priority over the global configuration.

To avoid mistakenly deleting multicast group members, set the aging timer for dynamic member ports to be greater than the value calculated by using the following formula:

[ IGMP general query interval ] + [ maximum response time for IGMP general queries ]

As a best practice, set the aging timer of dynamic member ports to the value calculated by using the following formula:

[ IGMP general query interval ] × 2 + [ maximum response time for IGMP general queries ]

Examples

# In VLAN 2, enable IGMP snooping, and set the aging timer for dynamic member ports to 300 seconds.

Parameters

group-address: Specifies a multicast group in the range of 224.0.1.0 to 239.255.255.255.

source-ip source-address: Specifies a multicast source by its IP address. If you specify a multicast source, this command configures the port as a simulated member host for a multicast source and group. If you do not specify a multicast source, this command configures the port as a simulated member host for a multicast group. This option takes effect on IGMPv3 snooping devices.

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

all: Specifies all multicast groups.

Usage guidelines

The version of IGMP running on a simulated member host is the same as the version of IGMP snooping running on the port. The port ages out in the same way as a dynamic member port.

Examples

# Configure GigabitEthernet 1/0/1 as a simulated member host of the multicast source and group (1.1.1.1, 232.1.1.1) in VLAN 2.

mac-address multicast

Use mac-address multicast to configure a static multicast MAC address entry.

Use undo mac-address multicast to delete a static multicast MAC address entry.

Syntax

In system view:

mac-address multicast mac-address interface interface-list vlan vlan-id

undo mac-address [ multicast ] [ [ mac-address [ interface interface-list ] ] vlan vlan-id ]

In Layer 2 aggregate interface view or Layer 2 Ethernet interface view:

mac-address multicast mac-address vlan vlan-id

undo mac-address [ multicast ] mac-address vlan vlan-id

Default

No static multicast MAC address entries exist.

Predefined user roles

network-admin

Parameters

mac-address: Specifies a static multicast MAC address, in the format of H-H-H. You must specify an unused multicast MAC address. A multicast MAC address is a MAC address in which the least significant bit of the most significant octet is 1.

interface interface-list: Specifies a space-separated list of up to four interface items. Each item specifies an interface or an interface list in the format of start-interface-type interface-number to end-interface-type interface-number. The interface-type interface-number argument specifies an interface by its type and number. The available interface types include Layer 2 Ethernet interfaces and Layer 2 aggregate interfaces.

vlan vlan-id: Specifies an existing VLAN by its VLAN ID in the range of 1 to 4094. The system gives a prompt if the specified interface does not belong to the VLAN.

Usage guidelines

You do not need to enable IP multicast routing before you execute this command.

You can configure static multicast MAC address entries for the specified interfaces in system view or for the current interface in interface view.

If you do not specify the multicast keyword in the undo mac-address command, all static unicast MAC address entries and static multicast MAC entries are deleted.

Examples

# Configure a static multicast MAC address entry. In the entry, the multicast MAC address is 0100-5E00-0003 and the outgoing ports are GigabitEthernet 1/0/1 through GigabitEthernet 1/0/5 in VLAN 2.

<Sysname> system-view

[Sysname] mac-address multicast 0100-5e00-0003 interface gigabitethernet 1/0/1 to gigabitethernet 1/0/5 vlan 2

# Configure a static multicast MAC address entry on GigabitEthernet 1/0/1. In the entry, the multicast MAC address is 0100-5E00-0003 and the outgoing port is GigabitEthernet 1/0/1, which belongs to VLAN 2.

<Sysname> system-view
