1.1.5 igmp-snooping

Syntax

igmp-snooping { enable | disable }

View

System view, VLAN view

Parameters

enable: Enables IGMP Snooping.

disable: Disables IGMP Snooping;

Description

Use the igmp-snooping enable command to enable IGMP Snooping globally or in a VLAN.

Use the igmp-snooping disable command to disable IGMP Snooping.

By default, the switch disables IGMP Snooping.




Caution:

When configuring IGMP Snooping, first enable global IGMP Snooping in system view, and then enable IGMP Snooping in VLAN view. Otherwise the IGMP Snooping function will not take effect.

If the VLAN VPN is enabled on a port, the IGMP Snooping feature cannot be enabled on the VLAN for the port or the IGMP feature cannot be enabled on the corresponding VLAN interface.

If IGMP Snooping feature is enabled in a VLAN, or IGMP is enabled on the VLAN interface, you cannot add the member port on which VLAN VPN is enabled into the VLAN.

Isolate-user-VLAN supports the IGMP-Snooping function. After IGMP-Snooping is enabled under isolate-user-VLAN, all secondary VLANs are IGMP-Snooping enabled.

In a secondary VLAN, IGMP packets will be directly converted and processed in isolate-user-VLAN, namely all the multicast services are implemented within isolate-user-VLAN.

Ports in secondary VLANs cannot be used as source addresses of multicast. If the undo igmp-snooping command is executed in system view, all IGMP

Snooping configurations previously made are removed.

Examples

# Enable IGMP Snooping in system view.

<Quidway> system-view

System View: return to User View with Ctrl+Z.

[Quidway] igmp-snooping enable

# Enable IGMP Snooping on VLAN 10

1.1.6 igmp-snooping 10ge-non-flooding enable slot

Syntax

igmp-snooping 10ge-non-flooding enable slot slot-num

undo igmp-snooping 10ge-non-flooding enable slot slot-num




1-7

View

System view

Parameters

slot-num: Slot number of the interface board.

Description

Use the igmp-snooping 10ge-non-flooding enable slot command to suppress the ports on the specified interface board from flooding unknown multicast packets at Layer 2.

Use the undo igmp-snooping 10ge-non-flooding enable slot command to remove the configuration.

By default, a port floods unknown multicast traffic at Layer 2.

Note:

Currently, this command is not supported.

Examples

# Suppress the interface board at Slot 5 from flooding unknown multicast traffic at Layer 2.



[Quidway] igmp-snooping 10ge-non-flooding enable slot 5

1.1.7 igmp-snooping fast-leave

Syntax

igmp-snooping fast-leave [ vlan { vlan-id [ to vlan-id ] }&<1-10> ]

undo igmp-snooping fast-leave [ vlan { vlan-id [ to vlan-id ] } &<1-10> ]

View

System view, Ethernet port view

Parameters

vlan { vlan-id [ to vlan-id ] }&<1-10>: Specifies any VLAN or VLAN scope for port you want to enable/disable the IGMP Snooping fast leave feature on. The vlan-id argument ranges from 1 to 4094.




Description

Use the igmp-snooping fast-leave command to enable IGMP Snooping fast leave.

Use the undo igmp-snooping fast-leave command to disable IGMP Snooping fast leave.

You can optionally specify multiple VLANs in the igmp-snooping fast-leave command, through which you can enable IGMP Snooping fast leave in the corresponding VLANs. If you do not specify any VLAN, IGMP Snooping fast leave is enabled in all VLANs.

Note:

Fast leaves that are configured in system view and Ethernet port view operate separately.

Fast leave works on all ports of the specified VLANs if you configure it in system view. However, it only works on the current port (e.g., a port operates as a trunk of multiple VLANs) in the specified VLANs if you configure it in Ethernet port view.

Caution:

Fast leave configured for a port takes effect only when the VLAN it belongs to is IGMP Snooping-enabled.

Fast leave does not work if the corresponding specified VLANs do not exist, the port does not belongs to any of the specified VLANs, or the VLANs do not have IGMP Snooping enabled.

A newly configured IGMP Snooping clears all existing fast leave configurations. The igmp-snooping fast-leave command is useless if you do not enable IGMP

Snooping globally. (You can enable IGMP Snooping globally by executing the igmp-snooping enable command in system view.)

When you configure IGMP Snooping fast leave on aggregation ports, the configuration takes effect only on primary aggregation ports.

If you add an IGMP V1 host of the same multicast group to the port, the switch does not remove the port when the port receives an IGMP Leave packet of the multicast group even you enable IGMP Snooping fast leave for the port.

Fast leave is disabled by default.





1-9

Examples

# Enable IGMP Snooping fast leave on Ethernet2/1/1 for VLAN 5, VLAN 7, VLAN 8, VLAN 30 through VLAN 40, and VLAN 50.



[Quidway] interface Ethernet2/1/1

[Quidway-Ethernet2/1/1] igmp-snooping fast-leave vlan 5 7 to 8 30 to 40 50

# Enable IGMP Snooping fast leave for all Ethernet ports except those in VLAN 5.



[Quidway] igmp-snooping fast-leave

[Quidway] undo igmp-snooping fast-leave vlan 5

1.1.8 igmp-snooping group-policy

Syntax

igmp-snooping group-policy acl-number

undo igmp-snooping group-policy

View

VLAN view

Parameters

acl-number: Number of basic ACL, in the range of 2,000 to 2,999.

Description

Use the igmp-snooping group-policy command to configure the filtering rule of multicast groups on a specified VLAN so as to control the access to IP multicast groups. You can configure only one ACL rule for each VLAN, and the new configured rule will replace the old one.

Use the undo igmp-snooping group-policy command to remove the configuration.

By default, no filtering rule is set in a VLAN. In this case, a host can join any multicast group.

If an ACL is configured in a VLAN to filter multicast groups, hosts can join only those multicast groups that are permitted to join.

Examples

# Create ACL2001 and configure the rule for basic ACL, using the source IP address as the destination multicast address.






[Quidway]acl number 2001

[Quidway-acl-basic-2001]rule 0 permit source 224.1.1.1 0

[Quidway-acl-basic-2001]quit

# Create VLAN 2.



[Quidway] vlan 2

# Configure the filtering rule of multicast groups in VLAN 2.

Description

Use the igmp-snooping host-aging-time command to configure the port aging time of the multicast group members.

Use the undo igmp-snooping host-aging-time command to restore the default value.

This command is used to set the aging time of the multicast group member so that the refresh frequency can be controlled. When the group members change frequently, the aging time should be comparatively short, and vice versa.


Examples

# Set the aging time to 300 seconds.



[Quidway] igmp-snooping host-aging-time 300




1-11

1.1.10 igmp-snooping host-port vlan
