reset igmp group

Function

The reset igmp group command deletes records about IGMP groups that interfaces dynamically join or information about multicast groups that are configured with source-specific multicast (SSM) mapping.

Format

reset igmp group { all | interface { port-type port-num | port-name } { all | GrpAddr4 [ mask { GrpMask | GrpMaskLen } ] [ SrcAddr4 [ mask { SrcMask | SrcMaskLen } ] ] } }

reset igmp { vpn-instance vpn-instance-name | all-instance } group { all | interface { port-type port-num | port-name } { all | GrpAddr4 [ mask { GrpMask | GrpMaskLen } ] [ SrcAddr4 [ mask { SrcMask | SrcMaskLen } ] ] } }

reset igmp group ssm-mapping { all | interface { port-type port-num | port-name } { all | GrpAddr4 [ mask { GrpMask | GrpMaskLen } ] } }

reset igmp { vpn-instance vpn-instance-name | all-instance } group ssm-mapping { all | interface { port-type port-num | port-name } { all | GrpAddr4 [ mask { GrpMask | GrpMaskLen } ] } }

Parameters

Parameter	Description	Value
all	Indicates all IGMP groups.	-
interface port-type port-num	Specifies the type and number of an interface.	-
port-name	Specifies the name of an interface.	The value is a string of 1 to 63 case-sensitive characters, spaces not supported.
GrpAddr4	Specifies the address of a multicast group.	The address is in dotted decimal notation and ranges from 224.0.0.0 to 239.255.255.255.
mask	Indicates the mask of a multicast source address or group address.	-
GrpMask	Specifies the mask of a multicast group address.	The address is in dotted decimal notation and ranges from 240.0.0.0 to 255.255.255.255.
GrpMaskLen	Specifies the mask length of a multicast group address.	The value is an integer ranging from 4 to 32.
SrcAddr4	Specifies a multicast source address.	The address is in dotted decimal notation.
SrcMask	Specifies the mask of a multicast source address.	The address is in dotted decimal notation and ranges from 240.0.0.0 to 255.255.255.255.
SrcMaskLen	Specifies the mask length of a multicast source address.	The value is an integer ranging from 0 to 32.
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	The value is a string of case-sensitive characters.
all-instance	Indicates all instances.	-

Usage Guidelines

Usage Scenario

This command is valid only for IGMP groups that interfaces dynamically join.

Before using the reset igmp group command without ssm-mapping, note the following:

If neither vpn-instance nor all-instance is specified, the command deletes records about IGMP groups that interfaces in the public network instance dynamically join.
If the reset igmp group all command is used, the command deletes records about all IGMP groups that all interfaces of the device dynamically join.
If interface interface-type interface-number all is specified, the command deletes records about all IGMP groups that a specified interface dynamically joins.
If GrpAddr4 is specified, the command deletes records about a specified IGMP group.
If SrcAddr4 is specified, the command deletes records about the IGMP groups of a specified source address.
An interface can rejoin the IGMP group after records about this group are deleted.
Before using the reset igmp group ssm-mapping command, note the following:
If neither vpn-instance nor all-instance is specified, the command deletes information about multicast groups that are configured with SSM mapping in the public network instance.
If all is specified, the command deletes information about all multicast groups that are configured with SSM mapping.
If interface port-type port-number is specified, the command deletes information about multicast groups configured with SSM mapping on a specified interface.
If both interface and GrpAddr4 are specified, the command deletes information about the specified multicast group configured with SSM mapping on a specified interface.

Example

# Clear records about groups from 225.1.1.0 to 225.1.1.255 that GE 0/1/0 in the public network instance dynamically joins.

<HUAWEI> reset igmp group interface GigabitEthernet0/1/0 225.1.1.0 mask 255.255.255.0

# Clear records about the group 225.0.0.1 that GE 0/1/0 in the public network instance dynamically joins.

<HUAWEI> reset igmp group interface GigabitEthernet0/1/0 225.0.0.1

# Clear records about IGMP groups that GE 0/1/0 in the public network instance dynamically joins.

<HUAWEI> reset igmp group interface GigabitEthernet0/1/0 all

# Clear records about IGMP groups that all interfaces in the public network instance dynamically join.

<HUAWEI> reset igmp group all

# Delete information about multicast groups that are configured with SSM mapping rules on all interfaces.

<HUAWEI> reset igmp group ssm-mapping all
