Clearing the group information of IGMP deletes the added IGMP groups. As a result, receivers cannot receive multicast information normally. Therefore, you need to perform the operation with caution.
Table 1 shows the related operations for clearing the group information of IGMP.
| Operation | Command |
|---|---|
Clear statistics about IGMP messages. |
reset igmp [ vpn-instance vpn-instance-name | all-instance ] control-message counters [ interface interface-type interface-number ] [ message-type { query | report } ] |
Delete the hosts that dynamically join a multicast group through IGMP on an interface. |
reset igmp [ vpn-instance vpn-instance-name | all-instance ] explicit-tracking { all | interface interface-type interface-number [ host host-address [ group group-address [ source source-address ] ] ] } |
Delete all IGMP group records that the interfaces dynamically join. |
reset igmp [ vpn-instance vpn-instance-name | all-instance ] group { all | interface interface-type interface-number { all | group-address [ mask { group-mask | group-mask-length } ] [ source-address [ mask { source-mask | source-mask-length } ] ] } } |
Delete information about all the multicast groups that are configured with SSM mapping. |
reset igmp [ vpn-instance vpn-instance-name | all-instance ] group ssm-mapping { all | interface interface-type interface-number { all | group-address [ mask { group-mask | group-mask-length } ] } } |
Delete a multicast group that an interface statically joins. |
undo igmp static-group { all | group-address [ inc-step-mask { group-mask | group-mask-length } number group-number ] [ source source-address ] } |
