Clearing IGMP Snooping Over VXLAN Entries

Clearing IGMP Snooping Over VXLAN Entries


IGMP snooping over VXLAN entries are classified into static and dynamic entries, and they are cleared in different ways.

Static entries cannot be restored after being cleared and can be created when you configure static member ports.

When dynamic entries in a forwarding table are cleared, the hosts in the BD do not receive the multicast packets temporarily. The hosts in the BD receive the multicast packets again only after the hosts send IGMP Report messages and the forwarding entries are regenerated on the switch.


  • Run the undo igmp snooping static-group [ source-address source-ip-address ] group-address { group-ip-address | all } [ dot1q vid vid | qinq pe-vid pe-vid ce-vid ce-vid ] command in the Layer 2 sub-interface view to remove the Layer 2 sub-interface from a multicast group.
  • Run the reset igmp snooping group { all | bridge-domain { all | bd-id } } command in the user view to remove dynamic entries in a forwarding table.
