The BIG-IP management interface may erroneously send IPv6 Multicast Listener Discovery (MLD) Listener Query or IPv4 Internet Group Management Protocol (IGMP) Membership Query packets.
No production traffic impact, but extra management traffic. Some switches may report an IGMP or MLD error when connected to the mgmt port.
Any platform that uses Linux interface 'mgmt' as opposed to 'eth0'. This is applicable for all platforms except the following: 1600, 3600, 3900, 6900, 8900, 8950, 11000, 11050, VE (Virtual Edition guests), and vCMP (vCMP guests hosted by BIG-IP platforms).
Disable the unwanted MLD and IGMP packets by doing the following: echo 0 > /sys/class/net/mgmt/bridge/multicast_snooping. This is applicable for all platforms except the following: 1600, 3600, 3900, 6900, 8900, 8950, 11000, 11050, VE (Virtual Edition guests), and VCMP (vCMP guests hosted by BIG-IP platforms).
Management interface no longer sends IPv6 Multicast Listener Discovery Listener Query or IPv4 Internet Group Management Protocol Membership Query packets. Note: This fix is not available for releases prior to 11.6.0. But the workaround can be used to achieve the same effect.
