igmp-snooping query-pkt-deny
undo igmp-snooping query-pkt-deny
View
Ethernet port view
Parameters
None
Description
Use the igmp-snooping query-pkt-deny command to disable a port from becoming a router port.
Use the undo igmp-snooping query-pkt-deny command to cancel the configuration.
By default, a port is not disabled from becoming a router port.
After you execute this command on a port of a switch, the switch does not forward IGMP query
messages received from the port nor maintains it as a router port. This feature is mainly used in MFF
networks to prevent user ports from forwarding IGMP membership report messages to other hosts, thus
protecting Layer 2 isolation.
