Multicast 8clear ip multicastSyntax: clear ip multicast [all | group ]• all - Clears the learned flows for all groups.• group - Clears the flows for the specified group, but does not clear the flows forother groups.This command resets statistics counters to zero for all the statistics displayed by the show ipmulticast statistics command.The following example shows IGMP flows information listed by the show ip multicast command,followed by removal of the information by the clear ip multicast all command.Brocade# show ip multicastIP multicast is enabled - ActiveVLAN ID 1Active 192.168.2.30 Router Ports 4/13Multicast Group: 239.255.162.5, Port: 4/4 4/13Multicast Group: 239.255.162.4, Port: 4/10 4/13Brocade# clear ip multicast allBrocade# show ip multicastIP multicast is enabled - ActiveVLAN ID 1Active 192.168.2.30 Router Ports 4/13To clear the learned IGMP flows for a specific IP multicast group, use the clear ip multicast groupcommand.The following example shows how to clear the IGMP flows for a specific group and retain reports forother groups.Brocade# show ip multicastIP multicast is enabled - ActiveVLAN ID 1Active 192.168.2.30 Router Ports 4/13Multicast Group: 239.255.162.5, Port: 4/4 4/13Multicast Group: 239.255.162.4, Port: 4/10 4/13Brocade# clear ip multicast group 239.255.162.5Brocade# show ip multicastIP multicast is enabled - ActiveVLAN ID 1Active 192.168.2.30 Router Ports 4/13Multicast Group: 239.255.162.4, Port: 4/10 4/13Configuration notesYou must enter the ip multicast-routing command before changing the global IP multicastparameters. Otherwise, the changes do not take effect and the software uses the default values.Also, entering no ip multicast-routing will reset all parameters to their default values.Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 28353-1002426-02
