To disable the port where multicast router is connected, use the following command.
Command Mode Description
no ip igmp snooping mrouter
port {PORTS | cpu}
Disables the port where multicast router is connected
on the system
no ip igmp snooping vlan
VLANS mrouter port {PORTS |
cpu }
Global
Disables the port where multicast router is connected
on a VLAN interface.
Mrouter Port Learning Method
For the hiD 6615 S323, multicast-capable router ports are added to the forwarding table
for every Layer 2 multicast entry. The switch learns such ports through snooping on PIM
packets. The switch snoops on PIM packets on all VLANs.
To configure Mrouter port learning method, use the following commands.
Command Mode Description
ip igmp snooping mrouter learn
pim
Configures the mrouter port learning method on the
system.
ip igmp snooping vlan VLANS
mrouter learn pim
Configures the mrouter port learning method on a
VLAN interface.
no ip igmp snooping mrouter
learn pim
Disables the mrouter port learning method on the sys-
tem.
no ip igmp snooping vlan
VLANS mrouter learn pim
Global
Disables the mrouter port learning method on a VLAN
interface.
Displaying Mrouter Configuration
To display IGMP snooping mrouter configuration, use the following command.
Command Mode Description
show ip igmp snooping mrouter Shows the mrouter configuration on the system.
show ip igmp snooping vlan
VLANS mrouter
Enable
Global
Bridge Shows the mrouter configuration and detail information
on a VLAN interface.
9.2.5.6 Multicast TCN Flooding
An IGMP snooping-disabled switch does not flood multicast traffic to all ports in a VLAN
when a spanning-tree Topology Change Notification (TCN) is received. A topology can
change in a VLAN and it may invalidate previously learned IGMP snooping information. A
host that was on one port before the topology change may move to another port after the
topology change. The hiD 6615 S223/S323 switch helps to deliver multicast traffic is de-
livered to all multicast receivers in that VLAN when the topology changes. When the
spanning tree protocol is running in a VLAN, a spanning tree topology change notification
(TCN) is issued by the root switch in the VLAN.
