To disable the port where multicast router is connected, use the following command. 

 {PORTS | cpu} 

Disables the port where multicast router is connected 
on the system 

 

  mrouter port  {PORTS  | 

} 

Global 

Disables the port where multicast router is connected 
on a VLAN interface. 

 

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. 

Configures the mrouter port learning method on the 
system. 

  VLANS 

 

Configures the mrouter port learning method on a 
VLAN interface. 

Disables the mrouter port learning method on the sys-
tem. 

 

 mrouter learn pim 

Global 

Disables the mrouter port learning method on a VLAN 
interface. 

 

To display IGMP snooping mrouter configuration, use the following command. 

Shows the mrouter configuration on the system. 

 

 mrouter 

Enable 

Global 
Bridge 

Shows the mrouter configuration and detail information 
on a VLAN interface. 

 

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.
