Configuring IP Multicast Switching

IPMS Application Example

OmniSwitch AOS Release 6 Network Configuration Guide

page 42-37

The figure below shows a sample network with the switch sending multicast video. A client attached to 
Port 5 needs to be configured as a static IGMP neighbor and another client attached to Port 2 needs to be 
configured as a static IGMP querier. 

The network administrator has determined that the network is too lossy and therefore the robustness vari-
able needs to be set to a higher (i.e., 7) value.

Follow the steps below to configure this network:

Note. All the steps following Step 1 (which must be executed first) may be entered in any order.

1 Enable

 

IP Multicast Switching and Routing switch-wide,

 

by entering:

-> ip multicast status enable

2 Configure the client attached to Port 5 as a static neighbor belonging to VLAN 5 by entering:

-> ip multicast static-neighbor vlan 5 port 1/5

3 Configure the client attached to Port 2 as a static querier belonging to VLAN 5 by entering:

-> ip multicast static-querier vlan 5 port 1/2

4 Modify the robustness variable from its default value of 2 to 7 by entering:

-> ip multicast robustness 7

(source IP address)

Attached to Slot 1, Port 5.

Attached to Slot 1, Port 2.

Network clients send IGMP 
requests to receive multicast 
traffic.
