Configuring the Action

Alteon OS Application Guide

Each IGMP Filter allows you to set a start and end point that defines the range of IP addresses upon which the filter takes action. Each IP address in the range must be between 224.0.1.0 and 239.255.255.255. If you choose any as the start point, then the filter acts upon all addresses between 224.0.0.0 and the address entered as the end point. If you enter any as the end point, then the filter acts upon all addresses between the address entered as the start point and 239.255.255.255.

Each IGMP filter can allow or deny IP multicasts to the range of IP addresses configured. If you configure the filter to deny IP multicasts, then IGMP Membership Reports from multicast groups within the range are dropped. You can configure a secondary filter to allow IP multi- casts to a small range of addresses within a larger range that a primary filter is configured to deny. The two filters work together to allow IP multicasts to a small subset of addresses within the larger range of addresses.

Configure IGMP Filtering

1. Enable IGMP Filtering on the switch.

>> /cfg/l3/igmp/igmpflt		(Select IGMP Filtering menu)
>> IGMP Filter#	ena	(Enable IGMP Filtering)
Current status:	disabled
New status:	enabled

2.Define an IGMP filter.

>> /cfg/l3/igmp/igmpflt				(Select IGMP Filtering menu)
>>IGMP Filter# filter 1				(Select Filter 1 Definition menu)
>>IGMP Filter 1	Definition#	range 224.0.1.0 (Enter first IP address of the range)
Current multicast address2: any			any: 226.0.0.0 (Enter second IP address)
Enter new multicast address2 or
Current multicast address1:			any
New pending multicast address1:			224.0.1.0
Current multicast address2:			any
New pending multicast address2: 226.0.0.0
>>IGMP Filter 1	Definition# action deny			(Deny multicast traffic)
>>IGMP Filter 1	Definition# ena			(Enable the filter)
