Chapter 17 Configuring IGMP Snooping and MVR Configuring IGMP Filtering Default IGMP Filtering Configuration Table 17-7 shows the default IGMP filtering configuration. Table 17-7 Default IGMP Filtering Configuration Feature IGMP filters IGMP Maximum number of IGMP groups IGMP profiles IGMP profile action Default Setting None applied No maximum set None defined Deny the range addresses Configuring IGMP Profiles To configure an IGMP profile, use the ip igmp profile global configuration command with a profile number to create an IGMP profile and to enter IGMP profile configuration mode. From this mode, you can specify the parameters of the IGMP profile to be used for filtering IGMP join requests from a port. When you are in IGMP profile configuration mode, you can create the profile by using these commands: • deny: Specifies that matching addresses are denied; this is the default condition. • exit: Exits from igmp-profile configuration mode. • no: Negates a command or sets its defaults. • permit: Specifies that matching addresses are permitted. • range: Specifies a range of IP addresses for the profile. You can enter a single IP address or a range with a start and an end address. The default is for the switch to have no IGMP profiles configured. When a profile is configured, if neither the permit nor deny keyword is included, the default is to deny access to the range of IP addresses. Beginning in privileged EXEC mode, follow these steps to create an IGMP profile: Step 1 Step 2 Command configure terminal ip igmp profile profile number Step 3 permit | deny Step 4 range ip multicast address Step 5 end Purpose Enter global configuration mode. Enter IGMP profile configuration mode, and assign a number to the profile you are configuring. The range is from 1 to 4294967295. (Optional) Set the action to permit or deny access to the IP multicast address. If no action is configured, the default for the profile is to deny access. Enter the IP multicast address or range of IP multicast addresses to which access is being controlled. If entering a range, enter the low IP multicast address, a space, and the high IP multicast address. You can use the range command multiple times to enter multiple addresses or ranges of addresses. Return to privileged EXEC mode. 78-14982-01 Catalyst 2950 Desktop Switch Software Configuration Guide 17-21
