DES-7200 Configuration Guide Chapter 8 IGMP Snooping
Configuration
8-18
Command Function
DES-7200(config)# interface interface-id
Enter the interface to be configured.
DES-7200(config-if)# ip igmp snooping
filter profile-number
(Optional) Apply Profile to this interface.
The range of profile number if 1-1024. By
default, a port is not associated with any
profile.
DES-7200(config-if)# no ip igmp
snooping filter
(Optional) Delete the profile associated to
the interface, which will then permit all
groups.
DES-7200(config-if)# ip igmp snooping
max-groups number
(Optional) Configure the maximum number
(0-1024) of groups that can be joined on
this port. The number is not restricted by
default.
The following example shows how to configure the filter:
DES-7200# configure terminal
DES-7200(config)# interface fastEthernet 0/1
DES-7200(config-if)# ip igmp snooping filter 1
DES-7200(config-if)# ip igmp snooping max-groups 1000
DES-7200(config-if)# end
DES-7200# show ip igmp snooping interface fastEthernet 0/1
Interface Filter profile number max-group

8.2.12.4 Configuring VLAN Filter
Under certain circumstances, you may need to control the reception of multicast
traffic on the egress of specific VLAN. VLAN-based filter well meets such need.
You can apply an IMGP Profile to a VLAN. If IMGP Report packets are received
on the port belong to this VLAN, the layer-2 multicast device will verify whether
the multicast address to be joined by this port falls within the range permitted by
IGMP Profile. If yes, the port will join and process subsequently.
In global configuration mode, execute the following steps to configure IGMP
Filtering:
Command Function
DES-7200(config)# ip igmp snooping
vlan num filter profile-number
(Optional) Apply Profile to this VLAN. The
range of profile number if 1-1024. By default,
a VLAN is not associated with any profile.
DES-7200(config-if)# no ip igmp
snooping vlan num filter
(Optional) Delete the profile associated to the
VLAN, which will then permit all groups.
The following example shows how to configure the VLAN filter:
DES-7200# configure terminal
DES-7200(config)# interface fastEthernet 0/1
DES-7200(config-if)# ip igmp snooping vlan 2 filter 1
