DES-7200 Configuration Guide Chapter 8 IGMP Snooping
Configuration
8-13
Command Function
DES-7200(config)# no ip igmp
Snooping
query-max-response-time
Restore the maximum
response time to the default
value.
The following example configures the maximum response time of the IGMP
Query message to 15s:
DES-7200# configure terminal
DES-7200 (config) # ip igmp snooping query-max-response-time 15
8.2.9 Configuring IGMP Profiles
An IGMP Profile entry defines a set of multicast address range and permit/deny
activity for the funcitons like multicast address range for SVGL mode, multicast
data range filtered on the router interface, and IGMP Filtering range. Note that
modifying an IGMP Profile after associating it with a function will influence the
multicast forwarding table generated by the function.
To configure an IGMP profile, execute the following commands:
Command Function
DES-7200(config)# ip igmp
profile
profile-number
Enter the IGMP Profile mode. Assign a number in the
range of 1 to 1024 to identify. By default, no profile is
configured.
DES-7200 (config-profile)#
permit |
deny
(Optional) Permit or deny this range of multicast
addresses while deny or permit other multicast
addresses. The default value is deny.
DES-7200(config-profile)#
range ip
multicast-address
Add one or more multicast address ranges.
DES-7200# end
Return to the privileged mode.
To delete an IGMP Profile, use no ip igmp profile profile-number.
To delete a range of the IGMP Profile, use no range ip multicast address.
This example shows the IGMP Profile configuration process:
DES-7200(config)# ip igmp profile 1
DES-7200 (config-profile) # permit
DES-7200 (config-profile) # range 224.0.1.0 239.255.255.255
DES-7200 (config-profile) # end
DES-7200# show ip igmp profile 1
IGMP Profile 1
permit
range 224.0.1.0 239.255.255.255
As you can see, the rule of the IGMP Profile is to permit the multicast addresses
from 224.0.1.0 to 239.255.255.255, while all other multicast addresses are
denied.
8.2.10 Configuring the Multicast Address Range in the SVGL /IVGL-SVGL
Mode
When the IGMP Snooping works in the SVGL or IVGL-SVGL mode, a profile shall
be associated to specify the multicast group address range applied in the SVGL
or IVGL-SVGL mode. That is to say, the member ports of the multicast forwarding
entry can be forwarded across VLANs while the member ports of the multicast
forwarding entry in the other multicast address range must belong to the same
VLAN. By default, no profile is associated.
