DES-7200 Configuration Guide Chapter 3 IGMP
Configuration
3-8
Command Function
DES-7200 (config-if) # exit
Enter the privileged configuration mode.
Use the no ip igmp join-group group-address command to leave the multicast
group.
3.2.12 Configuring static-group
Use this command in the interface configuration mode to add an interface into a
static group:
Command Function
DES-7200 (config-if) # config terminal
Enter the global configuration mode.
DES-7200 (config)# interface
interface-id
Enter the interface configuration mode.
DES-7200(config-if)# ip igmp
static-group group-address
Configure the interface to join the static
group.
DES-7200 (config-if) # exit
Enter the privileged configuration mode.
Use the no ip igmp static-group group-address command to leave the static
group.
3.2.13 Configuring the Limit of IGMP Group Members
This command configures the limit of IGMP group members globally. The
messages of the members that exceed the limit will not be cached or forwarded.
You can configure this command on interfaces individually in interface mode or
globally. The messages of the members that exceed the limit configured on an
interface or globally will be ignored.
To configure the limit of IGMP group members, execute the following commands
in the interface mode.
Command Function
DES-7200(config) # ip igmp limt
number
Configure the limit of IGMP members
globally.
The limit depends on specific products. By
default, it is 65536.
DES-7200(config-if) # ip igmp limit
number
Configure the limit of IGMP members on the
interface.
The limit depends on specific products. By
default, it is 1024.
3.2.14 Configuring IGMP PROXY - SERVICE
This command enables service on all the downlink mroute-proxy interfaces. After
you configure this command on an interface, the interface becomes the uplink
interface of the corresponding mroute-proxy service. Moreover, it associates all
its downlink interfaces and maintains their propagated multicast group
information.
Up to 32 proxy services can be configured using this command. The interface
number with the IGMP Proxy enabled is limited by the multicast interface number
supported by the device. Upon the receipt of query message, the proxy-service
interface responds accordingly based on the member information that it maintains
from the interfaces with mroute-proxy configured. Consequently, configuring
proxy-service on an interface equals to performing host behaviors rather than
