Figure 6: Static and Dynamic IGMP Interfaces
You configure static IGMP interfaces by using software such as the CLI or an SNMP
application; you configure dynamic IGMP interfaces by using a profile. A profile constitutes
a set of attributes for an interface; a profile for dynamic IGMP interfaces contains attributes
for configuring all the layers in the interface.
You define a profile by using the same CLI commands that you use to configure a static
IGMP interface; however, the mode in which you use the commands differs. Use the
commands in Interface Configuration mode to configure a static IGMP interface and in
Profile Configuration mode to define a profile.
When you have defined a profile, you can apply it to an interface or a group of interfaces.
Profiles provide an efficient method of creating and managing large numbers of dynamic
interfaces. For detailed information about creating and assigning profiles, see Configuring
Dynamic Interfaces in the JunosE Link Layer Configuration Guide. When you create a profile
for dynamic IGMP interfaces, specify attributes for configuring all layers in the interface.
You use the following IGMP commands to configure a static IGMP interface. You also
use these commands to define the attributes for the IGMP layer when you create a profile
for dynamic IGMP interfaces:
