CLI – This example configures profile number 19 by setting the access
mode to “permit” and then specifying a range of multicast groups that a
user can join. The current profile configuration is then displayed.
Configuring IGMP Filter and Throttling
Once you have configured IGMP profiles, you can then assign them to
interfaces on the switch. Also, you can set the IGMP throttling number to
limit the number of multicast groups an interface can join at the same time.
Command Usage
•
Only one profile can be assigned to an interface.
• An IGMP profile or throttling setting can be applied to a trunk
interface. When ports are configured as trunk members, the trunk uses
the settings applied to the first port member in the trunk.
• IGMP throttling sets a maximum number of multicast groups that a
port can join at the same time. When the maximum number of groups
is reached on a port, the switch can take one of two actions; either
“deny” or “replace.” If the action is set to deny, any new IGMP join
reports will be dropped. If the action is set to replace, the switch
randomly removes an existing group and replaces it with the new
multicast group..
Command Attributes
• Profile – Selects an existing profile number to assign to an interface.
• Max Multicast Groups (0-256) – Sets the maximum number of
multicast groups an interface can join at the same time.
