DXS-3326GSR Gigabit Layer 3 Switch
messages indicating that there are no multicast members on their respective branches. PIM-DM then removes these
branches (‘prunes’ them) from the multicast delivery tree.
Because a member of a pruned branch of a multicast delivery tree may want to join a multicast delivery group (at some
point in the future), the protocol periodically removes the ‘prune’ information from its database and floods multicast
messages to all interfaces on that branch. The interval for removing ‘prune’ information is the Join/Prune Interval.
PIM-DM Global Settings
To enable PIM-DM globally on the Switch, go to Configuration > IP Multicast Routing Protocol > PIM > PIM-DM
Configuration. This will give the user access to the following screen:

PIM-DM Interface Settings
To view the first PIM-DM Interface Settings window, open the IP Multicast Routing Protocol folder under
Configuration and click PIM-DM Interface Settings. This window allows the PIM-DM to be configured for each IP
interface defined on the Switch. Each IP interface configured on the Switch is displayed in the below first PIM-DM
Interface Settings window.
