PIM-DM (Dense Mode) on the 5300xl Switches 
Displaying PIM Data and Configuration Settings on the Series 5300xl Switches 
DownStream Interfaces: 
–  VLAN:  Lists the VID of the destination VLAN on the next-
hop multicast router. 
–  Prune Reason: Identifies the reason for pruning the flow to the 
indicated VLAN: 
• 
• 
• 
Prune: A neighbor multicast router has sent a prune 
request. 
Assert: Another multicast router connected to the 
same VLAN has been elected to provide the path for 
the specified multicast group traffic. 
Other: Used where the VLAN is in the pruned state 
for any reason other than the above two reasons 
(such as no neighbors exist and no directly con-
nected hosts have done joins). 
This example displays the MRT 
data on the first of the two 
multicast groups shown in figure 
5-13 on page 5-31.
