Video Pixelation is observed when running PIM-Dense on EXOS device
some streams affected but not all
some groups not pruned
When there is a high amount of multicast traffic the tables can become over loaded and some addresses do not get stored properly. Therefore this traffic is repeatedly sent to the CPU for slow path forwarding which can create problems for streams susceptible to latency.
Issue the following command:
configure forwarding ipmc compression group-table
this will enable compression of entries in the IP multicast group table to facilitate improved IP multicast scaling
Ideally, the preferred method is to identify the multicast traffic and determine if it is necessary.
