Configuration prerequisites

To configure and use PGM on an 8000 Series switch, the switch must be running IP multicast with IGMP snooping and/or an IP multicast protocol such as DVMRP or PIM-SM. If PGM is configured without IP multicast enabled on a switch, PGM will not run and cannot be used.

To configure PGM on a switch, you need to perform the following steps:

  1. Configure and enable IP multicast on the switch, particularly on the interfaces where PGM is required.
  2. Enable PGM globally.
  3. Enable PGM on the required interfaces.
