Enabling Source Specific Multicast (SSM) globally

To enable SSM globally:

  1. From the Device Manager menu bar, choose IP Routing > PIM.
    2. The PIM dialog box opens with the Globals tab displayed.

  2. Click Mode: ssm (source specific multicast).
  3. Click Enable.
  4. Click Apply.
    5. An information message pops up to remind you that traffic will not stop immediately.
  5. Click Yes to continue.


    6. Note Note: After you enable PIM in SSM mode, the IGMP parameters take effect. To take full advantage of SSM, enable IGMPv3 if hosts attached to the switch are running IGMPv3 or configuring the SSM table.

    For information, refer to "Internet Group Management Protocol (IGMP)."
