Configure IGMP snooping and multicast on ports that have been statically assigned to an EPG to enable processing of IGMP protocol traffic.

This task enables IGMP snooping and multicast functionality on statically assigned ports to allow processing of IGMP protocol traffic sent to associated multicast IP addresses.

You can enable IGMP snooping and multicast on ports that have been statically assigned to an EPG. Afterwards you can create and assign access groups of users that are permitted or denied access to the IGMP snooping and multicast traffic enabled on those ports.

Before you begin

Before you begin to enable IGMP snooping and multicast for an EPG, complete the following tasks:

  • Identify the interfaces to enable this function and statically assign them to that EPG

    Note
    For details on static port assignment, see Deploying an EPG on a Specific Node or Port Using the GUI in the Cisco APIC Layer 2 Networking Configuration Guide.

  • Identify the IP addresses that you want to be recipients of IGMP snooping and multicast traffic.

Follow these steps to enable IGMP snooping and multicast on static ports using the GUI:

Procedure

  1. Click Tenant > tenant_name > Application Profiles > application_name > Application EPGs > epg_name > Static Ports.

    Navigating to this spot displays all the ports you have statically assigned to the target EPG.

  2. Click the port to which you intend to statically assign group members for IGMP snooping.

    This action displays the Static Path page.

  3. On the IGMP Snoop Static Group table, click + to add an IGMP Snoop Address Group entry.

    Adding an IGMP Snoop Address Group entry associates the target static port with a specified multicast IP address and enables it to process the IGMP snoop traffic received at that address.

    1. In the Group Address field, enter the multicast IP address to associate with his interface and this EPG.
    2. In the Source Address field enter the IP address of the source to the multicast stream, if applicable.
    3. Click Submit.

    When configuration is complete, the target interface is enabled to process IGMP Snooping protocol traffic sent to its associated multicast IP address.

    Note

    You can repeat this step to associate additional multicast addresses with the target static port.

  4. Click Submit.

The target interface is now enabled to process IGMP snooping protocol traffic sent to its associated multicast IP addresses. Multiple multicast addresses can be associated with the same static port as needed.
