Add VLAN IP Multicast

This option allows you to add an IP-multicast filter. This is the IP group address whose multicast traffic will be filtered to create this VLAN.

Note: A VLAN for 224.0.0.1 (the all IP hosts address) is created during initialization and is used to configure IP multicast VLANs that are auto-created when an IGMP report frame is detected and the 224.0.0.1 VLAN is enabled.

Unlike other VLANs, IP Multicast VLANs can be automatically created and configured without user involvement. If auto-creation of IP Multicast VLANs is enabled, then the receipt of an IGMP Report frame (indicating a station's membership in an IP multicast group) causes an IP Multicast VLAN to be created for the group address indicated in the frame. Thus, IP Multicast groups can be configured on stations in the network without the need for VLAN configuration in the MSS bridge.

Auto-creation is enabled if an IP Multicast VLAN exists for the all IP hosts address of 224.0.0.1 and is enabled. If not already present, this VLAN is created and enabled during box initialization. It contains the initial port configuration, aging time, and MAC Address tracking status that will be applied to each new IP Multicast VLAN that is automatically created. To turn off auto-creation of IP Multicast VLANs, disable the VLAN for the 224.0.0.1 group address.

No IP Multicast VLANs can be auto-created or manually configured for the reserved multicast groups whose address is between 224.0.0.0 and 224.0.0.255, inclusive. This prevents potential problems in filtering frames necessary to several protocols that use these addresses.

  1. Enter the IP Multicast Address you want add.

    Valid Values: 224.0.1.0 - 239.255.255.255

    Default Value: none

  2. Select the Submit button.

  3. Select the Ports on which you want to configure the VLAN.

  4. Select the configuration of the port.

  5. Enter the Age (in minutes) of VLAN auto-Detection.

    This is the amount of time that an Auto-Detect port will remain in the forwarding state in the absence of traffic received from that port for this VLAN.

    Valid Values: 0 - 4294967295

    Default Value: 5000

  6. Click to Track active MAC addresses. This will cause source MAC addresses from transmissions on this VLAN to be saved. These learned addresses can be displayed using the Show Members command. Learned addresses will be aged out with the aging timer for this VLAN.

  7. Click to Enable this Filter.

  8. Enter the VLAN Name.

    Valid Values: Any string up to 32 characters in length

    Default Value: none
