An Unregistered Multicast group has a set of ports that are not registered on a switch. Multicast frames from an unregistered multicast group are forwarded to all ports on the switch, but the ports can be configured to either receive or to filter the unregistered multicast frames.
The objective of this document is to show you how to configure Unregistered Multicast on SFE/SGE Managed Switches.
• SFE/SGE Managed Switches
Unregistered Multicast Configuration
Step 1. Log into the switch configuration utility to choose Bridging > Multicast > Unregistered Multicast. The Unregistered Multicastpage opens:
Step 2. Click the Ports or LAGs radio button to bring up a list of interfaces on it.
Step 3. Click Edit. The Edit Unregistered Multicast window appears:
The information displayed is defined as follows:
• Interface — Specifies the port or EtherChannel chosen by the user to modify.
Step 4. Choose the status of the interface from the Interface Status drop-down list.
• Forwarding — Unregistered multicast frames are forwarded to the VLAN interface.
• Filtering — Enables filtering of the unregistered multicast frames to the VLAN interface. It rejects the frames on the selected interface and that interface does not receive unregistered multicast frames.
Step 5. Click Apply.
Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file. See Copy Configuration File on SFE/SGE Series Managed Switches for more information on how to do this.
