The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Multicast is the delivery of information to multiple destinations simultaneously from a single source. Multicast frames from a registered Multicast group will only be sent to other ports that are registered to the same Multicast group. An Unregistered Multicast group has a set of ports that are not registered on the switch. Multicast frames from an unregistered multicast group are forwarded to all ports on the switch, but the ports can be configured either to receive or to filter the unregistered multicast frames.
The objective of this document is to show you how to configure unregistered multicast on Sx500 Series Stackable Switches.
• Sx500 Series Stackable Switches
Step 1. Log in to the web configuration utility and choose Multicast > Unregistered Multicast. The Unregistered Multicast page opens:
Step 2. Choose the desired interface type from the Filter: Interface Type Equals To drop-down list for which unregistered multicast frames are to be configured. The drop-down list contains the following interface types:
• Port — Denotes the individual port of units of the switch.
• LAG — Denotes the Link Aggregation Group (LAG) of the switch. A LAG contains the set of ports. The configuration of unregistered multicast is made to the LAG that ensures all the ports within LAG are configured.
Step 3. Click Go to choose the selected interface. If LAG is chosen as the interface type, skip Step 5.
Step 4. If Port is chosen from the Filter: Interface Type Equals To drop-down list, click one of the following radio buttons corresponding to that port:
• Forwarding — Forwards the unregistered multicast frames to that port.
• Filtering — Discards the unregistered multicast frames from that port.
Step 5. If LAG is chosen from the Filter: Interface Type Equals To drop-down list, click one of the following radio buttons corresponding to that LAG:
• Forwarding — Forwards the unregistered multicast frames to that LAG.
• Filtering — Discards the unregistered multicast frames from that LAG.
Step 6. Click Apply to save the settings.
