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 Router ports are ports that are used to connect to a multicast router. Multicast router port numbers are included on the switch when it forwards the multicast streams and Internet Group Management Protocol / Multicast Listener Discovery (IGMP/MLD) registration messages. This is essential for the multicast router to forward multicast streams and forward registration messages to other subnets.
This article explains the configuration of Multicast Router ports on ESW2-350G switches.
Step 1. Log in to the web configuration utility and choose Multicast > Multicast Router Port. The Multicast Router Port page opens:
Step 2. Choose the ID of a VLAN from the VLAN ID drop-down list to the right of Filter to only show interfaces of that VLAN.
Step 3. Choose the IP version from the IP Version drop-down list to the right of Filter to filter the interfaces based on IP version.
Step 4. Choose the type of interface from the Interface Type drop-down list to the right of Filter in order to display either ports or LAGs.
• Port — Indicates the individual ports of the switch.
• LAG — Indicates the Link Aggregation Group (LAG) of the switch. A LAG consists of a set of ports. The Forward All multicast if configured as LAG makes all ports within the LAG to be configured.
Step 5. Click Go to show the interfaces matching the query criteria.
Step 6. For each port or LAG click the radio button that corresponds with its association type from the following options:
• Static — Multicast router port is statically configured.
• Dynamic — Multicast router port is dynamically configured by a MLD / IGMP query. Dynamic learning of Multicast Router ports can be enabled on the Multicast > IGMP Snooping page and the Multicast > MLD Snooping page.
Note: To configure MLD Snooping refer to the article Multicast Listener Discovery (MLD) Snooping Configuration on ESW2-350G Switches.
• Forbidden — Port should not be configured as a multicast router port, even if IGMP or MLD queries are received on this port. If the Auto Detect Multicast Router Ports option is enabled on this port, then the configuration is not successful.
• None — Port is not a Multicast router port at present.
Step 7. Click Apply.
