You can configure Multicast settings at the Interface level for each Edge model.
To enable and configure Multicast at the Interface level:
- In the Enterprise portal, go to Configure > Profiles > Device and select a target Edge model to configure Multicast.
- In the Interfaces Settings area, select the interface you want to enable Multicast and click the Edit button.
- In the Interface dialog box of the selected Edge:
- The Interface Enabled checkbox is enabled by default. If required, you can disable the Interface. When disabled, the Interface is not available for any communication.
- In the Capability drop-down menu, choose Routed to be able to use the Multicast settings. By default, the option Switched is selected for the Switch Port.
- In the Addressing Type drop-down menu, choose either DHCP, PPPoE, or Static.
- If applicable, select the WAN Overlay checkbox. By default, this option is enabled with Auto-Detect Overlay. You can choose the User Defined Overlay and configure the Overlay settings. For more information, see Configure Edge WAN Overlay Settings.
- If applicable, select the OSPF checkbox.
- In the Multicast section:
- If applicable, select the IGMP checkbox and select the only available option IGMP v2.
- If applicable, select the PIM checkbox and select the only available option PIM SM.
- Click the toggle advanced multicast settings link to set IGMP and PIM Timers.
- PIM Hello Timer - The default value is 30 seconds and the allowable range is 1 through 180 seconds.
- IGMP Host Query Interval: The default value is 125 seconds and the allowable range is 1 through 1800.
- IGMP Max Query Response Value: The default value is 100 deciseconds and the allowable range is 10 through 250 deciseconds.
- You must disable WAN Overlay to configure RADIUS Authentication. Select the checkbox to enable RADIUS Authentication on the Interface and add the MAC addresses that should not be forwarded to RADIUS for re-authentication. For more information, see Enabling RADIUS on a Routed Interface.
- If applicable, select the following checkboxes:
- Advertise - Select the checkbox to advertise the Interface to other branches in the network.
- ICMP Echo Response - Select the checkbox to enable the Interface to respond to ICMP echo messages. You can disable this option for the Interface, for security purposes.
- NAT Direct Traffic - Select the checkbox to apply NAT to the network traffic sent from the Interface.
- Underlay Accounting - This option is enabled by default. If a private WAN overlay is defined on the Interface, all underlay traffic traversing the interface will be counted against the measured rate of the WAN link to prevent over-subscription. If you do not want this behavior (for example, while using one-arm deployments), disable the option.
- Trusted Source - Select the checkbox to set the Interface as a trusted source.
- From the Reverse Path Forwarding drop-down menu, select one of the following options from the drop-down list:
Note: You can choose an option for Reverse Path Forwarding (RPF) only when you have enabled Trusted Source. RPF defaults to Specific mode when Trusted Source is disabled.
- Disabled – Allows incoming traffic even if there is no matching route in the route table.
- Specific – This option is selected by default, even when the Trusted Source option is disabled. The incoming traffic should match a specific return route on the incoming interface. If a specific match is not found, then the incoming packet is dropped. This is a commonly used mode on interfaces configured with public overlays and NAT.
- Loose – The incoming traffic should match any route(Connected/Static/Routed) in the routing table. This allows asymmetrical routing and is commonly used on interfaces that are configured without next hop.
- In the L2 Settings area, the Autonegotiate checkbox is enabled by default. The Auto-negotiation allows the port to communicate with the device on the other end of the link to determine the optimal duplex mode and speed for the connection.
- If Autonegotiate is unselected, enter the following details:
- Speed - This option is available only when Autonegotiate is disabled. Select the speed that the port has to communicate with other links. By default, 100 Mbps is selected.
- Duplex - This option is available only when Autonegotiate is disabled. Select the mode of the connection as Full duplex or Half duplex. By default, Full duplex is selected.
- MTU - The default MTU size for frames received and sent on all switch interfaces is 1500 bytes. You can change the MTU size for an Interface.
- Click Update to save the settings.
Note: Go to Monitor > Routing > Multicast tab, to view Multicast routing information. See Monitor Routing for more information.
