Property | Description |
|---|---|
| igmp-snooping (yes | no; Default: no) | Enables IGMP and MLD snooping. |
| igmp-version (2 | 3; Default: 2) | Selects the IGMP version in which IGMP membership queries will be generated when the bridge interface is acting as an IGMP querier. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |
| last-member-interval (time; Default: 1s) | When the last client on the bridge port unsubscribes to a multicast group and the bridge is acting as an active querier, the bridge will send group-specific IGMP/MLD query, to make sure that no other client is still subscribed. The setting changes the response time for these queries. In case no membership reports are received in a certain time period ( If the bridge port is configured with fast-leave, the multicast group is removed right away without sending any queries. This property only has an effect when |
| last-member-query-count (integer: 0..4294967295; Default: 2) | How many times should last-member-interval pass until the IGMP/MLD snooping bridge stops forwarding a certain multicast stream. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |
| membership-interval (time; Default: 4m20s) | The amount of time after an entry in the Multicast Database (MDB) is removed if no IGMP/MLD membership reports are received on a bridge port. This property only has an effect when igmp-snooping is set to yes. |
| mld-version (1 | 2; Default: 1) | Selects the MLD version in which MLD membership queries will be generated, when the bridge interface is acting as an MLD querier. This property only has an effect when the bridge has an active IPv6 address, igmp-snooping and multicast-querier is set to yes. |
| multicast-querier (yes | no; Default: no) | Multicast querier generates periodic IGMP/MLD general membership queries to which all IGMP/MLD capable devices respond with an IGMP/MLD membership report, usually a PIM (multicast) router or IGMP proxy generates these queries. By using this property you can make an IGMP/MLD snooping enabled bridge to generate IGMP/MLD general membership queries. This property should be used whenever there is no active querier (PIM router or IGMP proxy) in a Layer2 network. Without a multicast querier in a Layer2 network, the Multicast Database (MDB) is not being updated, the learned entries will timeout and IGMP/MLD snooping will not function properly. Only untagged IGMP/MLD general membership queries are generated, IGMP queries are sent with IPv4 0.0.0.0 source address, MLD queries are sent with IPv6 link-local address of the bridge interface. The bridge will not send queries if an external IGMP/MLD querier is detected (see the monitoring values This property only has an effect when |
| multicast-router (disabled | permanent | temporary-query; Default: temporary-query) | A multicast router port is a port where a multicast router or querier is connected. On this port, unregistered multicast streams and IGMP/MLD membership reports will be sent. This setting changes the state of the multicast router for a bridge interface itself. This property can be used to send IGMP/MLD membership reports and multicast traffic to the bridge interface for further multicast routing or proxying. This property only has an effect when igmp-snooping is set to yes.
|
| querier-interval (time; Default: 4m15s) | Changes the timeout period for detected querier and multicast-router ports. This property only has an effect when igmp-snooping is set to yes. |
| query-interval (time; Default: 2m5s) | Changes the interval on how often IGMP/MLD general membership queries are sent out when the bridge interface is acting as an IGMP/MLD querier. The interval takes place when the last startup query is sent. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |
| query-response-interval (time; Default: 10s) | The setting changes the response time for general IGMP/MLD queries when the bridge is active as an IGMP/MLD querier. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |
| startup-query-count (integer: 0..4294967295; Default: 2) | Specifies how many times general IGMP/MLD queries must be sent when bridge interface is enabled or active querier timeouts. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |
| startup-query-interval (time; Default: 31s250ms) | Specifies the interval between startup general IGMP/MLD queries. This property only has an effect when igmp-snooping and multicast-querier is set to yes. |

Property | Description |
|---|---|
| fast-leave (yes | no; Default: no) | Enables IGMP/MLD fast leave feature on the bridge port. The bridge will stop forwarding multicast traffic to a bridge port when an IGMP/MLD leave message is received. This property only has an effect when igmp-snooping is set to yes. |
| multicast-router (disabled | permanent | temporary-query; Default: temporary-query) | A multicast router port is a port where a multicast router or querier is connected. On this port, unregistered multicast streams and IGMP/MLD membership reports will be sent. This setting changes the state of the multicast router for bridge ports. This property can be used to send IGMP/MLD membership reports and multicast streams to certain bridge ports for further multicast routing or proxying. This property only has an effect when igmp-snooping is set to yes.
|
| unknown-multicast-flood (yes | no; Default: yes) | Changes the multicast flood option on bridge port, only controls the egress traffic. When enabled, the bridge allows flooding multicast packets to the specified bridge port, but when disabled, the bridge restricts multicast traffic from being flooded to the specified bridge port. The setting affects all multicast traffic, this includes non-IP, IPv4, IPv6 and the link-local multicast ranges (e.g. 224.0.0.0/24 and ff02::1). Note that when When using this setting together with |
