[. . . ] Choose Querier to enable transmitting IGMP Query packets or NonQuerier to disable. Select Enabled to implement IGMP Snooping. This is Disabled by default. Max Response Time Robustness Variable Last Member Query Interval Host Timeout Route Timeout Leave Timer Querier State State Static Router Ports A static router port is a port that has a multicast router attached to it. Generally, this router would have a connection to a WAN or to the Internet. Establishing a router port will allow multicast packets coming from the router to be propagated through the network, as well as allowing multicast messages (IGMP) coming from the network to be propagated to the router. A router port has the following behavior: · · · All IGMP Report packets will be forwarded to the router port. IGMP queries (from the router port) will be flooded to all ports. All UDP multicast packets will be forwarded to the router port. Because routers do not send IGMP reports or implement IGMP snooping, a multicast router connected to the router port of the Layer 3 switch would not be able to receive UDP data streams unless the UDP multicast packets were all forwarded to the router port. 50 D-Link DGS-3224SR Layer 2 Gigabit Ethernet Switch A router port will be dynamically configured when IGMP query packets, RIPv2 multicast, DVMRP multicast, PIM-DM multicast packets are detected flowing into a port. Open the IGMP folder and the click on the Static Router Ports Entry link to open the Current Static Router Ports Entries page, as shown below. Figure 9-6. Current Static Router Ports Screen The Current Static Router Ports Entries page (shown above) displays all of the current entries to the Switch's static router port table. To add or modify an entry, click the Modify button. This will open the Static Router Ports Settings page, as shown below. Figure 9-7. Static Router Ports Settings Screen The following parameters can be set: Parameter VID (VLAN ID) VLAN Name Unit Member Ports Description This is the VLAN ID that, along with the VLAN name, identifies the VLAN where the multicast router is attached. This is the name of the VLAN where the multicast router is attached. This is the Unit ID of the switch in a switch stack for which you are creating an entry into the switch's static router port table. There are the ports on the switch that will have a multicast router attached to them. 51 D-Link DGS-3224SR Layer 2 Gigabit Ethernet Switch New IGMP Snooping Feature In the DGS-3224SR, the user may configure a forbidden portlist, whose members are not forced to become router ports. To activate this feature, please use the console (CLI). The CLI command will be: Config router_ports_forbidden To disp[lay the forbidden portlist, the CLI command will be: Show router_ports 52 D-Link DGS-3224SR Layer 2 Gigabit Ethernet Switch Section 10 Spanning Tree Protocol Configuration The switch supports 802. 1d Spanning Tree Protocol (STP) and 802. 1w Rapid Spanning Tree Protocol (RSTP). 802. 1d STP will be familiar to most networking professionals. However since 802. 1w RSTP has been recently introduced to D-Link managed Ethernet switches, a brief introduction to the technology is provided below followed by a description of how to set up 802. 1 d STP and 802. 1w RSTP. 802. 1w Rapid Spanning Tree The Switch implements two versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined by the IEE 802. 1w specification and a version compatible with the IEEE 802. 1d STP. RSTP can operate with legacy equipment implementing IEEE 802. 1d, however the advantages of using RSTP will be lost.
