xStack® DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch (1- 25) Version (1-3) Host Timeout (1-16711450 sec) Route Timeout (1-16711450 sec) Leave Timer (1-6375 sec) Querier State Querier Router Behavior State Fast Leave Report Suppression Receive Query Count Send Query Count Data Driven Learning State Data Driven Learning Aged Out Data Driven Group Expiry Time (1-65535) messages, including those sent in response to leave group messages. Default = 1. Configure the IGMP version of the query packet which will be sent by the router. This is the maximum amount of time in seconds allowed for a host to continue membership in a multicast group without the Switch receiving a host membership report. Default = 260. This is the maximum amount of time in seconds a route is kept in the forwarding table without receiving a membership report. Default = 260. This specifies the maximum amount of time in seconds between the Switch receiving a leave group message from a host, and the Switch issuing a group membership query. If no response to the membership query is received before the Leave Timer expires, the (multicast) forwarding entry for that host is deleted. The default setting is 2 seconds. Choose Enabled to enable transmitting IGMP Query packets or Disabled to disable. The default is Disabled. This read-only field describes the current querier state of the Switch, whether Querier, which will send out Multicast Listener Query Messages to links, or NonQuerier, which will not send out Multicast Listener Query Messages. Select Enabled to implement IGMP Snooping. This field is Disabled by default. The Fast Leave option may be Enabled or Disabled (default). This allows an interface to be pruned without sending group-specific queries. This parameter allows the user to enable the Report Suppression function. When IGMP report suppression is Enabled, the Switch sends the first IGMP report from all hosts for a group to all the multicast routers. The Switch does not send the remaining IGMP reports for the group to the multicast routers. If the multicast router query includes requests only for IGMPv1 and IGMPv2 reports, the Switch forwards only the first IGMPv1 or IGMPv2 report from all hosts for a group to all the multicast routers. If the multicast router query also includes requests for IGMPv3 reports, the Switch forwards all IGMPv3 reports for a group to the multicast devices. The default is Disabled. The field appears when selecting State as Enabled. This is used to show the number of IGMP query packets DUT received from specified VLAN when the IGMP snooping is enabled. The field appears when selecting State as Enabled. This is used to show the number of IGMP query packets DUT sent from specified VLAN when the IGMP snooping is enabled. Select Enabled or Disabled for data driven learning status. Use the pull-down menu to enable or disable the aging out of the entry. Specify the data driven group lifetime in seconds. This parameter is valid only when Data Driven Learning Aged Out is Enabled. Click Apply to implement the new settings. Click the Show All IGMP Snooping Entries link to return to the IGMP Snooping Settings window. Router Port Settings 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. 166
