Chapter 13 IGMP/MLD Table 70 Network Setting > IGMP/MLD (continued) LABEL DESCRIPTION Query Response Enter the maximum number of seconds the Zyxel Device can wait for receiving a General Query Interval message. Multicast routers use general queries to learn which multicast groups have members. Last Member Query Interval Enter the maximum number of seconds the Zyxel Device can wait for receiving a response to a Group-Specific Query message. Multicast routers use group-specific queries to learn whether any member remains in a specific multicast group. Robustness Value Enter the number of times (1~7) the Zyxel Device can resend a packet if packet loss occurs due to network congestion. Maximum Multicast Groups Enter a number to limit the number of multicast groups an interface on the Zyxel Device is allowed to join. Once a multicast member is registered in the specified number of multicast groups, any new IGMP or MLD join report frames are dropped by the interface. Maximum Multicast Data Sources(for IGMPv3) Enter a number to limit the number of multicast data sources (1-24) a multicast group is allowed to have. Note: The setting only works for IGMPv3 and MLDv2. Maximum Multicast Group Members Enter a number to limit the number of multicast members a multicast group can have. Fast Leave Enable Select this option to set the Zyxel Device to remove a port from the multicast tree immediately (without sending an IGMP or MLD membership query message) once it receives an IGMP or MLD leave message. This is helpful if a user wants to quickly change a TV channel (multicast group change) especially for IPTV applications. LAN to LAN Select this to enable LAN to LAN IGMP snooping capability. (Intra LAN) Multicast Enable Membership Join Immediate (IPTV) Select this to have the Zyxel Device add a host to a multicast group immediately once the Zyxel Device receives an IGMP or MLD join message. Cancel Click Cancel to restore your previously saved settings. Apply Click Apply to save your changes back to the Zyxel Device. PX7511-B0 User's Guide 188
