[. . . ] (Range: 2-10, Default: 2) IGMP Query Interval -- Sets the frequency at which the switch sends IGMP host-query messages. (Range: 60-125 seconds, Default: 125) IGMP Report Delay -- Sets the time between receiving an IGMP Report for an IP multicast address on a port before the switch sends an IGMP Query out of that port and removes the entry from its list. (Range: 5-30 seconds, Default: 10) IGMP Query Timeout -- The time the switch waits after the previous querier stops before it considers the router port (i. e. , the interface which had been receiving query packets) to have expired. (Range: 300-500 seconds, Default: 300) · · · · · 3-166 MULTICAST FILTERING · IGMP Version -- Sets the protocol version for compatibility with other devices on the network. Some attributes are only enabled for IGMPv2, including IGMP Report Delay and IGMP Query Timeout. Configuring Internet Group Management Protocol CLI ­ This example modifies the settings for multicast filtering, and then displays the current status.

These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch. You can use the Multicast Router Port Information page to display the ports on this switch attached to a neighboring multicast router/switch for each VLAN ID. Command Attributes · · VLAN ID ­ ID of configured VLAN (1-4094). Multicast Router List ­ Multicast routers dynamically discovered by this switch or those that are statically assigned to an interface on this switch. Web ­ Click IGMP Snooping, Multicast Router Port Information. Select the required VLAN ID from the scroll-down list to display the associated multicast routers. Figure 3-77. Mapping Multicast Switch Ports to VLANs 3-168 MULTICAST FILTERING CLI ­ This example shows that Port 11 has been statically configured as a port attached to a multicast router. Console#show ip igmp snooping mrouter vlan 1 VLAN M'cast Router Port Type ---- ------------------ ------1 Eth 1/11 Static 4-229 Specifying Static Interfaces for a Multicast Router Depending on your network connections, IGMP snooping may not always be able to locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/ switch connected over the network to an interface (port or trunk) on your switch, you can manually configure the interface (and a specified VLAN) to join all the current multicast groups supported by the attached router. This can ensure that multicast traffic is passed to all the appropriate interfaces within the switch. Command Attributes · · · Interface ­ Activates the Port or Trunk scroll down list. VLAN ID ­ Selects the VLAN to propagate all multicast traffic coming from the attached multicast router. Port or Trunk ­ Specifies the interface attached to a multicast router. Web ­ Click IGMP Snooping, Static Multicast Router Port Configuration. Specify the interfaces attached to a multicast router, indicate the VLAN which will forward all the corresponding multicast traffic, and then click Add. After you have finished adding interfaces to the list, click Apply. Figure 3-78. Static Multicast Router Port Configuration 3-169 CONFIGURING THE SWITCH CLI ­ This example configures port 11 as a multicast router port within VLAN 1.

Command Attribute · · · VLAN ID ­ Selects the VLAN for which to display port members. Multicast IP Address ­ The IP address for a specific multicast service. Multicast Group Port List ­ Shows the interfaces that have already been assigned to the selected VLAN to propagate a specific multicast service. 3-170 MULTICAST FILTERING Web ­ Click IGMP Snooping, IP Multicast Registration Table. [. . . ] Data traffic on downlink ports can only be forwarded to, and from, uplink ports. Remote Authentication Dial-in User Service (RADIUS) RADIUS is a logon authentication protocol that uses software running on a central server to control access to RADIUS-compliant devices on the network. Remote Monitoring (RMON) RMON provides comprehensive network monitoring capabilities. It eliminates the polling required in standard SNMP, and can set alarms on a variety of traffic conditions, including specific error types. [. . . ]
