Configuring Multicast Router Ports and Group Entries Chapter 15 Configuring Multicast Services Configuring Multicast Router Ports and Group Entries These sections describe how to manually specify multicast router ports and configure multicast group entries: • Specifying Multicast Router Ports, page 15-16 • Configuring Multicast Groups, page 15-16 • Clearing Multicast Router Ports, page 15-17 • Clearing Multicast Group Entries, page 15-17 Specifying Multicast Router Ports When you enable CGMP or GMRP, the switch automatically learns to which ports a multicast router is connected. However, if desired, you can manually specify multicast router ports. To statically define multicast router ports, perform this task in privileged mode: Step 1 Step 2 Task Manually specify a multicast router port. Verify the configuration. Command set multicast router mod_num/port_num show multicast router [mod_num/port_num] [vlan_id] This example shows how to define a multicast router port manually and verify the configuration (the asterisk [*] next to the multicast router on port 3/1 indicates that the entry was configured manually): Console> (enable) set multicast router 3/1 Port 3/1 added to multicast router port list. Console> (enable) show multicast router CGMP enabled IGMP disabled Port --------- 2/1 2/2 3/1 * Vlan 99 255 1 Total Number of Entries = 4 '*' - Configured Console> (enable) Configuring Multicast Groups To configure a multicast group statically, perform this task in privileged mode: Step 1 Step 2 Task Command Add one or more multicast MAC addresses to the set cam {static | permanent} multicast_mac CAM table. mod_num/port_num [vlan] Verify the multicast group configuration. show multicast group [mac_addr] [vlan_id] 15-16 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 78-12647-02
