To display dynamically learned multicast router information, perform one of these tasks in privileged mode: Task Command Display information on dynamically learned and show multicast router [mod_num/port_num] manually configured multicast router ports. [vlan_id] Display information only on those multicast show multicast router cgmp router ports learned dynamically using CGMP. [mod_num/port_num] [vlan_id] This example shows how to display information on all multicast router ports (the asterisk [*] next to the multicast router on port 3/1 indicates that the entry was configured manually): 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) This example shows how to display only those multicast router ports that were learned dynamically through CGMP: Console> (enable) show multicast router cgmp CGMP enabled IGMP disabled Port --------- 2/1 2/2 Vlan 99 255 Total Number of Entries = 3 '*' - Configured Console> (enable) 15-6 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 78-12647-02
