Implementing MLD Group Limits Per-interface and global MLD limits operate independently of each other. Both per-interface and global MLD limits can be configured on the same switch. The number of MLD limits, globally or per interface, is not configured by default; the limits must be configured by the user. A membership report that exceeds either the per-interface or the global state limit is ignored. Implementing IPv6 Multicast Implementing MLD Group Limits Command or Action Purpose Device(config-if)# ipv6 mld query-timeout 130 Step 8 exit Example: Device(config-if)# exit Enter this command twice to exit interface configuration mode and enter privileged EXEC mode.
Step 9 show ipv6 mld groups [link-local] [ group-name | group-address] [interface-type interface-number] [detail | explicit] Example: Device# show ipv6 mld groups GigabitEthernet 1/0/1 Displays the multicast groups that are directly connected to the switch and that were learned through MLD. Step 10 show ipv6 mld groups summary Example: Device# show ipv6 mld groups summary Displays the number of (*, G) and (S, G) membership reports present in the MLD cache. Step 11 show ipv6 mld interface [type number] Example: Device# show ipv6 mld interface GigabitEthernet 1/0/1 Displays multicast-related information about an interface.
Step 12 debug ipv6 mld [group-name | group-address | interface-type] Example: Device# debug ipv6 mld Enables debugging on MLD protocol activity. Step 13 debug ipv6 mld explicit [group-name | group-address Example: Device# debug ipv6 mld explicit Displays information related to the explicit tracking of hosts. Step 14 copy running-config startup-config (Optional) Save your entries in the configuration file. Implementing IPv6 Multicast 11
