Verifying the Basic MLD Configuration

Verifying the Basic MLD Configuration

After configuring basic MLD functions, verify the MLD configurations, MLD operating status, and information about MLD group members.

Prerequisites

Basic MLD functions have been configured.

Procedure

  • Run the display mld interface [ interface-type interface-number | up | down ] [ verbose ] command to view the configurations and operating status of MLD on an interface.
  • Run the display mld group [ ipv6-group-address | interface interface-type interface-number ] * [ static ] [ verbose ] command to check information about MLD group members.

Example

Run the display mld interface gigabitethernet 1/0/0 verbose command. The command output shows detailed MLD configurations on GE 1/0/0.

<HUAWEI> display mld interface gigabitethernet 1/0/0 verbose
