Verifying the Basic IGMP Configuration

Verifying the Basic IGMP Configuration

After configuring basic IGMP functions, verify the IGMP configuration, IGMP operating status, and information about IGMP group members.

Prerequisites

Basic IGMP functions have been configured.

Procedure

  • Run the display igmp [ vpn-instance vpn-instance-name | all-instance ] interface [ interface-type interface-number | up | down ] [ verbose ] command to check the configurations and operating status of IGMP on an interface.
  • Run the display igmp [ vpn-instance vpn-instance-name | all-instance ] group [ group-address | interface interface-type interface-number ] * [ static ] [ verbose ] command to check information about IGMP group members.

Example

Run the display igmp interface gigabitethernet 1/0/0 command to view the configurations and operating status of IGMP on GE 1/0/0.

<HUAWEI> display igmp interface gigabitethernet 1/0/0
Interface information of VPN-Instance: public net
 Gigabitethernet1/0/0(192.168.101.2):
   IGMP is enabled   
   Current IGMP version is 2   
   IGMP state: up   
   IGMP group policy: none   
   IGMP limit: -   
   Value of query interval for IGMP (negotiated): -   
   Value of query interval for IGMP (configured): 60 s   
   Value of other querier timeout for IGMP: 0 s   
   Value of maximum query response time for IGMP: 10 s   
   Querier for IGMP: 192.168.101.2 (this router)  
   Total 1 IGMP Group reported

Run the display igmp interface verbose command to view detailed IGMP information on an interface. The command output shows the Router-Alert option configuration and IGMP querier control parameters on GE 1/0/0. In this example, GE 1/0/0 has been configured to deny IGMP messages that do not carry the Router-Alert option.

<HUAWEI> display igmp interface verbose

   Value of other querier timeout for IGMP: 0 s
   Value of maximum query response time for IGMP: 10 s
   Value of last member query time: 2 s
   Value of last member query interval: 1 s
   Value of startup query interval: 15 s

   IGMP ipsec: enabled(sa-name: sa1)
  Total 2 IGMP Groups reported 

Run the display igmp group command. The command output shows information about the multicast groups that interfaces in the public network instance dynamically join.

<HUAWEI> display igmp group
