Usage Guidelines

Usage Scenario

When a large amount of information is output, the display debugging mld command can be used to view information about the enabled MLD debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging igmp command can be used to view information about the enabled igmp debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging mvpnv6 command can be used to view information about the enabled ipv6 ng mvpn debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging pim command can be used to view information about the enabled PIM debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging md command can be used to view information about the enabled MD debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging msdp command can be used to view information about the enabled MSDP debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging pim6 command can be used to view information about the enabled PIM IPv6 debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, the display debugging igmp command can be used to view information about the enabled IGMP debugging functions. Based on the command output, you can disable some unnecessary debugging functions to minimize the debugging information output.

When a large amount of information is output, run the display debugging mvpn command to check the NG MVPN debugging functions that have been enabled. Then you can disable some unnecessary debugging functions to minimize the debugging information output.

Example

The actual command output varies according to the device. The command output here is only an example.
