Usage Guidelines

Usage Scenario

If static is specified, the command displays only information about MLD groups that hosts statically join. Otherwise, the command displays information about all MLD groups that hosts join.

If both static and verbose are specified, the command displays detailed information about MLD groups that hosts statically join.

Example

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