Parameter
interface_list: Specifies the Ethernet port list, including multiple Ethernet
ports. Expressed as
interface _list={ { interface_type interface_num |
interface_name } [ to { interface_type interface_num | interface_name } ]
}&<1-10>. For details about interface_type, interface_num and interface_name,
refer to the Port Command Manual. &<1-10> indicates the preceding parameter
can be input up to 10 times.
Description
