Parameters
interface interface-type interface-number [ to interface-type interface-number ]:
Specifies a port or port range.
zIf the to keyword is not specified, only one port is specified;
zIf the to keyword is specified, multiple contiguous ports are specified;
zThe interface-type argument represents the port type and the interface-number

both: Performs load sharing for both inbound traffic and outbound traffic on all the
member ports in the aggregation group.
Description
Use the link-aggregation command to add a series of ports to a new manual
