Copying Port
Configuration to Other
Ports
To keep the configuration of some other ports consistent with a specified port, you
can copy the configuration of the specified port to these ports.
The configuration may include:
■ VLAN settings: Includes the permitted VLAN types and default VLAN ID.
■ LACP settings: LACP enabled/disabled.
■ QoS settings: Includes traffic limiting, priority marking, default 802.1p priority,
bandwidth reservation, congestion avoidance, traffic direction, and traffic
statistics.,
■ STP settings: Includes STP enabling/disabling, link attribute (point-to-point or not),
STP priority, path cost, maximum transmission speed, loop protection, root
protection, and edge port or not.
■ Port setting: Includes port link type, port speed, and duplex mode.
If you specify the source aggregation group ID, the system uses the port with the
smallest port number in the aggregation group as the source.
If you specify the destination aggregation ID, the configuration of the source port will
be copied to all ports in the aggregation group.
Add the current hybrid
port into the specified
VLAN
port hybrid vlan vlan-id-list
{ tagged | untagged }
Optional
For a hybrid port, you can
configure to tag the packets
of specific VLANs, based on
which the packets of those
VLANs can be processed in
differently ways.
