Ethernet Port Configuration 45
By default, port loopback detection and the loopback detection control function
on trunk and hybrid ports are disabled. The detection interval is 30 seconds, and
the system detects the default VLAN on the trunk and hybrid ports.
Copying Port Configuration to Other Ports
To keep the configuration of other ports consistent with a specified port, you can
copy the configuration of that specified port to other ports. The configuration may
include: STP setting, QoS setting, VLAN setting, port setting, and LACP setting.
The STP setting includes STP enabling/disabling, link attribute (point-to-point or
not), STP priority, path cost, max transmission speed, loop protection, root
protection, edge port or not. The QoS setting includes traffic limiting, priority
marking, default 802.1p priority, bandwidth assurance, congestion avoidance,
traffic redirection, and traffic statistics. The VLAN setting includes permitted VLAN
types, and default VLAN ID. The port setting includes port link type, port speed,
and duplex mode. LACP setting includes LACP enabling/disabling.
Perform the following configuration in System View.
Note that if the copy source is an aggregation group, take the port with minimum
ID as the source; if the copy destination is an aggregation group, make the
configurations of all group member ports identical with that of the source.

After the above configuration, enter the
display
command in any view to display
the running of the Ethernet port configuration, and to verify the effect of the
configuration.
Enter the
