Ethernet Port Configuration 171
Copying the
Configuration of a Port
to Other Ports
To make some other ports have the same configuration as that of a specific port,
you can copy the configuration of the specific port to the ports.
Specifically, the following types of port configuration can be copied from one port
to other ports: VLAN configuration, protocol-based VLAN configuration, LACP
configuration, QoS configuration, STP configuration and initial port configuration.
The other configurations cannot be copied temporarily.
■ VLAN configuration: includes IDs of the VLANs allowed on the port and the
default VLAN ID of the port;
■ Protocol-based VLAN configuration: includes IDs and indexes of the
protocol-based VLANs allowed on the port;
■ Link aggregation control protocol (LACP) configuration: includes LACP
enable/disable status;
■ QoS configuration: includes rate limit, port priority, and default 802.1p priority
on the port;
■ STP configuration: includes STP enable/disable status on the port, link attribute
on the port (point-to-point or non-point-to-point), STP priority, path cost,
packet transmission rate limit, whether loop protection is enabled, whether
root protection is enabled, and whether the port is an edge port;
■ Port configuration: includes link type of the port, port rate and duplex mode.
n
■ If you specify a source aggregation group ID, the system will use the port with
the smallest port number in the aggregation group as the source.
■ If you specify a destination aggregation group ID, the configuration of the
source port will be copied to all ports in the aggregation group and all ports in
the group will have the same configuration as that of the source port.
Configuring Loopback
Detection for a Port
Loopback detection is used to monitor if loopback occurs on a switch port.
Add the current trunk port to
a specified VLAN
port trunk permit vlan {
vlan-id-list | all }
