3Com 10014298 manual Copying a Port Configuration to Other Ports, Display and Debug Ethernet Port

Ethernet Port Overview 41

■To guarantee proper packet transmission, the default VLAN ID of local hybrid port or Trunk port should be identical to that of the hybrid port or Trunk port on the peer switch. The VLAN of hybrid port and trunk port is VLAN 1 by default. The access port is the VLAN to which it belongs.

Copying a 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. Port configuration involves the following settings:

■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.

■QoS setting — includes traffic limiting, priority marking, default 802.1p priority, bandwidth assurance, congestion avoidance, traffic redirection, traffic statistics.

■VLAN setting — includes permitted VLAN types, default VLAN ID.

■Port setting — includes port link type, port speed, duplex mode. LACP setting includes LACP enabling/disabling.

Perform the following configuration in system view.

Table 37 Copying a Port Configuration to Other Ports

Operation	Command
Copy port configuration to other ports	copy configuration source {
	interface-type interface-number
	interface-name
	aggregation-group agg-id }
	destination { interface_list [
	aggregation-group agg-id ]
	aggregation-group agg-id }

Note that if the copy source is an aggregation group, use the port with the lowest 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.

Displaying and Debugging Ethernet Ports

After configuration, execute the display command in all views to display the current configuration of Ethernet port parameters, and to verify the configuration.

Execute the reset command in user view to clear the statistics from the port.

Table 38 Display and Debug Ethernet Port

Operation	Command
Display all the information of the port	display interface {interface_type
	interface_type interface_num
	interface_name}
Display hybrid port or trunk port	display port { hybrid trunk }
Clear the statistics information of the port	reset counters interface
