Bulk configuring interfaces

You can enter interface range view to bulk configure multiple interfaces with the same feature instead

of configuring them one by one. For example, you can execute the shutdown command in interface

range view to shut down a range of interfaces.

Configuration restrictions and guidelines

When you bulk configure interfaces in interface range view, follow these restrictions and guidelines:

•In interface range view, only commands supported by the first interface in the specified interface

list are available for configuration.

•Before you configure an interface as the first interface in an interface range, make sure you can

enter the view of the interface by using the interface interface-type { interface-number |

interface-number.subnumber } command.

•Do not assign both an aggregate interface and any of its member interfaces to an interface

range. Some commands, after being executed on both an aggregate interface and its member

interfaces, can break up the aggregation.

•Understand that the more interfaces you specify, the longer the command execution time.

•To guarantee bulk interface configuration performance, configure fewer than 1000 interface

range names.

•After a command is executed in interface range view, one of the following situations might

occur:

{The system displays an error message and stays in interface range view. It means that the

execution failed on one or multiple member interfaces.

−If the execution failed on the first member interface, the command is not executed on

any member interfaces.

−If the execution failed on a non-first member interface, the command takes effect on the

remaining member interfaces.

{The system returns to system view. It means that:

−The command is supported in both system view and interface view.

−The execution failed on a member interface in interface range view and succeeded in

system view.

−The command is not executed on the subsequent member interfaces.

You can use the display this command to verify the configuration in interface view of each

member interface. In addition, if the configuration in system view is not needed, use the

undo form of the command to remove the configuration.

Configuration procedure

Step Command Remarks

1. Enter system view. system-view N/A

Step Command Remarks

2. Enter interface range

view.

•interface range

{ interface-type

interface-number [ to

interface-type

interface-number ] } &<1-24>

•interface range name name

[ interface { interface-type

interface-number [ to

interface-type

interface-number ] } &<1-24> ]

By using the interface range name

command, you assign a name to an

interface range and can specify this

name rather than the interface range

to enter the interface range view.

3. (Optional.) Display

commands available for

the first interface in the

interface range.

Enter a question mark (?) at the

interface range prompt. N/A

4. Use available

commands to configure

the interfaces. Available commands depend on

the interface. N/A

5. (Optional.) Verify the

configuration. display this N/A

Displaying and maintaining bulk interface

configuration

Execute the display command in any view.

Task Command

Display information about the interface ranges

created by using the interface range name

command. display interface range [name name ]

Configuring Ethernet interfaces

Your device supports the following types of Ethernet interfaces:

•Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer

(Layer 2) to switch packets.

•Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer

(Layer 3) to route packets. You can assign an IP address to a Layer 3 Ethernet interface.

•Layer-configurable Ethernet interfaces—Physical Ethernet interfaces that can be configured

to operate in bridge mode as Layer 2 Ethernet interfaces or in route mode as Layer 3 Ethernet

interfaces.

•Layer 3 Ethernet subinterfaces—Logical interfaces operating at the network layer. You can

assign an IP address to a Layer 3 Ethernet subinterface. To enable a Layer 3 Ethernet interface

to transport packets for multiple VLANs, you must create Layer 3 subinterfaces on the Layer 3

Ethernet interface. For information about how a Layer 3 Ethernet subinterface sends and

receives VLAN-tagged packets, see Layer 2—LAN Switching Configuration Guide.

Configuring common Ethernet interface settings

This section describes the settings common to Layer 2 Ethernet interfaces, Layer 3 Ethernet

interfaces, and Layer 3 Ethernet subinterfaces. For more information about the settings specific to

Layer 3 Ethernet interfaces or subinterfaces, see "Configuring a Layer 3 Ethernet interface or

subinterface."

Ethernet interface naming conventions

In standalone mode, the Ethernet interfaces are named in the format of interface-type A/B/C, where:

•A: Specifies a card by its slot number.

•B: Specifies an interface module by its slot number on a card, which is fixed at 0.

•C: Specifies an interface number.

In IRF mode, the Ethernet interfaces are named in the format of interface-type A/B/C/D, where:

•A: Represents the member ID of the IRF member device, which can be 1 or 2.

•B: Specifies a card by its slot number.

•C: Specifies an interface module by its slot number on a card, which is fixed at 0.

•D: Specifies an interface number.

Configuring a combo interface

A combo interface is a logical interface that physically comprises one fiber combo port and one

copper combo port. The two ports share one forwarding channel and one interface view. As a result,

they cannot work simultaneously. When you activate one port, the other port is automatically

disabled. In the interface view, you can activate the fiber or copper combo port, and configure other

port attributes such as the interface rate and duplex mode.

Configuration prerequisites

Before you configure combo interfaces, complete the following tasks:

•Determine the combo interfaces on your device. Identify the two physical interfaces that belong

to each combo interface according to the marks on the device panel.
