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 the commands supported by the first interface are available. The first
interface is specified with the interface range command.
•You cannot enter the view of some interfaces by using the interface interface-type
{ interface-number | interface-number.subnumber } command, for example, BRI 2/1/1:1. Do not
configure any of these interfaces as the first interface in the interface range.
•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.
•No limit is set on the maximum number of interfaces in an interface range. The more interfaces in
an interface range, the longer the command execution time.
•The maximum number of interface range names is only limited by the system resources. To
guarantee bulk interface configuration performance, HP recommends that you configure fewer than
1000 interface range names.
•If a command fails to take effect on the first interface in an interface range, the command does not
take effect on any other member interfaces. Failure to apply a command on a non-first member
interface does not affect the application of the command on the other member interfaces.
Configuration procedure
To bulk configure interfaces:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface range
view.
•interface range { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5>
•interface range name name
[ interface { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5> ]
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.

5. (Optional.) Verify the

Configuring Ethernet interfaces
In this chapter, "MSR1000" refers to MSR1002-4. "MSR2000" refers to MSR2003, MSR2004-24,
MSR2004-48. "MSR3000" collectively refers to MSR3012, MSR3024, MSR3044, MSR3064.
"MSR4000" collectively refers to MSR4060 and MSR4080.
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. By creating subinterfaces on a Layer 3 Ethernet
interface, you enable the interface to carry packets for multiple VLANs. For 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 and Layer 3 Ethernet interfaces or subinterfaces.
For more information about the settings specific to Layer 2 and Layer 3 Ethernet interfaces or
subinterfaces, see "Configuring a Layer 2 Ethernet interface" and "Configuring a Layer 3 Ethernet
interface or subinterface."
Configuring a combo interface
A combo interface is a logical interface that physically comprises one fiber port and one copper port.
The two ports share one forwarding channel and one interface view, so 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 and identify the two physical interfaces that
compose each combo interface according to the marks on the device panel.
•Use the display interface command to determine which port (fiber or copper) of the combo
interface is active. If the current port is the copper port, the output includes "Media type is twisted
pair, Port hardware type is 1000_BASE_T." If the current port is the fiber port, the output does not
include this information. You can also use the display this command in the view of the combo
interface to view the combo interface configuration. If the combo enable fiber command exists, the
fiber port is active. If the command does not exist, the copper port is active.

Changing the active port of a combo interface
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface view. interface interface-type
interface-number N/A
3. Activate the copper combo
port or fiber combo port. combo enable {copper |fiber }By default, the copper combo port
is active.
Configuring basic settings of an Ethernet interface or
subinterface
You can set an Ethernet interface to operate in one of the following duplex modes:
•Full-duplex mode (full)—Interfaces can send and receive packets simultaneously.
•Half-duplex mode (half)—Interfaces cannot send and receive packets simultaneously.
•Autonegotiation mode (auto)—Interfaces negotiate a duplex mode with their peers.
You can set the speed of an Ethernet interface or enable it to automatically negotiate a speed with its
peer.
Configuring an Ethernet interface
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface
view.
interface interface-type
interface-number N/A
3. Set the interface
description. description text
The default setting is in the format of
interface-name Interface. For example,
GigabitEthernet2/0/1 Interface.
4. Set the duplex mode of
the Ethernet interface. duplex { auto | full | half }
The default setting is full for 10-GE
interfaces and auto for other Ethernet
interfaces.
Fiber ports do not support the half
keyword.
5. Set the port speed. speed { 10 | 100 |1000 |
10000 | auto }
By default, the auto keyword is used.
Support for the keywords of the command
depends on the interface type. For more
information, see Interface Command
References.
6. Configure the expected
bandwidth of the
interface.
bandwidth bandwidth-value
By default, the expected bandwidth (in
kbps) is the interface baud rate divided by
1000.
7. Restore the default
settings for the Ethernet
interface.

Step Command Remarks
8. Bring up the Ethernet
interface. undo shutdown By default, the Ethernet interface is down.

Remarks
1. Enter system view. system-view N/A
2. Create an Ethernet
subinterface.

3. Set the interface description. description text
The default setting is
interface-name Interface. For
example, GigabitEthernet2/0/1.1
Interface.
4. Restore the default settings for
the Ethernet subinterface. default N/A
5. Configure the expected
bandwidth of the interface. bandwidth bandwidth-value
By default, the expected
bandwidth (in kbps) is the interface
baud rate divided by 1000.
6. Bring up the Ethernet
subinterface. undo shutdown By default, the Ethernet
subinterface is down.
For the local and remote Ethernet subinterfaces to transmit traffic correctly, configure them with the same
subinterface number and VLAN ID.
