Overview
The HP V1910 Switch Series can be configured through the command line interface (CLI), web interface,
and SNMP/MIB. These configuration methods are suitable for different application scenarios.
The web interface supports all V1910 Switch Series configurations.
The CLI provides some configuration commands to facilitate your operation. To perform other
configurations not supported by the CLI, use the web interface.

Configuration through the web interface
Web-based network management operating
environment
HP provides the web-based network management function to facilitate the operations and maintenance on
HP’s network devices. Through this function, the administrator can visually manage and maintain network
devices through the web-based configuration interfaces.
a. Web-based network management operating environment
Logging in to the web interface
Default login information
The device is provided with the default Web login information. You can use the default information to log
in to the web interface.
1. The default web login information
Information needed at lo
g
in Default value
Username admin
Password None
IP address of the device (VLAN-interface 1)
Default IP address of the device, depending on the status
of the network where the device resides.
Table 1 The device is not connected to the network, or no DHCP server exists in the subnet where the device
resides
If the device is not connected to the network, or no DHCP server exists in the subnet where the device resides,
you can get the default IP address of the device on the label on the device, as shown in b. The default subnet
mask is 255.255.0.0.
b. Default IP address of the device
Table 2 A DHCP server exists in the subnet where the device resides
If a DHCP server exists in the subnet where the device resides, the device will dynamically obtain its default
IP address through the DHCP server. You can log in to the device through the console port, and execute the
summary command to view the information of its default IP address.
<Sysname> summary
Select menu option: Summary
IP Method: DHCP
IP address: 10.153.96.86
Subnet mask: 255.255.255.0
Default gateway: 0.0.0.0
<Omitted>
Example
Assuming that the default IP address of the device is 169.254.52.86, follow these steps to log in to the
device through the web interface.
Connect the device to a PC
Connect the GigabitEthernet interface of the device to a PC by using a crossover Ethernet cable (by default,
all interfaces belong to VLAN 1).
Configure an IP address for the PC and ensure that the PC and device can communicate with each
other properly.
Select an IP address for the PC from network segment 169.254.0.0/16 (except for the default IP address
of the device), for example, 169.254.52.86.
Open the browser, and input the login information.
On the PC, open the browser (IE 5.0 or later), type the IP address http://169.254.52.86 in the address bar,
and press Enter to enter the login page of the web interface, as shown in a. Input the username admin and
verification code, leave the password blank, and click Login.

CAUTION:
The PC where you configure the device is not necessarily a web-based network mana
A web-based network management terminal is a PC used to log in to the web interface and is required
to be reachable to the device.
After logging in to the web interface, you can select Device Users from the navigation tree, create
a new user, and select Wizard or Network VLAN interface to configure the IP address of the VLAN
interface acting as the management interface. For more information, see the corresponding
configuration guides of these modules.
If you click the verification code displayed on the web login page, you can get a new verification code.
Up to five users can concurrently log in to the device through the web interface.
Logging out of the web interface
Click Logout in the upper-right corner of the web interface, as shown in a to quit the web console.
The system does not save the current configuration automatically. Therefore, it is recommended to save the
current configuration before logout.
ement terminal.
Introduction to the web interface
The Web interface is composed of three parts: navigation tree, title area, and body area, as shown in a.
a. Web-based configuration interface
(1) Navigation tree (2) Body area (3) Title area
Navigation tree—Organizes the web-based NM functions as a navigation tree, where you can select
and configure functions as needed. The result is displayed in the body area.
Body area—Allows you to configure and display features.
Title area—Displays the path of the current configuration interface in the navigation tree; provides the
Help button to display the web related help information, and the Logout button to log out of the web
interface.

CAUTION:
The web network management functions not supported by the device are not displayed in the navi
tree.
Web user level
Web user levels, from low to high, are visitor, monitor, configure, and management. A user with a higher
level has all the operating rights of a user with a lower level.
Visitor—Users of this level can only use the network diagnostic tools ping and Trace Route. They can
neither access the device data nor configure the device.
Monitor—Users of this level can only access the device data but cannot configure the device.
Configure—Users of this level can access device data and configure the device, but they cannot
upgrade the host software, add/delete/modify users, or back up/restore configuration files.
Management—Users of this level can perform any operations to the device.

Configuration guidelines
The web console supports Microsoft Internet Explorer 6.0 SP2 and higher.
The web console does not support the Back, Next, Refresh buttons provided by the browser. Using
these buttons may result in abnormal display of web pages.
When the device is performing the spanning tree calculation, you cannot log in to or use the web
interface.
The Windows firewall limits the number of TCP connections, so when you use IE to log in to the web
interface, sometimes you may be unable to open the web interface. To avoid this problem, turn off the
Windows firewall before login.
If the software version of the device changes, when you log in to the device through the web interface,
delete the temporary Internet files of IE; otherwise, the web page content may not be displayed
correctly.

Configuration at the CLI
NOTE:
The HP V1910 Switch Series can be configured through the CLI, web interface, and SNMP/MIB,
among which the web interface supports all V1910 Switch Series configurations. These configuration
methods are suitable for different application scenarios. As a supplementary to the web interface, the
CLI provides some configuration commands to facilitate your operation, which are described in this
chapter. To perform other configurations not supported by the CLI, use the web interface.
You will enter user view directly after you log in to the device. Commands in the document are all
performed in user view.
Getting started with the CLI
As a supplementary to the web interface, the CLI provides some configuration commands to facilitate your
operation. For example, if you forget the IP address of VLAN-interface 1 and cannot log in to the device
through the web interface, you can connect the console port of the device to a PC, and reconfigure the IP
address of VLAN-interface 1 at the CLI.
This section describes using the CLI to manage the device.
Setting up the configuration environment
To set up the configuration environment, connect a terminal (a PC in this example) to the console port on the
switch with a console cable.
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to
the console port of the switch, and a DB-9 female connector at the other end for connecting to the serial port
on the console terminal.
a. Console cable
Use a console cable to connect a terminal device to the switch, as follows:
Table 3 Plug the DB-9 female connector to the serial port of the console terminal or PC.
Table 4 Connect the RJ-45 connector to the console port of the switch.
V
b. Network diagram for configuration environment setup
CAUTION:
erify the mark on the console port to ensure that you are connecting to the correct port.
NOTE:
The serial port on a PC does not support hot swapping. When you connect a PC to a powered-on
switch, connect the DB-9 connector of the console cable to the PC before connecting the RJ-45
connector to the switch.
When you disconnect a PC from a powered-on switch, disconnect the DB-9 connector of the console
cable from the PC after disconnecting the RJ-45 connector from the switch.
Setting terminal parameters
To configure and manage the switch, you must run a terminal emulator program on the console terminal, for
example, a PC. This section uses Windows XP HyperTerminal as an example.
The following are the required terminal settings:
Bits per second—38400
Data bits—8
Parity—None
Stop bits—1
Flow control—None
Emulation—VT100
Follow these steps to set terminal parameters, for example, on a Windows XP HyperTerminal:
Table 5 Select Start All Programs Accessories Communications HyperTerminal, and in the
Connection Description dialog box that appears, type the name of the new connection in the Name text
box and click OK.
17
b. Connection description of the HyperTerminal
Table 6 Select the serial port to be used from the Connect using drop-down list, and click OK.
c. Set the serial port used by the HyperTerminal connection
Table 7 Set Bits per second to 38400, Data bits to 8, Parity to None, Stop bits to 1, and Flow control to
None, and click OK.

IRF stack management
The HP V1910 IRF stack management feature enables you to configure and monitor a stack of connected HP
V1910 switches by logging in to one switch in the stack, as shown in a.
IMPORTANT:
The HP V1910 IRF stack management feature does not provide the functions of HP Intelligent Resilient
Framework (IRF) technology. To avoid confusion, IRF stack management is simply called stack
management in this document.
a. Network diagram for stack management
To set up a stack, you must log in to one switch to create the stack, and this switch becomes the master for
the stack. You then configure and monitor all other member switches on the master switch. The ports that
connect the stack member switches are called stack ports.

System time configuration
The system time module allows you to display and set the device system time on the web interface. The
device supports setting system time through manual configuration and automatic synchronization of NTP
server time.
An administrator can keep time synchronized among all the devices within a network by changing the
system clock on each device, however, this is a huge amount of workload and cannot guarantee the clock
precision.
Defined in RFC 1305, the Network Time Protocol (NTP) synchronizes timekeeping among distributed time
servers and clients. NTP allows quick clock synchronization within the entire network and ensures a high
clock precision so that the devices can provide diverse applications based on the consistent time.
Configuring system time
Select Device System Time from the navigation tree. The system time configuration page appears by
default, as shown in a. The current system time and clock status are displayed.

Source Interface
Set the source interface for an NTP message.
If you do not want the IP address of a certain interface on the local
device to become the destination address of response messages,
you can specify the source interface for NTP messages, so that the
source IP address in the NTP messages is the primary IP address of
this interface.
Key 1 Set an NTP authentication key.
The NTP authentication feature should be enabled for a system
running NTP in a network where there is a high security demand.
This feature enhances the network security by means of
client-server key authentication, which prohibits a client from
synchronizing with a device that has failed authentication.
You can set two authentication keys, each of which is composed of
a key ID and key string.
ID is the ID of a key.
Key string is a character string for MD5 authentication key.

Key ID

Only if the key provided by the server is the same with the
specified key will the device synchronize its time to the NTP server.
You can configure two NTP servers. The clients will choose the
optimal reference source.
IMPORTANT:
The IP address of an NTP server is a unicast address, and cannot be
a broadcast or a multicast address, or the IP address of the local
clock source.

Configuration guidelines
When configuring system time, note the following guidelines:
A device can act as a server to synchronize the clock of other devices only after its clock has been
synchronized. If the clock of a server has a stratum level higher than or equal to that of a client’s clock,
the client does not synchronize its clock to the server’s.
The synchronization process takes a period of time. Therefore, the clock status may be unsynchronized
after your configuration. In this case, you can refresh the page to view the clock status and system time
later on.

Item Description
Set the Medium Dependent Interface (MDI) mode of the port. Two types of
Ethernet cables can be used to connect Ethernet devices: crossover cable and
straight-through cable. To accommodate these two types of cables, an Ethernet
port can operate in one of the following three MDI modes: across, normal, and
auto.
An Ethernet port is composed of eight pins. By default, each pin has its
particular role. For example, pin 1 and pin 2 are used for transmitting signals;
pin 3 and pin 6 are used for receiving signals. You can change the pin roles
by setting the MDI mode.
For an Ethernet port in across mode, pin 1 and pin 2 are used for
transmitting signals; pin 3 and pin 6 are used for receiving signals. The pin
roles are cannot be changed.
For an Ethernet port in auto mode, the pin roles are decided through auto
negotiation.
MDI
For an Ethernet port in normal mode, the pin roles are changed. Pin 1 and
pin 2 are used for receiving signals; pin 3 and pin 6 are used for
transmitting signals.
To enable normal communication, you must connect the local transmit pins to
the remote receive pins. Therefore, you should configure the MDI mode
depending on the cable types.
HP does not recommend you to use the auto mode. The other two modes
are used only when the device cannot determine the cable type.
When straight-through cables are used, the local MDI mode must be
different from the remote MDI mode.
When crossover cables are used, the local MDI mode must be the same as
the remote MDI mode, or the MDI mode of at least one end must be set to
auto.
Flow Control
Power Save
Max MAC Count
IMPORTANT:
SFP optical ports do not support this feature.
Enable or disable flow control on the port.
With flow control enabled at both sides, when traffic congestion occurs on the
ingress port, the ingress port will send a Pause frame notifying the egress port
to temporarily suspend the sending of packets. The egress port is expected to
stop sending any new packet when it receives the Pause frame. In this way,
flow control helps to avoid dropping of packets.
IMPORTANT:
Flow control works only after it is enabled on both the ingress and egress ports.
Enable or disable auto power down on the port.
With auto power down enabled, when an Ethernet port does not receive any
packet for a certain period of time, it automatically enters the power save
mode and resumes its normal state upon the arrival of a packet.
By default, auto power down is disabled.
Set the MAC learning limit on the port. Available options include:
User Defined: Select this option to set the limit manually.
No Limited: Select this option to set no limit.
67
Item Description
Set broadcast suppression on the port. You can suppress broadcast traffic by
percentage or by PPS as follows:

Port mirroring configuration
Introduction to port mirroring
Port mirroring is the process of copying the packets passing through a port (called a mirroring port) to
another port (called the monitor port) connected with a monitoring device for packet analysis.
You can mirror inbound, outbound, or bidirectional traffic on a port as needed.
Implementing port mirroring
Port mirroring is implemented through local port mirroring groups. The following subsections describe how
local port mirroring is implemented.
Local port mirroring
In local port mirroring, all packets (including protocol and data packets) passing through a port can be
mirrored. Local port mirroring is implemented through a local mirroring group.
As shown in a, packets on the mirroring port are mirrored to the monitor port for the data monitoring device
to analyze.

Loopback test configuration
Overview
You can check whether an Ethernet port works normally by performing the Ethernet port loopback test,
during which the port cannot forward data packets normally.
Ethernet port loopback test can be an internal loopback test or an external loopback test.
In an internal loopback test, self loop is established in the switching chip to check whether there is a
chip failure related to the functions of the port.
In an external loopback test, a loopback plug is used on the port. Packets forwarded by the port will
be received by itself through the loopback plug. The external loopback test can be used to check
whether there is a hardware failure on the port.
Loopback operation

After selecting a testing type, you need to select a port on which you want to perform the loopback test from
the chassis front panel.
After that, click Test to start the loopback test, and you can see the test result in the Result box, as shown in
a.
a. Loopback test result
Configuration guidelines
Note the following when performing a loopback test:
You can perform an internal loopback test but not an external loopback test on a port that is physically
down, but you can perform neither test on a port that is manually shut down.
The system does not allow Rate, Duplex, Cable Type and Port Status configuration on a port under a
loopback test.
An Ethernet port works in full duplex mode when the loopback test is performed, and restores its
original duplex mode after the loopback test.

VCT
Overview
NOTE:
The fiber interface of a SFP port does not support this feature.
A link in the up state goes down and then up automatically if you perform this operation on one of the
Ethernet interfaces forming the link.
You can use the Virtual Cable Test (VCT) function to check the status of the cable connected to an Ethernet
port on the device. The check result is returned in less than 5 seconds. The test covers whether short circuit
or open circuit occurs on the cable and the length of the faulty cable.
Testing cable status
Select Device VCT from the navigation tree to enter the page for testing cable status. Select the port you
want to test in the chassis front panel and then click Test. The test result is returned in less than 5 seconds and
displayed in the Result text box, as shown in a.

Item Description
Status and length of the cable.
The status of a cable can be normal, abnormal, abnormal(open), abnormal(short), or
failure.
When a cable is normal, the cable length displayed is the total length of the cable.
Cable status
When a cable is not normal, the cable length displayed is the length of the cable
between the current port and the location where fault occurs.
IMPORTANT:
The error of the length detected is within 5 meters.
