1. Getting Started
This chapter provides an overview of starting your NETGEAR ProSafe® Managed Switches and
accessing the user interface. This chapter contains the following sections:
• Switch Management Interface on page 9
• Web Access on page 9
• Web Access on page 9
• Understanding the User Interfaces on page 10
• Interface Naming Convention on page 18
Switch Management Interface
The NETGEAR ProSafe® Managed Switches contain an embedded Web server and
management software for managing and monitoring switch functions. ProSafe® Managed
Switches function as simple switches without the management software. However, you can
use the management software to configure more advanced features that can improve switch
efficiency and overall network performance.
1
Web-based management lets you monitor, configure, and control your switch remotely using
a standard Web browser instead of using expensive and complicated SNMP software
products. From your Web browser, you can monitor the performance of your switch and
optimize its configuration for your network. You can configure all switch features, such as
VLANs, QoS, and ACLs by using the Web-based management interface.
Web Access
To access the ProSafe® Managed Switches management interface:
• Open a Web browser and enter the IP address of the switch in the address field.
You must be able to ping the IP address of the ProSafe® Managed Switches management
interface from your administrative system for Web access to be available. If you did not
change the IP address of the switch from the default value, enter 169.254.100.100 into the
address field.
Accessing the switch directly from your Web browser displays the login screen shown below.
Chapter 1. Getting Started | 9
ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual
Understanding the User Interfaces
ProSafe® Managed Switches software includes a set of comprehensive management
functions for configuring and monitoring the system by using one of the following methods:
• Web user interface
• Simple Network Management Protocol (SNMP)
• Command Line Interface (CLI)
Each of the standards-based management methods allows you to configure and monitor the
components of the ProSafe® Managed Switches software. The method you use to manage
the system depends on your network size and requirements, and on your preference.
The ProSafe® Managed Switch Web Management User Manual describes how to use the
Web-based interface to manage and monitor the system.
Using the Web Interface
To access the switch by using a Web browser, the browser must meet the following software
requirements:
• HTML version 4.0, or later
• HTTP version 1.1, or later
• Java Runtime Environment 1.6 or later
Use the following procedures to log on to the Web interface:
1. Open a Web browser and enter the IP address of the switch in the Web browser
address field.

Using SNMP
The ProSafe® Managed Switches software supports the configuration of SNMP groups and
users that can manage traps that the SNMP agent generates.
ProSafe® Managed Switches use both standard public MIBs for standard functionality and
private MIBs that support additional switch functionality. All private MIBs begin with a “-”
prefix. The main object for interface configuration is in -SWITCHING-MIB, which is a private
MIB. Some interface configurations also involve objects in the public MIB, IF-MIB.
SNMP is enabled by default. The System
Management System Information Web page,
which is the page that displays after a successful login, displays the information you need to
configure an SNMP manager to access the switch.
Any user can connect to the switch using the SNMPv3 protocol, but for authentication and
encryption, the switch supports only one user which is admin; therefore there is only one
profile that can be created or modified.
To configure authentication and encryption settings for the SNMPv3 admin profile by using
the Web interface:
1. Navigate to the System
SNMP SNMPv3 User Configuration page.
2. To enable authentication, select an Authentication Protocol option, which is either MD5 or
SHA.
3. To enable encryption, select the DES option in the Encryption Protocol field. Then, enter
an encryption code of eight or more alphanumeric characters in the Encryption Key field.
4. Click Apply.
To access configuration information for SNMPv1 or SNMPv2, click System
SNMP
SNMPv1/v2 and click the page that contains the information to configure.

Time
ProSafe® Managed Switches software supports the Simple Network Time Protocol (SNTP).
You can also set the system time manually
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. ProSafe® Managed Switches
software operates only as an SNTP client and cannot provide time services to other systems.
Time sources are established by Stratums. Stratums define the accuracy of the reference
clock. The higher the stratum (where zero is the highest), the more accurate the clock. The
device receives time from stratum 1 and above since it is itself a stratum 2 device.
The following is an example of stratums:
• Stratum 0: A real-time clock is used as the time source, for example, a GPS system.
• Stratum 1: A server that is directly linked to a Stratum 0 time source is used. Stratum 1
time servers provide primary network time standards.
• Stratum 2: The time source is distanced from the Stratum 1 server over a network path.
For example, a Stratum 2 server receives the time over a network link, via NTP, from a
Stratum 1 server.
Information received from SNTP servers is evaluated based on the time level and server
type.
SNTP time definitions are assessed and determined by the following time levels:
• T1: Time at which the original request was sent by the client.
• T2: Time at which the original request was received by the server.
• T3: Time at which the server sent a reply.
• T4: Time at which the client received the server's reply.
The device can poll Unicast server types for the server time.
Polling for Unicast information is used for polling a server for which the IP address is known.
SNTP servers that have been configured on the device are the only ones that are polled for
synchronization information. T1 through T4 are used to determine server time. This is the
preferred method for synchronizing device time because it is the most secure method. If this
method is selected, SNTP information is accepted only from SNTP servers defined on the
device using the SNTP Server Configuration page.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.

SNTP Global Configuration
SNTP stands for Simple Network Time Protocol. As its name suggests, it is a less
complicated version of Network Time Protocol, which is a system for synchronizing the
clocks of networked computer systems, primarily when data transfer is handled via the
Internet.
1. Use Client Mode to specify the mode of operation of SNTP Client. An SNTP client may
operate in one of the following modes.
• Disable - SNTP is not operational. No SNTP requests are sent from the client nor are
any received SNTP messages processed.
• Unicast - SNTP operates in a point to point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally the round-trip delay and local clock offset relative
to the server.
• Broadcast - SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address has a
single subnet scope while a multicast address has Internet wide scope.
Chapter 2. Configuring System Information | 39
ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual
Default value is Disable.
2. Use Port to specify the local UDP port to listen for responses/broadcasts. Allowed range is
1 to 65535. Default value is 123.
3. Use Unicast Poll Interval to specify the number of seconds between unicast poll requests
expressed as a power of two when configured in unicast mode. Allowed range is (6 to 10).
Default value is 6.
4. Use Broadcast Poll Interval to specify the number of seconds between broadcast poll
requests expressed as a power of two when configured in broadcast mode. Broadcasts
received prior to the expiry of this interval are discarded. Allowed range is (6 to 10). Default
value is 6.
5. Use Unicast Poll Timeout to specify the number of seconds to wait for an SNTP response
when configured in unicast mode. Allowed range is (1 to 30). Default value is 5.
6. Use Unicast Poll Retry to specify the number of times to retry a request to an SNTP server
after the first time-out before attempting to use the next configured server when configured in
unicast mode. Allowed range is (0 to 10). Default value is 1.
7. When using SNTP/NTP time servers to update the switch's clock, the time data received
from the server is based on Coordinated Universal Time (UTC) which is the same as
Greenwich Mean Time (GMT). This may not be the time zone in which the switch is located.
Use Time Zone Name to configure a timezone specifying the number of hours and
optionally the number of minutes difference from UTC with Offset Hours and Offset Minutes.
The time zone can affect the display of the current system time. The default value is UTC.
8. Use Offset Hours to specify the number of hours difference from UTC. See Time Zone
Name (
step 7 previous) for more information. Allowed range is (-24 to 24).The default value
is 0.
9. Use Offset Minutes to specify the number of Minutes difference from UTC. See Time Zone

3. Use Port Priority to determine which ports can deliver power when total power delivered by
the system crosses a certain threshold. The switch may not be able to supply a power to all
connected devices. Priority is used to determine which ports can supply power. The lower
numbered port which is one of the ports of the same priority will have a higher priority.
• low - Low priority.
• high - High priority.
• critical - Critical priority.
4. Use High Power Mode to specify one of the following:
• Disable value means that a port is powered in the IEEE 802.3af mode.
• Legacy value means that a port is powered using high-inrush current, used by legacy
PDs whose power requirement is more than 15W from powerup.
• Pre-802.3at value means that a port is powered in the IEEE 802.3af mode initially,
switched to the high-power IEEE 802.3at mode before 75msec. This mode needs to
be used, if PD is NOT performing Layer 2 Classification Or PSE is performing 2-Event
Layer 1 Classification.
• 802.3at value means that a port is powered in the IEEE 802.3at mode, i.e., if class
detected by PSE is not the class4, then the PSE port will not power up the PD.

either (Client Address or IP Mask) value is 0.0.0.0, access is allowed from any IP address.
Otherwise, every client's address is ANDed with the mask, as is the Client Address, and, if
the values are equal, access is allowed. For example, if the Client Address and Client IP
Mask parameters are 192.168.1.0/255.255.255.0, then any client whose address is
192.168.1.0 through 192.168.1.255 (inclusive) will be allowed access. To allow access from
only one station, use a Client IP Mask value of 255.255.255.255, and use that machine's IP
address for Client Address.
3. Client IP Mask - Taken together, the Client Address and Client IP Mask denote a range of
IP addresses from which SNMP clients may use that community to access this device. If
either (Client Address or IP Mask) value is 0.0.0.0, access is allowed from any IP address.
Otherwise, every client's address is ANDed with the mask, as is the Client Address, and, if
the values are equal, access is allowed. For example, if the Client Address and Client IP
Mask parameters are 192.168.1.0/255.255.255.0, then any client whose IP address is
192.168.1.0 through 192.168.1.255 (inclusive) will be allowed access. To allow access from
only one station, use a Client IP Mask value of 255.255.255.255, and use that machine's IP
address for Client Address.
4. Use Access Mode to specify the access level for this community by selecting Read/Write or
Read Only from the pull-down menu.
5. Use Status to specify the status of this community by selecting Enable or Disable from the
