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 8

• Web Access on page 8

• Understanding the User Interfaces on page 9

• Interface Naming Convention on page 14

Switch Management Interface

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.

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.

Web Management User Guide

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:

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 

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.

Web Management User Guide

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

Use the SNTP Global Configuration page to view and adjust date and time settings. To display the SNTP Global Configuration page, click System  Management > Time  SNTP

Global Configuration.

Web Management User Guide

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

LLDP

The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations on an 802 LAN to advertise major capabilities and physical descriptions. This information is viewed by a network manager to identify system topology and detect bad configurations on the LAN.

From the LLDP link, you can access the following pages:

• LLDP on page 72

• LLDP-MED on page 78

LLDP is a one-way protocol; there are no request/response sequences. Information is advertised by stations implementing the transmit function, and is received and processed by stations implementing the receive function. The transmit and receive functions can be enabled/disabled separately per port. By default, both transmit and receive are disabled on all ports. The application is responsible for starting each transmit and receive state machine appropriately, based on the configured status and operational state of the port.

The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an enhancement to LLDP with the following features:

• Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority, and DiffServ settings),

enabling plug and play networking.

• Device location discovery for creation of location databases.

• Extended and automated power management of Power over Ethernet endpoints.

• Inventory management, enabling network administrators to track their network devices

and determine their characteristics (manufacturer, software and hardware versions, serial/asset number).

• MVR Configuration on page 147

• Address Table on page 152

• Ports on page 158

• Link Aggregation Groups on page 161

VLANs

Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast, and like a router, it partitions the network into logical segments, which provides better administration, security and management of multicast traffic.

By default, all ports on the switch are in the same broadcast domain. VLANs electronically separate ports on the same switch into separate broadcast domains so that broadcast packets are not sent to all the ports on a single switch. When you use a VLAN, users can be grouped by logical function instead of physical location.

Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. An end station may omit the tag, or the VLAN portion of the tag, in which case the first switch port to receive the packet may either reject it or insert a tag using its default VLAN ID. A given port may handle traffic for more than one VLAN, but it can only support one default VLAN ID.

From the VLAN link, you can access the following pages:

• Basic on page 97

• Advanced on page 99

Internal VLAN Configuration

This section displays the allocation base and the allocation mode of internal VLAN. The internal VLAN is reserved by port-based routing interface and invisible to the end user. Once these internal VLANs are allocated by port-based routing interface, they are cannot be assigned to a routing VLAN interface.

1. Use Internal VLAN Allocation Base to specify the VLAN Allocation Base for the routing

interface. The default base of the internal VLAN is 1 to 4093.

2. Use the optional Internal VLAN Allocation Policy field to specify a policy for the internal

VLAN allocation. There are two policies supported: ascending and descending.

VLAN Configuration

1. Use VLAN ID to specify the VLAN Identifier for the new VLAN. The range of the VLAN

ID is 1 to 4093.
