Getting Started

NOTE:

 This manual applies to the HP V1905-48 Switch JD994A, HP V1905-24 Switch JD990A, and HP

V1905-24-PoE Switch JD992A, which are referred to as the Switch.

 This manual uses the Web interfaces of the HP V1905-24-PoE Switch JD992A in the example text.

This chapter contains introductory information about the installation of the Switch and how the Switch can be used in your network. It covers the following topics:

 Introducing the Switch  Installing the Switch  Configuring IP Address

Introducing the Switch

This chapter covers summary information about the hardware and the following topics:

 Overview of the Switch  Summary of Hardware Features  Front View Detail  LED Status Indicators  System Specifications

Overview of the Switch

 The HP V1905-24 Switch JD990A is a versatile, easy-to-use configurable switch.  The HP V1905-24-PoE Switch JD992A is a versatile, easy-to-use configurable Power-over-Ethernet

(PoE) Switch.

 The HP V1905-48 Switch JD994A is a versatile, easy-to-use configurable switch.

Each Switch is ideal for users who want the high-speed performance of 10/100 switching with the added functionality of Gigabit copper and fiber links, but do not need sophisticated management capabilities. The Switch is shipped ready for use. No configuration is necessary.

Summary of Hardware Features

Table 37 summarizes the hardware features supported by the Switch.

Forwarding Modes

Duplex Modes Half and full duplex on all front panel ports.

Auto MDI/MDIX

Flow Control In full duplex operation all ports are supported.

Traffic Prioritization Four traffic queues per port.

Gigabit Combo Ports

Mounting 19-inch rack or standalone mounting.

Store and Forward.

Supported on all ports. If fiber SFP transceivers are used, Auto MDIX is not supported.

10/100 Mbps ports.

Each port automatically determines the speed and duplex mode of the connected equipment and provides a suitable switched connection. The 10/100 Mbps ports can operate in either half-duplex or full-duplex mode.

The 2 Gigabit combo ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and a 1000 Mbps core network.

When an SFP port is in operation, the corresponding 1000BASE-T port is disabled. The 1000 Mbps connections can only operate in full duplex mode.

Fanless design (supported by HP V1905-24 Switch JD990A and HP V1905-48 Switch JD994A)

PoE (Only supported by HP V1905-24-PoE Switch JD992A)

Front View Detail

Figure 46 shows the front panel of the HP V1905-24 Switch JD990A 26-Port unit.

Figure 46 HP V1905-24 Switch JD990A 26-Port—front panel.

Figure 47 shows the front panel of the HP V1905-24-PoE Switch JD992A 26-Port unit.

Silent operation whether used in a rack or desktop situation.

Each RJ-45 port supports the IEEE 802.3af PoE standard. Any

802.3af compliant device attached to a port can directly draw power from the switch over the Ethernet cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability.

Installing the Switch

This section contains information that you need to install and set up the switch. It covers the following topics:

 Before You Begin  Positioning the Switch  Rack-Mounting or Free-Standing  Supplying Power to the Switch  Checking for Correct Operation  Using SFP Transceivers  Performing Spot Checks

Before You Begin

Before installing or removing any components from the switch or carrying out any maintenance procedures, read the Safety and Compliance Guide chapter in this guide.

Positioning the Switch

The switch is suitable for use in an office environment where it can be free-standing or mounted in a standard 19-inch equipment rack.

Alternatively, the switch can be rack-mounted in a wiring closet or equipment room. A mounting kit, containing two mounting brackets and four screws, is supplied with the switch.

When deciding where to position the switch, ensure that:

 It is accessible and cables can be connected easily.  Cabling is away from sources of electrical noise. These include lift shafts, microwave ovens, and air

conditioning units. Electromagnetic fields can interfere with the signals on copper cabling and introduce errors, thereby slowing down your network.

 Water or moisture cannot enter the case of the unit.  Air flow around the unit and through the vents on the side of the case is not restricted (HP recommends

that you provide a minimum of 25 mm (1 in.) clearance).

 The air is as free from dust as possible.  Temperature operating limits are not likely to be exceeded. HP recommends that the unit is installed in

a clean, air conditioned environment.

NOTE:

It is always good practice to wear an anti-static wrist strap connected to a ground point when installing network equipment. If one is not available, try to keep in contact with a the unit's ports and connectors, if possible. Static discharge can cause reliability problems in your equipment.

rounded rack and avoid touchin

Rack-Mounting or Free-Standing

The unit can be mounted in a 19-inch equipment rack using the mounting kit or it can be free standing. Do not place objects on top of the unit or stack.

CAUTION:

If installing the switch in a free-standing stack of different size Baseline or Super stack 3 units, the smaller units must be installed above the larger ones. Do not have a free-standing stack of more than six units.

Using the Mounting Kit

The switch is supplied with two mounting brackets and four screws. These are used for rack mounting the unit. When mounting the unit, refer to the guidelines given in Positioning the Switch.

The switch is 1U (1.7 inches) high and will fit in a standard 19-inch rack.

CAUTION:

Disconnect all cables from the unit before continuing. Remove the self-adhesive pads from the underside of unit, if already fitted.

To rack-mount the switch:

1. Place the unit the right way up on a hard, flat surface with the front facing towards you.

2. Locate a mounting bracket over the mounting holes on one side of the unit.

3. Insert the two screws supplied in the mounting kit and fully tighten with a suitable screwdriver, as

shown in Figure 49.

Figure 49 Rack Mounting the Unit

4. Insert the unit into the 19-inch rack and secure with suitable screws (not provided), as shown in Figure

Figure 50 Mount the HP V1905 Switch to a rack

5. Reconnect the cables.

Placing Units On Top of Each Other

If the switch units are free-standing, up to six units can be placed one on top of the other. If you are mixing a variety of Baseline and Super Stack units, the smaller units must be positioned at the top.

If you are placing switch units one on top of the other, you must use the self-adhesive rubber pads supplied. Apply the pads to the underside of each switch, sticking one in the marked area at each corner.

Place the switch units on top of each other, ensuring that the pads of the upper unit line up with the recesses of the lower unit.

Supplying Power to the Switch

Power problems can be the cause of serious failures and downtime in your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network outages. HP recommends that you install power conditioning, especially in areas prone to blackout, power dips and electrical storms.

The unit is intended to be grounded. Ensure it is connected to earth ground during normal use. Installing proper grounding helps to avoid damage from lightning and power surges.

CAUTION:

Before powering on the switch, verify that the network cables and the power cable are securely connected.

To power on the switch:

1. Plug the power cord into the power socket on the rear panel of the switch.

2. Plug the other end of the power cord into a power outlet.

Checking for Correct Operation

After you power on the switch, it automatically performs a power-on self-test (POST). During POST, the Power LED on the front panel of the switch flashes green.

When POST is complete, the Power LED turns green. If the Power LED turns yellow after POST, it means that POST failed and the switch has entered its fail-safe mode.

The following summarizes the possible colors for the Power LED after POST.

Table 40 Summarizes the possible colors for the Power LED after POST

Status Meaning

Green The unit is powered on and ready for use.

Yellow

Off

Power-on self-test or loop back test failed. The switch is in fail-safe mode. This can happen if a port or ports fail when the switch was powered on.

The unit is not receiving power.

 Verify that the power cord is connected correctly, and then try powering on the

switch again

 If the switch still does not operate, contact your HP network supplier

If POST fails, try the following:

 Power off the switch, and then power it on again. Check the Power LED and see if POST was

successfully completed.

 Reset the switch. See “Resetting to Factory Defaults.”

CAUTION:

Resetting the switch to its factory default erases all your settings. You will need to reconfigure the switch after you reset it.

If these do not resolve the issue, please contact your HP network supplier for assistance.

Using SFP Transceivers

The following sections describe how to insert an SFP transceiver into an SFP slot.

NOTE:

SFP transceivers are hot-insertable and hot-swappable. You can remove them from and insert them into any SFP port without having to power down the switch.

Inserting an SFP Transceiver

To be recognized as valid, the SFP transceiver must have the following characteristics:

1000BASE-SX or 1000BASE-LX media type:

 1000BASE-SX SFP transceiver

Use this transceiver to connect the switch directly to a multimode fiber-optic cable.

 1000BASE-LX SFP transceiver

Use this transceiver to connect the switch directly to a single mode fiber-optic cable or to multi-mode fiber using a conditioned launch cable.

To activate the SFP port:

1. Hold the transceiver so that the fiber connector is toward you and the product label is visible, as shown

in Figure 51.Ensure the wire release lever is closed (in the upright position).

Figure 51 Inserting an SFP Transceiver

2. Gently slide the transceiver into the SFP slot until it clicks into place.

CAUTION:

SFP transceivers are keyed and can be properly inserted only one way. If the transceiver does not click

hen you insert it, remove it, turn it over, and reinsert it.

3. Remove the plastic protective cover, if fitted.

4. Connect the fiber cable.

5. Attach a male duplex LC connector on the network cable into the duplex LC connector on the

transceiver.

6. Connect the other end of the cable to a device fitted with an appropriate Gigabit Ethernet connection.

7. Check the Module Active LEDs on the front of the switch to ensure that the SFP transceiver is operating

correctly.

Removing an SFP Transceiver

To remove an SFP transceiver:

1. Disconnect the cable from the transceiver.

2. Move the wire release lever downwards until it is pointing toward you.

3. Pull the wire release lever toward you to release the catch mechanism.

The SFP transceiver should slide out easily.

Performing Spot Checks

At frequent intervals, you should visually check the switch. Regular checks can give you an early warning of a possible failure; any problems can then be attended to when there will be least effect on users.

HP recommends periodically checking the items listed in Table 41.

Table 41 Items to Check

Item O

Cooling fan

Cabling

eration

Where possible, check that the cooling fan is operating by listening to the unit. The fan is fitted near to the front right hand side of the unit (when viewed from the front).

Check that all external cabling connections are secure and that no cables are pulled taut.

Configuring IP Address

The switch’s IP configuration is determined automatically using DHCP, or manually using values you assign.

By default, the switch will use its default IP information. The default IP address is 169.254.xxx.xxx. If the MAC address is 08004E000102, the IP address would be 169.254.1.2.

Automatic IP Configuration using DHCP

When you use the automatic IP configuration method, the switch tries to obtain its IP information without requesting user intervention from a DHCP server on the network.

You should use the automatic IP configuration method if:

 Your network uses DHCP to allocate IP information, or  Flexibility is needed. If the switch is deployed onto a different subnet, it will automatically reconfigure

itself with an appropriate IP address, instead of you having to manually reconfigure the switch.

You can use ip address dhcp-alloc command to define automatic IP configuration method and use display ip command to view the automatically allocated IP Information through the Console Port (see “CLI Reference

Guide”).

Manual IP Configuration

When you configure the IP information manually, the switch remembers the information that you enter until you change it again.

You should use the manual IP configuration method if:

 You do not have a DHCP server on your network, or  You want to remove the risk of the IP address ever changing, or  Your DHCP server does not allow you to allocate static IP addresses.

NOTE:

For most installations, HP recommends that you configure the switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.

You can use ip address command to configure the static IP for your switch through the Console Port (see “CLI

Reference Guide”).

Connecting To the Web Interface

The switch has a built-in Web interface that you can use to set the user password, change the IP address that is assigned to the switch, and configure its advanced settings.

This chapter introduces the setting the menu items and buttons that are available on the Web interface. The following topics are covered:

 Requirements for Accessing the Web Interface  Choosing a Web Browser  Default User and Password  Logging On to the Web Interface  Navigating the Web Interface

Configuring System Access

Network administrators can define user name, password, and access level for users using the System Access Interface. The Multi-Session Web feature is enabled on switch and allows 10 users to be created and access the switch concurrently. Access levels provide read or read/write permissions to users for configuring the switch. Login information is managed in the local database. A unique password is required for each user. Two access levels exist on the Web Interface:

 Management access level: Provides the user with read/write access rights. There is always one

management level user configured for the switch.

 Monitor access level: Provides the user with read-only system access rights.

Configuring MAC Address Table

MAC addresses are stored in either the static address or the dynamic address databases. A packet addressed to a destination stored in one of the databases is forwarded immediately to the port.

The Dynamic Address Table can be sorted by interface, VLAN, and MAC address. MAC addresses are dynamically learned as packets from sources arrive at the switch. MAC addresses are associated with ports by learning the ports from the frames source address. Frames addressed to a destination MAC address that is not associated with any port are flooded to all ports of the relevant VLAN.

Static addresses are manually configured. In order to prevent the bridging table from overflowing, dynamic MAC addresses, from which no traffic is seen for a certain period, are erased.

CAUTION:

 Before manually setting a port to full-duplex mode, verify that the device connected to the port is also

manually set to the same speed and duplex setting. If connecting link partners are left to autonegotiate for a link manually set on this switch to full-duplex, they will always negotiate to half-duplex, resultin

in a duplex mismatch. This can result in a significant reduction in network performance. If you

Configuring VLAN

VLANs are logical subgroups with a Local Area Network (LAN) which combine user stations and network devices into a single unit, regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to reduce the amount of time it takes for network changes, additions, and moves to be implemented. VLANs restrict traffic within the VLAN.

VLANs have no minimum number of ports, and can be created per unit, per device, or through any other logical connection combination, since they are software-based and not defined by physical attributes.

VLANs function at Layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router working at a protocol level is required to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with VLANs. Broadcast and Multicast traffic is transmitted only in the VLAN in which the traffic is generated.

VLAN tagging provides a method of transferring VLAN information between VLAN groups. VLAN1 is the default VLAN and always contains untagged ports. All ports are members of VLAN1 by default. If the untagged port is moved to a new VLAN, the port is removed from VLAN1. For example: If an untagged port 24 is moved to VLAN 5, the port will no longer be a member of VLAN1. However, if the port is added to VLAN5 as a tagged port it then remains untagged in VLAN1.

Aggregating Port

Overview

Link aggregation aggregates multiple physical Ethernet ports into one logical link, called a Link Aggregation Group (LAG).

It allows you to increase bandwidth by distributing traffic across the member ports in the aggregation group. In addition, it provides reliable connectivity because these member ports can dynamically back up each other.

LACP

Link Aggregation Control Protocol (LACP) based on the IEEE802.3ad standard can be used for dynamic link aggregation. An LACP-enabled port sends link aggregation control protocol data units (LACPDUs) to tell the peer about its system priority, system MAC address, port priority, port number and operation key. After receiving the information from the sender, the receiver compares it with the locally saved information about other ports, chooses member ports for the aggregation group and reaches agreement about whether a port can join or leave a dynamic aggregation group.

NOTE:

link aggregation, LACP generates a configuration mix according to the port configuration (rate,

Durin duplex, basic configuration, management key), which is called an operation key.

Link Aggregation Types

The switch supports two link aggregation types:

 Manual Aggregation  Static LACP Aggregation

1. Manual Aggregation

Manual aggregation is configured manually, and cannot be added or removed automatically. A manual or static LACP aggregation group must contain at least one member port. Member ports in a manual aggregation are LACP-disabled.

A port in a manual aggregation group can be in one of the two states: selected or unselected. In a manual aggregation group, only the selected ports can forward user service packets.

In a manual aggregation group, the system sets the ports to selected or unselected state according to the following rules.

 Among the ports in an aggregation group that are in an up state, the system determines the port with

one of the following settings being the highest as the master port (in descending order): full duplex/high speed, full duplex/low speed, half duplex/high speed, half duplex/low speed. The ports with their rate, duplex mode and link type being the same as that of the master port are selected ports, and the rest are unselected ports.

 There is a limit on the number of selected ports in an aggregation group. If the number of the selected

ports in an aggregation group exceeds the maximum number supported by the switch, those with lower port numbers operate as the selected ports, and others as unselected ports.

Among the selected ports in an aggregation group, the one with smallest port number operates as the master port. Other selected ports are the member ports.

2. Static LACP Aggregation

A static LACP aggregation group is also manually created. All its member ports are manually added and can be manually removed (this prevents the system from automatically adding or removing ports from the group). LACP is enabled on each of the member ports in the static aggregation group. When you remove a static aggregation group, all the member ports in the up state form one or multiple dynamic aggregations with LACP enabled.

A port in a static aggregation group can be in one of the two states: selected or unselected.

 Both the selected and the unselected ports in the up state can receive and send LACP protocol packets.  Only the selected ports can receive and send service packets; the unselected ports cannot.

In a static aggregation group, the system sets the ports to selected or unselected state according to the following rules.

 Among the ports in an aggregation group that are in an up state, the system determines the port with

the following settings being the highest as the master port (in descending order): full duplex/high speed, full duplex/low speed, half duplex/high speed, half duplex/low speed. The ports with their rate, duplex mode and link type being the same as that of the master port are selected ports, and the rest are unselected ports.

 The ports connected to a peer device different from the one the master port is connected to, or those

connected to the same peer device as the master port but to a peer port that is not in the same aggregation group as the peer port of the master port, are unselected ports.

 The system sets the ports with basic port configuration different from that of the master port to

unselected state.

 There is a limit on the number of selected ports in an aggregation group. Therefore, if the number of

the selected ports in an aggregation group exceeds the maximum number supported by the switch, those with lower port numbers operate as the selected ports, and others as unselected ports.

Configuring STP

STP (Spanning Tree Protocol) is a bridge-based system for providing fault tolerance on networks and can be used to detect and disable network loops. The spanning tree ensures that the optimal path is maintained between spanning tree-compliant networked devices by:

 Disabling redundant paths when the main paths are operational.  Enabling redundant paths if the main paths fail.

Spanning tree uses a distributed algorithm to select a bridging device that serves as the root of the spanning tree network.

The bridging device, known as the Root Bridge, generates bridge protocol data units (BPDUs) on all ports at a regular interval known as the Hello Time. All other spanning tree-compliant devices on the network have a designated Root Port. This is the Port nearest the Root Bridge and it is used for receiving the BPDUs initiated by the Root Bridge. If a bridge does not get a Hello BPDU after a predetermined interval, the bridge assumes that the link to the Root Bridge is down. This bridge will then initiate negotiations with other bridges to reconfigure the network to reestablish a valid network topology.

tion

After all the bridges on the network have determined the configuration of their ports, each bridge only forwards traffic between the Root Port and the ports that are the Designated Bridge Ports for each network segment. All other ports are blocked, which means that they are prevented from forwarding traffic.

The device supports the following STP versions:

 Classic STP: Provides a single path between end stations, avoiding and eliminating loops.  Rapid STP: Detects and uses network topologies that provide faster convergence of the spanning tree,

without creating forwarding loops. While Classic STP prevents Layer 2 forwarding loops in a general network topology, convergence can take between 30-60 seconds.

Configuring IGMP Snooping

This section contains information for configuring IGMP Snooping.

When IGMP Snooping is enabled, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines:

 Which ports want to join which Multicast groups.  Which ports have Multicast routers generating IGMP queries.  Which routing protocols are forwarding packets and Multicast traffic.

Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast group is accepting members. This results in the creation of the Multicast filtering database.

This section contains the following topic:

Configuring Voice VLAN

Voice VLAN allows network administrators to enhance VoIP service by configuring ports to carry IP voice traffic from IP phones on a specific VLAN. VoIP traffic has a preconfigured Organizationally Unique Identifier (OUI) prefix in the source MAC address. Network Administrators can configure VLANs on which voice IP traffic is forwarded. Non-VoIP traffic is dropped from the Voice VLAN in auto Voice VLAN secure mode. Voice VLAN also provides QoS to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly. The system supports one Voice VLAN.

NOTE:

The HP V1905-48 Switch JD994A does not support improving the priority of voice streams.

There are two operational modes for IP Phones:

 IP phones are configured with VLAN-mode as enabled, ensuring that tagged packets are used for all

communications.

 If the IP phone’s VLAN-mode is disabled, the phone uses untagged packets. The phone uses untagged

packets while retrieving the initial IP address through DHCP. The phone eventually uses the Voice VLAN and starts sending tagged packets.

This section contains the following topics:

 Modifying OUI Definitions  Defining Voice VLAN Global Settings  Defining Voice VLAN Port Settings  Viewing Voice VLAN Port Settings  Viewing OUI Summaries  Viewing Voice VLAN

Modifying OUI Definitions

The Voice VLAN OUI Modify Page allows network administrators to add new OUIs or to remove previously defined OUIs from the Voice VLAN. The packet priority is derived from the source/destination MAC prefix. The packet gets a higher priority when there is a match with the OUI list. Using the OUI, network managers can add a specific manufacturer’s MAC addresses to the OUI table. Once the OUIs are added, all traffic received on the Voice VLAN ports from the specific IP phone with a listed OUI is forwarded on the voice VLAN.

Click Device  QoS  VoIP Traffic Setting  OUI Modify. The Voice VLAN OUI Modify Page opens.

Configuring SNMP

Simple Network Management Protocol (SNMP) provides a method for managing network devices. The switch supports the following SNMP versions:

 SNMP version 1  SNMP version 2c

The SNMP agents maintain a list of variables, which are used to manage the switch. The variables are defined in the Management Information Base (MIB). The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agents are controlled by access strings.

This section contains the following topics:

 Defining SNMP Communities  Removing SNMP Communities  Defining SNMP Traps  Removing SNMP Traps

Configuring LLDP

LLDP Overview

The Link Layer Discovery Protocol (LLDP) operates on the data link layer. With LLDP, a device can store and maintain information about itself and the directly-connected neighbor devices for network administrators to check link status.

LLDP Operating Mode

LLDP can operate in one of the following modes:

 TxRx: A port in this mode sends and receives LLDPDUs.  Tx: A port in this mode only sends LLDPDUs.  Rx: A port in this mode only receives LLDPDUs.  Disable: A port in this mode does not send or receive LLDPDUs.

TLV Types

TLVs encapsulated in LLDPDUs fall into these categories: basic TLVs, organizationally specific TLVs, and media endpoint discovery (MED) related TLVs.

Basic TLVs are the base of network device management. Organizationally specific TLVs are defined by the standard organization, while MED related TLVs are vendor specific for enhanced device management and are optional to LLDPDUs.

Configuring Global LLDP Parameters

Click Device  LLDP  Global Setup. The Global LLDP Parameters Page opens.

 Enabled: Enables LLDP globally.  Disabled: Disables LLDP globally.

By default, LLDP is disabled globally.

Set the interval for sending LLDPDUs.

A port operating in TxRx mode or Tx mode sends LLDPDUs to its directly connected device periodically.

By default, the interval is 30 seconds.

Set the TTL multiplier.

You can configure the TTL of locally sent LLDPDUs to determine how long they can be saved on a neighbor device by setting the TTL hold multiplier. The TTL is expressed as:

TTL multiplier × LLDPDU sending interval

By default, the TTL multiplier is 4.

Set the number of successive fast-sent LLDPDUs.

This fast sending mechanism allows your LLDPDU switch to be discovered by its neighbors quickly. After the specified numbers of LLDPDUs are sent, the normal sending interval restores.

The default fast count is 3.

Managing Switch Security

The Management Security section provides information for defining RADIUS authentication and port-based authentication.

This section includes the following topics:

 Defining Port-Based Authentication (802.1X)  Defining Radius Client  Configuring LDB  Configuring Broadcast Storm Control

Defining Port-Based Authentication (802.1X)

Port-based authentication authenticates users on a per-port basis via an external server. Only authenticated and approved system users can transmit and receive data. Ports are authenticated via the RADIUS server using the Extensible Authentication Protocol (EAP). Port-based authentication includes:

 Authenticators: Specifies the switch port which is authenticated before permitting system access.  Supplicants: Specifies the host connected to the authenticated port requesting to access the system

services.

 Authentication Server: Specifies the server that performs the authentication on behalf of the

authenticator, and indicates whether the supplicant is authorized to access system services.

Port-based authentication creates two access states:

 Controlled Access: Permits communication between the supplicant and the system, if the supplicant is

authorized.

 Uncontrolled Access: Permits uncontrolled communication regardless of the port state.

This section includes the following topics:

 Defining 802.1X Authentication  Viewing 802.1X Authentication

Defining Radius Client

Remote Authentication Dial-in User Service (Radius) is a logon authentication protocol that uses software running on a central server to control access to Radius-aware devices on the network. An authentication server contains a database of multiple user name/password pairs with associated privilege levels for each user or group that require management access to a switch.

The Radius Client Setup Page allows the administrator to configure the parameters for the switch acting as the RADIUS client.

Click Security  RADIUS Client  Setup. The Radius Client Setup Page opens.

tion

Configuring LDB

If your switch is not enabled with an advanced authentication method, like RADIUS, for authentication, you can use the local database (LDB) feature to perform local authentication (port-based authentication). After the switch is enabled with the LDB feature and related access rights are configured, a user trying to access an address through the switch will be authenticated. After successful authentication, the switch allows the user to use the corresponding port. Otherwise, the port is blocked.

Configuring Broadcast Storm Control

Broadcast Storm Control limits the amount of Multicast and Broadcast frames accepted and forwarded by the switch. When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes on all ports.

A Broadcast Storm is a result of an excessive amount of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out.

Broadcast Storm is enabled for all Gigabit ports by defining the packet type and the rate the packets are transmitted. The system measures the incoming Broadcast and Multicast frame rates separately on each port, and discards the frames when the rate exceeds a user-defined rate.

Packet threshold is ignored if Broadcast Storm Control is disabled.
