8- and 24-Port Gigabit L2 Managed Power-over-Ethernet (PoE) Switches

2. Overview

2.1 Introduction

The 8-Port and 24-Port Gigabit L2 Managed Power-over- Ethernet Switches (LPB4008Aand LPB4024A) are standard switches that meet all IEEE

802.3/u/x/z Gigabit Ethernet specifications. The LPB4008A switch includes six 10-/100-/1000-Mbps TP ports and two Gigabit TP/SFP ports. The LBP4024A switch includes twenty 10-/100-/1000-Mbps TP ports and four Gigabit TP/SFP ports. You can manage the switches through the RS-232 serial port via a direct connection, or through the Ethernet port using a CLI or Web-based management unit that’s associated with an SNMP agent. Using the SNMP agent, the network administrator can log on to the switch to monitor, configure, and control each port’s activity. Via its intelligent softwar e, the switch also featur es ACL, IP-MAC Binding, DHCP Snooping, QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Security, SNMP/RMON, and IGMP Snooping. Use it for both metro-LAN and office applications.

These PSE switches also comply with the IEEE 802.3af standard. An advanced auto-sensing algorithm enables power devices (PD) discovery, classification, current limit, and other necessary functions. It also protects against short circuits and auto-detects power-out to the PD.

This switch’s Port 7 and Port 8 (LPB4008A) or Ports 21–24 (LPB4024A) include two types of media—TP and SFP Fiber (LC, BiDi LC…). These ports support 10-/100-/1000-Mbps TP or 1000-Mbps SFP Fiber with auto-detect function. Use a 1000-Mbps SFP Fiber transceiver to expand a high-s peed connection.

• 1000-Mbps LC, Multimode, 50 m, SFP Fiber transceiver (LGB200C-MLC)

• 1000-Mbps LC, Single-Mode, 10 km, SFP Fiber transceiver (LGB200C- SLC10)

• 1000-Mbps LC, Single-Mode, 30 km, SFP Fiber transceiver (LGB200C- SLC30)

• 1000-Mbps Bi Di LC, Single-Mode, 20 km, 1550 nm SFP Fiber WDM transceiver (LGB204C)

• 1000-Mbps Bi Di LC, Single-Mode, 20 km, 1310 nm SFP Fiber WDM transceiver (LGB205C)

The 10-/100-/1000- Mbps TP standard Ethernet ports meet all IEEE 802.3/u/x/z Gi gabit and Fast Ethernet specifications. The 1000Mbps SFP Fiber transceiver has a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000BASE-SX/LX standards.

The 1000-Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic Wavelength Division Multiplexing (WDM) technology that transports a bi-directional full-duplex signal over a single fiber simultaneously.

"Active PHY Power Management" and "Perfect Reach Power Management " help reduce power consumption.

The switch also supports the IEEE Standard 802.1ab Link Layer Discovery Protocol to provide a debugging tool and enhance the networking management availability. It can auto-discover a device and its topology.

2.2 Features

 QoS: Supports Quality of Service using the IEEE 802.1P standard. There are two priority queue and packet transmission schedules.

 Spanning Tree: Supports IEEE 802.1D, IEEE 802.1w ( RSTP: Rapid Spanning Tree Prot ocol) standards.

 VLAN: Supports Port-based VLAN and IEEE802.1Q Tag VLAN;

Also supports 256 active VLANs and VLAN ID 1–4094.

 Port Trunking: Supports static port trunking and port trunking with IEEE 802.3ad LACP.

 Bandwidth Control: Supports ingress and egress per port bandwidth control.

 Port Security: Allows or denies forwarding and port security according to MAC address.

 SNMP/RMON

- SNMP agent and RMON MIB. The switch’s SNMP agent is client software that operates using SNMP protocol to receive commands from the SNMP manager (server site) and echo the corr esponding data (the MIB object). The SNMP agent actively issues TRAP information when it occurs.

- Remote Network Monitoring (RMON) is a branc h of the SNMP MIB

- The switch supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), and Ethernet MIB (RFC 1643).

 IGMP Snooping: Supports IGMP version 2 (RFC 2236): Use IGMP snooping to establish multicast groups that will forward multicast packets to member ports, and won’t waste bandwidth while IP multicast packets are running ov er the network.

 IGMP Proxy: multicast processing. The switch supports IGMP version 1 and IGMP version 2, to efficiently use network bandwidth, and provide fast response time for channel changing. IGMP version 1 (IGMPv1) is described in RFC1112, and IGMP version 2 (IGMPv2) is described in RFC 2236. Hosts interact with the system through the exchang e of IGMP messages. Similarly, when you configure IGMP proxy, the system exhanges IGMP messages with the router upstream. However, when acting as the proxy, the system performs the host portion of the IGMP ta sk on the upstream interface as follows:

- When queried, it sends group membership reports to the group.

724-746-5500 | blackbox.com

Chapter 2: Overview

- When one of its hosts joins a multicast address group to which none of its other hosts belong, it sends unsolicited group membership reports to that group.

- When the last host in a particular multicast group leaves the group, it sends an unsolicited leave group membership report to the all-routers group (244.0.0.2).

 PoE: 8 PoE ports allow power to be supplied to end devices , such as Wireles s Access Points or VoIP Phones, directly through the existing LAN cables, eliminating costs for additional AC wiring and reducing installation costs.

 Power Saving

- "Active PHY Power Management" detects when the client is idle. "Perfect Reach Power Management" detects the cable length automatically, then provides the different (lower) power level needed. This saves switch power and reduces power consumption.

 LLDP (IEEE 802.1AB Link Layer Discovery Protocol)

- The switch supports LLDP automated device discovery protocol for easy mapping of network management applications.

2.6 Optional SFP Fiber Transceiver Modules

Ports 7 and 8 on th e LPB4008A include two types of media: twisted-pair (TP) and optional small form factor pluggable (SFP) fiber (LC, BiDi LC, etc.) modules. The twisted-pair ports are the switch’s two rightmost RJ-45 twisted-pair connectors. For the fiber option, 1000-Mbps fiber transceiver modules slide into the switch’s two fiber module slots (located to the right of the twisted-pair conn ectors on th e switch’s front panel). The fiber transceiver modules are used for high-speed connection expansion. The two fib er ports can automatically detect 10/100/1000-Mbps TP or 1000-Mbps SFP fiber.

Five 1000-Mbps transceiver modules are available. Thes e modules are d escribed below and shown in Figures 2-7 and 2-8.

Figure 3-1. Installing the optional SFP fiber tran sceiver module.

Connecting the SFP Module to the Chassis

The optional SFP modules are hot-swappable, so you can plug or unplug them before or after powering on th e switch.

1. Verify that the SFP module is the right model and conforms to the chassis.

2. Slide the module into the slot. Make sure that the module is properly seated against the slot socket/connector.

3. Connect the fiber optic network cable to the connector(s) on the module.

If you want to install a s econd module in the LPB4008A switch or second, third, and fourth module in the LPB4024A switch, repeat steps 1–3.

3.1.2

TP Port and Cable Installation

1. The switch’s TP port supports MDI/MDI-X auto-crossover, so you can use both types of cable, straight-through (Cable pin-outs for

RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and cross-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2).

2. Use CAT5 RJ-45 TP cable to connect to one of the switch’s TP port and a network-aware device such as a workstation or a server.

3. Repeat the above steps, as needed, for e ach RJ-45 port you want to connect to a Gigabit 10/100/1000 T P device.

4. The switch is now ready to operate.

724-746-5500 | blackbox.com

Chapter 3: Installation

3.1.3 Power On

The switch supports a 100-240-VAC, 50-60-Hz power supply. The power supply will automatically convert the local AC power source to DC power. You can connect a device or module to the switch when it’s powered on or off. When the power is on, all port LED indicators will light up immediately and then go off. (The power LED remains on.) To reset the switch, simply power it off, then on again.

3.1.4 Firmware Loading

After resetting, the bootloader will load the firmware into the memory. (It will take about 30 seconds.) Then all LEDs on the switch will flash once and automatically perform a self-test. The switch is now in the ready state.

3.2 Installing the Switch in a 19-Inch Wiring Rack or Cabinet

CAUTION: Allow enough space for the cooling fan at both sides of the switch to provide ventilation. Wear a grounding device for electrostatic discharge.

1. Using two screws (included), attach the rackmount ears to the switch’s left and right sides. See Figure 3-2.

2. Line up the mounting holes on the switch as sembly (the switch with rackmount ears installed ) with the mounting holes on a 19"

wiring closet rack. Install two screws (included) to hold the switch in place in the rack.

3.3 Cabling Requirements

For successful installation and optimum network performance, use CAT5 or CAT5e cable.

3.3.1 Twisted-Pair Ports

For a Fast Ethernet TP network conn ection, use CAT5 or CAT5e cable that’s up to 100 meters long.

For a Gigabit Ethernet TP network connection, use CA T5 or CAT5e cable that’s up to 100 meters long. We recommend using CAT5e cable for Gigabit connections.

3.3.2 Fiber Transceiver Ports

There are two categories of fiber: multimode (MM) and single-mode (SM). Multimode fiber is categorized into several classes by the distance it supports. Th e classes are SX, LX, LHX, XD, and ZX . The fiber modules that work with the switch have LC and BIDI LC connectors.

724-746-5500 | blackbox.com

Chapter 3: Installation

• 62.5/125-μm multimode Gigabit fiber with multimode LC SFP module (LGB200C-MLC).

• 9/125-μm single-mode Gigabit fiber with single-mode LC SFP module (LGB200C-SLC10 orLGB200C-SLC30).

• 9/125-μm single-strand single-mode Gigabit fiber with BiDi LC1310-nm SFP module (LGB204C).

3.3.3 Switch Cascading in Topology

Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may uplink an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, which limit the timing requirement from physical signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and timing from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP.

The fiber, TP cables, and devices’ bit-time (round-trip) delay are described in Table 3-1.

Table 3-1. Cable’s bit-time (round-trip) delay.

1000BASE-X TP, Fiber 100BASE-TX TP 100BASE -F X Fiber

Round trip Delay: 4096 Round trip Delay: 512

Cat. 5 TP Wire: 11.12/m Cat. 5 T P Wire: 1.12/m Fiber Cable: 1.0/m

Fiber Cable: 10.10/m TP to fiber Converter: 56

Bit Time unit: 1ns (1sec./1000 Mega bit)

The sum of all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a halfduplex network segment (collision domain). For full-duplex operation, this will not apply. You may use the T P-Fiber module to extend the TP node distance over fiber optic cable and provide the long haul connection.

Bit Time unit: 0.01 s (1sec./100 Mega bit)

3.3.4 Typical Network Topology in Deployment

A hierarchical network with minimum levels of switches may reduce the timing delay between server and client station. This approach will minimize the number of switches in any one path, will lower the possibility of network loop, and will improve network efficiency. If more than two switches are connected in the same network, select one switch as a Level 1 switch and connect all other switches to it at Level 2. We recommend connecting the Server/Host to the Level 1 switch, if no VLAN or other special requirements are applied.

8- and 24-Port Gigabit L2 Managed Power-over-Ethernet (PoE) Switches

Case1: All switch ports are in the same local area network. Every port can access each other (See Figure 3-3).

Figure 3-3. No VLAN Configuration Diagram.

If VLAN is enabled and configured, each nod e in the network that can communicate with each other directly is bounded in the same VLAN area. Here VLAN area is defined by what VLAN you are using. The switch supports both port-bas ed VLAN and tag-based VLAN. The following diagram shows how port-based VLANs and tag-based VLANs work.

Case2a: Port-based VLAN (See Figure 3-4).

3.4 Configuring the Management Agent

3.4.1 Connect To Console Port

To configure the switch via the RS-232 console port, connect the switch’s serial port directly to a DTE device, for example, a PC, through an RS-232 cable with a DB9 connector. Next, run a terminal emulator with the default setting of the switch’s serial port. The RS-232 interface in the switch only supports 115200 bps baud rate with 8 data bits, 1 stop bit, no parity check, and no flow control.

RS-232 cable with female DB9 connector at both ends Default IP Setting: IP address = 192.168.1.1 Subnet mask = 255.255.255.0 Default Gateway = 192.168.1.254

Figure 3-7. Conn ect th e switch’s R S-232 DB9 port to a serial console.

To configure the switch, follow these steps:

1. Use an RS-232 DB9 cable with a female DB9 connector that has pins 2, 3, and 7.

2. Attach the DB9 female cable connector to the male serial RS-232 DB9 connector on the switch.

3. Attach the other end of the s erial RS-232 DB9 cable to the PC’s serial port, running a terminal emulator supporting a VT100/ANSI terminal with the switch’s serial port default s ettings. For example, Windows98/2000/XP HyperTerminal utility.

NOTE: The switch’s serial port default settings are:

Baud rate: 115200 Stop bits: 1 Data bits: 8 Parity: N Flow control: none

4. After you connect the cables, press the <Enter> key. The login prompt will be shown on the screen. The default username and password are:

Username = admin Password = admin

3.4.2 Set IP Address, Subnet Mask, and Default Gateway IP Address

Refer to Figure 3-7, CLI Management, for details about default IP address settings. First, either configure your PC IP address or change the switch’s IP address, then change the default IP address for the gateway and subnet mask.

For example, your network address is 10.1.1.0, and subnet mask is 255.255.255.0. You can change the switch’s default IP address

192.168.1.1 to 10.1.1.1 and set the subnet mask to be 255.255.255.0. Then, choose your default gateway, for example, 10.1.1.254.

3.4.3 Managing LPB4008A through Ethernet Port

There are three ways to configure and monitor the switch through the switch’s Ethernet port. They are CLI, Web browser, and SNMP manager. The user interface for the last one is NMS dependent and is not explained in this manual. CLI and Web browser management interface are described on the next page.

Default IP Setting: IP address = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 198.168.1.254 Assign a reasonable IP address, for example: IP 192.168.1.100 Subnet Mask = 255.255.255.0 Default Gatewtay = 192.168.1.254

Figure 3-9. Connecting the Ethernet LAN PC to th e switch for network management through an Ethernet port.

Before you communicate with the switch, finish the configuration of the IP address or make sure you know the IP address of the switch. Then, follow the procedures listed below.

Set up a physical path between the configured switch and a PC with a qualified UTP CAT5 cable with RJ-45 connector.

724-746-5500 | blackbox.com

8- and 24-Port Gigabit L2 Managed Power-over-Ethernet (PoE) Switches

NOTE: If the PC connects directly to the switch, you have to setup the same subnet mask between them. The subnet mask may be different for the PC at the remote site.

2. Run CLI or web browser and follow the menu. Refer to Chapters 4 and 5.

Figure 3-10. Login Scre en for Web.

3.5 IP Address Assignment

For IP address configuration, there are three parameters you need to fill in. They are IP address, Subn et Mas k, Default Gateway and DNS.

3.5.1 IP address

The addres s of the network device is used for internetworking communication. Its address structure is shown in Figure 3-11. It is split into predefined address classes or categories.

Each class has its own network range between the network identifier and host identifier in the 32-bit address. Each IP address consists of two parts: network identifier ( address) and host identifier (address). The former indicates the network where the addressed host resides, and the latter indicates the individual host in the network that the address of ho st refers to. The host identifier must be unique in the same LAN. The IP address we used is version 4, known as IPv4.

Classifying addresses divides the IP address into three classes: class A, class B, and class C. The rest of the IP addresses are for multicast and broadcast. The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address/Xl for example,

192.168.1.0/24. Each class has its address range described below.

Class A: Address is les s than 126.255.255.255. There are a total of 126 networks can be defined because the address 0.0.0.0 is reserved for default route and 127.0.0.0/8 is reserved for loopback function.

Class B: The IP address ranges between 128.0.0.0 and 191.255.255.255. Each class B network has a 16-bit network prefix followed by a 16-bit host address. There are 16,384 (214)/16 networks that can be defined with a maximum of 65534 (216-2) hosts per network.

724-746-5500 | blackbox.com

Figure 3-11. IP address structure.

Chapter 3: Installation

Class C: The IP address ranges between 192.0.0.0 and 223.255.255.255. Each class C network has a 24-bit network prefix followed by an 8-bit host address. A total of 2,097,152 (221)/24 networks can be defined with a maximum of 254(28-2) hosts per network.

Class D and E: Class D is a class with the first 4 MSBs (Most Significant Bits) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E is a class with the first 4 MSBs set to 1-1-1-1 and is used for IP broadcast. According to IANA (Internet A ssigned Numbers Authority), three specific IP address blocks (called a private IP address) are reserved for extending an internal network. They are listed below.

Class A 10.0.0.0---10.255.255.255

Class B 172.16.0.0---172.31.255.255

Class C 192.168.0.0---192.168.255.255

Refer to RFC 1597 and RFC 1466 for more information. These documents are available at

3.5.2 Subnet Mask

Subnet mask is the sub-division of a class-based network or a CIDR block. The subnet is used to determine how to split an IP address into the network prefix and the host address. It’s designed to use an IP address more efficiently to manage an IP network.

For a class B network, 128.1.2.3, the default subnet mask may be 255.255.0.0. The first two bytes are all 1s. This means more than 60 thousands of nodes in flat IP addresses will be on the same network. It’s too large to manage practically. If we divide it into smaller networks by extending the network prefix from 16 bits to, say 24 bits, the network uses its third byte to subnet this class B network. The subnet mask is 255.255.255.0; each bit of the first three bytes is 1. The first two bytes are used to identify the class B network, the third byte is used to identify the subnet within this class B network, and the last byte is the host number.

Not all IP addresses are available in the subnetted network. Two special addresses are reserved . They are the addresses with all zeros and all ones for the host number.

As shown in the table below, the subnet mas k with a 25-bit long, 255.255.255.128 address contains 126 members in the subnetted network. The network prefix length equ als the bit number with 1s in that subn et mask. Use this table to count the number of IP addresses matched.

8- and 24-Port Gigabit L2 Managed Power-over-Ethernet (PoE) Switches

According to the scheme above, a subnet mask 255.255.255.0 will partition a network with the class C. A maximum of 254 effective nodes exist in this sub-netted n etwork. It is considered a physical network in an autonomous network, so it owns a n etwork IP address, for example, 168.1.2.0.

With the subnet mask, a bigger network can be divided into smaller networks. If you want to have more than two independent networks in a worknet, you can partition the network. In this case, subnet mask must be applied.

For different network applications, the subnet mask might be 255.255.255.240. This small network accommodates a maximum of 15 nodes.

3.5.3 Default Gateway

For the routed packet, if the destination is not in the routing table, all the traffic is sent to the device with the designated IP address, known as the default router. The gateway setting is used for Trap Events Host only in the switch.

Before assigning an IP address to the switch, check to see what IP address of the network will be connected with the switch. Use the same network address and append your host address to it.

First, type in the IP Address : as shown in Fig. 2-12, enter default IP address “192.168.1.1,” for instance. An IP address such as 192.168.1.x must be set on your PC.

Second, type in the Subnet Mask: as shown in Fig. 2-12, enter “255.255.255.0.” Any subnet mask such a s 255.255.255.x is allowed in this case.

3.5.4 DNS

The Domain Name Server translates human-readable machine names to IP addresses. Every machine on the Internet has a unique IP address. A server has a static IP address. To connect to a server, the client needs to know the IP of the server. However, users generally use the name to connect to the server. Thus, the switch DNS client program (such as a browser) will ask the DNS to resolve the IP address of the named server.

3.6 Typical Application

LPB4008A implements 8 Gigabit Ethernet TP ports with Auto MDI-X and two slots for the removable module supporting fiber connections, including LC and BiDi-LC SFP modules. LPB4024A has 20 Gigaibit Ethernet TP ports with Auto-MDIX and four slots for fiber modules. The switch is suitable for the following applications.

• Edge Site/Remote site application is used in PoE environment (See Figure 3-13).

• Peer-to-peer application is used in two remote offices (See Figure 3-14).

• Office network (See Figure 3-15).

Chapter 4: Operation of Web-based Management

4. Operation of Web-based Management

This chapter instructs you how to configure and manage the LPB4008A or LPB4024A through the web user interface it supports. Through any one port, you can access and monitor the switch status, including MIBs status, port activity, Spanning tree status, port aggregation status, multicast traffic, VLAN and priority status, even illegal access record and so on.

The managed switch’s default values are listed in the table below:

IP Address: 192.168.1.1 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.254 Username: admin Password: admin

After you finish configuring the managed switch in the CLI via the switch’s serial interface, you can browse through the switch. For instance, type

http://192.168.1.1 in the address row in a browser, and the screen shown in Figure 3-1 will appear and ask you to input your

username and password to login and access authentication. The default username and password are both “admin.” The first time you use the serial interface, enter the default username and password, then click the <Login> button. You are now logged in.

If your forgot the manager’s password, click on the “Forgot P assword” option in Web user interface (see Figure 4-1) or input “Ctrl+Z” in the CLI’s login screen (See Figures 4-1–4-2). The system will display the user’s serial number. Write down this serial number and contact Black Box Technical Support at 724-746-5500 for a temporary password. Use this new password as ID and P assword to login to the system temporarily with manager authority. The user can only login to the system one time using the temporary password, so modify your password immediately after you login to the system successfully.

In this login menu, you have to input the complete username and password respectively; the switch will not give you a shortcut to username automatically. This looks inconvenient, but is safer.

The switch supports a simple user management function allowing only one administrator to configure the system at one time. If there are two or more users using administrator’s identity, the switch will allow the only one who logs in first to configure the system. The rest of the users, even with administrator’s identity, can only monitor the s ystem. Users who have no administrator’s identity can only monitor the system. A maximum of three users can login simultaneously to the switch.

To optimize the display effect, we recommend that you use Microsoft IE 6.0 above, Netscape V7.1 above or FireFox V1.00 above with 1024 x 768 resolution. The switch supports a neutral web browser interface.

4.2.3 Time Configuration

The switch provides manual and automatic ways to set the system time via NTP. Manual setting is simple: just input “Year,” “Month,” “Day,” “Hour,” “Minute,” and “Second” within the valid value range indicated for e ach item. If you input an invalid value, for example, 61 minutes, the switch will record the figure as 59.

NTP is a well-known protocol used to synchronize switch system time over a network. NTP, an Internet draft standard formalized in

RFC

1305, uses version 3 protocol. The switch provides four built-in NTP server IP addresses that reside in the Internet and a user-defined NTP

server IP address. The time zone is Greenwich-centered (GMT+/- xx hours).

Function name: Time Function description: Set the system time manually or set it by syncing from time s ervers. Daylight savings time is also supported .

724-746-5500 | blackbox.com

Chapter 4: Operation of Web-based Management

Figure 4-8. System time setting screen.

Parameter description:

Current Time: Shows the system’s current time.

Manual: Click on the Manual button, type in the year, month, day, hour, minute, and second, then press the <Apply> button to adjust the time manually. Valid figures for Y ear, Month, Day, Hour, Minute, and Second are >=2000, 1-12, 1-31, 0-23, 0-59, and 0-59, respectively. If you input an invalid figure and press the <Apply> button, the device will reject the time adjustment request. There is no time zone setting in Manual mode.

Default: Ye ar = 2000, Month = 1, Day = 1, Hour = 0, Minute = 0, Second = 0

NTP: Network Time Protocol (NTP) is used to sync the network time based on Greenwich Mean Time (GMT). If you use the NTP mode and select a built-in NTP time server or manually specify a user-defined NTP server and Time Zone, the switch will sync the time after you press the <Apply> button. Although it synchronizes the time automatically, NTP does not update the time periodically without user input.

The default Time Zone setting is GMT. To select a different time zone, select the time zone first and then perform time sync via NTP. The switch will combine this time zone offset and updated NTP time to calculate the local time. The switch supports configurable time zon e s from –12 to +13 step 1 hour.

Default Time zone: +8 Hrs.

Daylight Saving: Daylight savings time adjusts the time lag or advance in hours, according to the starting date and the ending date. For example, if you set the daylight savings time to be 1 hour, the system time will increase one hour after one minute. And when the time passes over the ending time, the system time will be decrease one hour after one minute.

The switch supports valid configurable daylight savings time from –5 to +5 one hour steps. It does not have to adjust current time to enact daylight s avings time, and you don’t have to set the starting/ending date. If you set daylight savings time to be non-zero, you have to set the starting/ending date as well; otherwise, the daylight savings function will not be activated.

Default for Daylight Saving: 0.

The following parameters are configurable for the Daylight Savings function and described in detail.

Daylight Savings Start: Set when to start daylight savings time.

4.2.4 IP Configuration

IP configuration is one of the most important switch configurations. Without the proper s etting, the network manager will not be able to manage or view the device. The switch supports both manual IP address setting and automatic IP address setting via a DHCP server. When the IP address is changed, you must reboot the switch so the setting will take effect. Use the new IP to browse for web management and CLI management.

Function name: IP Configuration

Function description: Set IP address, subnet mask, default gateway, and DNS for the switch.

Parameter description:

DHCP Setting: DHCP is the abbreviation for Dynamic Host Configuration Protocol. Here DHCP means a switch to turn ON or OFF the function. The switch supports a DHCP client that’s used to get an IP address automatically if you set this function to “Enable.” When enabled, the switch will issue the request to the DHCP server residing in the network to get an IP address. If the DHCP server is down or does not exist, the switch will issue the request and show the IP address requested, until the DHCP server is on. Before getting an IP address from DHC P server, the device will not continue booting. If you set this field to “Disable,” you’ll have to input IP address manually

Default: Disable

IP address: Users can configure the IP settings and fill in new values when the DHCP function is set to “Disable.” Click on the <Apply> button to update.

When DHCP is disabled, Default: 192.168.1.1.

If DHCP is enabled, this field is filled by DHCP server and will not allow u sers to set it manually.

724-746-5500 | blackbox.com

Figure 4-9. IP configuration screen.

Chapter 4: Operation of Web-based Management

Subnet mask: Any IP device in a network must own its IP address, which is composed of a Network address and a Host address; otherwise it can’t communicate with other devices. Subnet mask enables more network addresses. Network classes A, B, and C are too large to fit for almost all networks, so, subnet mask is introduced to solve this problem. Subn et mask us es some bits from a host address and creates an IP address consisting of Network address, Subnet mask number, and host address. This reduces the total IP number of a network able to support, by th e amount of 2 power of the bit number of subn et number (2^[bit number of subnet number]).

Network ID Host ID

Subnet number

Subnet mask is used to set the subnet mask value, which should be the same value as that of the other devices attached to the same network Default: 255.255.255.0

Default gateway: Set an IP address for a gateway to handle those packets that do not meet the routing rules predefined in the device. If a packet does not meet the criteria for another pre-defined path, it must be forwarded to a default router on a default path. This means that any packet with an undefined IP addres s in the routing table will be sent to this device unconditionally.

Default: 192.168.1.254

DNS: Domain Name Server translates between IP address and name address.

The switch supports the DNS client function to re-route the mnemonic name address to the DNS server to get its associated IP address for accessing the Internet. Users can specify a DNS IP address for the switch. With this, the switch can translate a mnemonic name address into an IP address .

There are two ways to specify the IP address of DNS. One is fixed mode, which manually specifies its IP address, the other is dyn amic mode, which is assigned by DHCP server while DHCP is enabled. DNS can help you easily remember the mnemonic address name with meaningful words in it. The default is no assignment of DNS address.

Default: 0.0.0.0

4.2.5 Loop Detection

The loop detection is used to detect the presence of traffic. When the switch receives a pack et’ s (looping detection frame) MAC address that is the same as the one from the port, show Loop is detected. The port will be locked when it receives the looping detection frames. If you want to resume using the locked port, find the looping path, remove it, then select th e locked port and click on “Resume” to enable it.

Function name: Loop Detection

Function description: Displays whether the switch is set up for Loop detection and whether a port has been locked due to loop detection. Also provides the ability to resume normal operation after leaving a loopback path.

Function name: Management Security Configuration

Function description: The switch offers Management Security Configuration. With this function, the manager can easily control the mode in which the user connects to the switch. According to the mode, users can be classified into two types: Those who are able to connect to the switch (Accept) and those who are unable to connect to the switch (Deny). You can place some restrictions on the user conn ect mode. For example, you can decide which VLAN VID will be accepted or denied by the switch. You can also set the switch to accept or deny the users’ IP range, id entify user ports that will connect to the switch, or control and connect to the switch via Http, Telnet or SNMP.

4.2.8 Virtual Stack

Function name: Virtual Stack

Function description: Virtual Stack Management (VSM) is the group management function. It allows you to automatically group switches that are in the same LAN. One switch will be the master device, and the others in this group will become the slave devices.

VSM offers a simple centralized manag ement function. You don’t n eed to remember the address of all devices, since the manager can manage the network using the address of the Master device. Instead of SNMP or Telnet UI, VSM is only available in Web UI (not SNMP or Telnet UI). When one switch becomes the Master, two rows of buttons for group devices will appear on the top of its Web UI. When you press these buttons, users can connect the Web UI of the d evices of the group in the same window without logging in these devices.

The top left button is only for the Master device. The background color of the button you press changes to repres ent that the device is under your management.

NOTE: Logging into the switch via the console will remove the grouping temporarily. Each d evice in the group will be shown as a station

address (the last number of IP Address) + device name on the button (for example, 196_LPB4008A). Otherwise, it will show ” ---- “ if no corresponding device exists.

Once the devices join the group successfully, then they are can be managed via Master device, and user will not be able to manage them via telnet/console/web individually.

Up to 16 devices can be grouped for VSM; however, only one Master is allowed to exist in each group. For Master redundancy, users may configure more than two devices as Master, but the Master device with the smaller MAC value will be the Master one. All 16 devices can become Master devices and back up each other.

Figure 4-14. Virtual stack configuration screen.

Parameter description:

State: Activates or de-activates VSM. The default is Enable.

Role: The switch’s role in the virtual stack. There are two types of roles (master and slave). The default is Master.

Group ID: The group identifier (GID) identifies the VSM. V alid letters are A–Z , a–z, 0–9, “ - “ and “_” characters. The maximum length is 15 characters.

4.3.1 Port Configuration

Port Configuration changes the setting of each port. You can set/reset the several functions. They are described in detail below.

Function name: Port Configuration

Function description: Sets each port’s operation mode. The switch supports three parameters for each port: state, mode, and flow

control.

724-746-5500 | blackbox.com

Figure 4-16. Port configuration screen.

Chapter 4: Operation of Web-based Management

Parameter description:

Speed: S et the speed and duplex of the port. For 1 Gbps fiber, the speed is always 1000 Mbps and full duplex. For twisted pair, the speed/duplex is the combination of speed mode (10/100/1000Mbps), and duplex mode (full duplex and half duplex).

Media type NWay Speed Duplex

1000M TP ON/OFF 10/100/1000M Full for all, Half for 10/100 1000M Fiber ON/OFF 1000M Full

In Auto-negotiation mode, there is no default value. In Forced mode, the default value depends on your setting.

Flow Control: Choose from two flow control modes: Enable and Disable. If flow control is set to Enable, both users can send a PAUSE frame to the transmitting device(s) if the receiving port is too busy to handle more traffic. When flow control is set Disable, the packet is dropped if the traffic is too much to handle.

Maximum Frame: The maximum packet size is 1518–9600 (Bytes) long.

Excessive Collision Mode: If excessive collisions occur when the connection is half-duplex, choose Discard or Restart.

Discard: The “Discard” mode determines whether the MAC drop frames after an excessive collision has occurred. If set to Discard, a frame is dropped after excessive collisions. This conforms to IEEE Std 802.3 half-duplex flow control operation.

Restart: The “Restart” mode determines whether the MAC retransmits frames after an excessive collision has occurred. If set, a frame is not dropped after excessive collisions, but the backoff sequence is restarted. This is a violation of IEEE Std 802.3, but is useful in non-dropping half-duplex flow control operation.

Description: Description of device ports cannot include # % & ‘ + \.

4.3.2 Port Status

The Port Status function gathers each port’s current status information and reports its port number, media, link status, port state, autonegotiation status, speed/duplex, Rx Pause, and Tx Pause . Media type information for the module ports 7 and 8 is also offered (see Figure 4-14).

Function name:

Figure 4-22. VLAN mode.

Parameter description:

VLAN Mode:

Port-based: Port-based VLAN is defined by port. Any packet coming in or going out from any one port of a port-based VLAN will be accepted. No filtering criterion applies in port-bas ed VLAN. The only criterion is the physical port you connect to. For example, a port-based VLAN named PVLAN-1 contains port members Port 1 & 2 & 3 & 4. If you are on port 1, you can communicate with port 2&3&4. If you are on port 5, then you cannot talk to them. Each port-based VLAN must be assigned a group name. This switch can support up to maximal 24 port-based VLAN groups.

Tag-based: Tag-based VLAN identifies its member by VID. This is quite different from port-based VLAN. If there are any more rules in ingress filtering list or egress filtering list, the packet will be screened to determine if it can be forwarded. The switch supports 802.1q. For more details, see Chapter 3.

Each tag-based VLAN must be assigned a VLAN name and a VLAN ID. V alid VLAN IDs are 1–4094. User can create total up to 4094 Tag VLAN groups.

4.4.4 Ports

Function name: VLAN Port Configuration

Function description: In VLAN Tag Rule S etting, users can input the VID number for each port. The VID numbers range from 1 to

4094. Users also can assign ingres s filtering rules to each port. There are two ingress filtering rules that apply to the switch. The Ingress Filtering Rule 1 is “forward only packets with VID matching this port’s configured VID.” The Ingress Filtering Rule 2 is “drop untagged frame.” You can also select each port’s role: Access, Trunk, or Hybrid.

Figure 4-31. VLAN port configuration screen.

Parameter description: Port 1-8: Port number.

VLAN Aware: Forward packets based on IEEE 802.1Q VLAN tag.

Ingress Filtering: Discard other VLAN group packets, only forward packets belonging to this VLAN group.

Frame Type: All: Forward all tagged and untagged packets.

Tagged: Forward tagged packets only and discard untagged packets.

PVID: This PVID rang e is 1–4094. Before you set a number x as PVID, you must create a Tag-based VLAN with VID x. For example, if port x receives an untagged packet, the switch will apply the port x’s PVID (assume it is VID y) to tag this packet, and the packet then will be forwarded as a tagged packet with VID y.

Role: This is a port egress rule. Choose Access, Trunk, or Hybrid. Access means the outgoing packets carry no VLAN tag header. Trunk means the outgoing packets must carry a VLAN tag header. If packets have double VLAN tags, one will be dropped and the other will not be dropped. Hybrid is similar to Trunk, and both will tag-out. When the port is set to Hybrid, its packets will be untagged if the outgoing packets’ tagged VID is the same as the one in this port’s Untagged VID.

Untag VID: Valid range is 1–4094. It works only when Role is s et to Hybrid.

Double Tag: Double-tag mode belongs to the tag-based mode; however, it would treat all frames as untagged, which means that tags with PVID will be added into all packets. Then, these packets will be forwarded as a Tag-based VLAN. The incoming packets with tag will become the double-tag ones. Scroll to en able the function. The default is Disable.

4.7 GVRP

GVRP is an application bas ed on Generic Attribute Registration Protocol (GARP), mainly used to automatically and dynamically maintain the group membership information of the VLANs. The GVRP provides the VLAN registration service through a GARP application. It uses GARP Information Declaration (GID) to maintain the ports associated with their attribute database and GARP Information Propagation (GIP) to communicate among switches and end stations. With GID information and GIP, GVRP state machines maintain the contents of Dynamic VLAN Registration Entries for each VLAN and propagate this information to other GVRP-aware devices to setup and update their knowledge database, the s et of VLANs associated with currently active members, and through which ports these members can be reached.

In GVRP Configuration function folder, there are three functions supported: GVRP Config, GVR P Counter, and GVRP.

4.8 QoS (Quality of Service) Configuration

The switch supports four QoS queues per port with strict or weighted fair queuing scheduling. There are 8 QoS Control Lists (QCL) for advanced programmable QoS classification, based on IEEE 802.1p, Ethertype, VID, IPv4/IPv6 DSCP, and UDP/TCP ports and ranges.

High flexibility in the classification of incoming frames to a QoS class. The QoS classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4 TCP/UDP port numbers, and user priority of tagged frames. This QoS classification mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame is used throughout the device for providing queuing, scheduling, and congestion control guarantees to the frame according to what was configured for that specific QoS class.

The switch supports advanced memory control mechanisms that provide excellent performance of all QoS classes under any traffic scenario, including jumbo frame. A super priority queue has dedicated memory and strict highest priority in the arbitration. The ingress super priority queue allows traffic recognized as CPU traffic to be received and queued for transmission to the CPU even when all the QoS class queues are congested.

4.9 SNMP Configuration

Any Network Management System (NMS) running Simple Network Management Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed devices. The SNMP is a protocol that is used to govern the transfer of information between SNMP manager and agent,. It traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax. The SNMP agent running on the switch responds to the request issued by the SNMP manager.

The NMS issues the trap information. The switch supports a switch to turn on or off the SNMP agent. If you set the field SNMP to “Enable,” the SNMP agent will start. You can access all supported MIB OIDs, including RMON MIB, via SNMP manager. If the field SNMP is set to “Disable,” the SNMP agent will be de-activated, and the related Community Name, Trap Host IP Address , Trap, and all MIB counters will be ignored.

Function name: SNMP Configuration

Function description: This function is used to configure SNMP settings, community name, trap host, and public traps. An SNMP manager must pass the authentication by identifying both community names, then it can access the MIB of the target device. Both parties must have the same community name. Once you complete the setting, click on the <Apply> button, and the s etting takes effect.

724-746-5500 | blackbox.com

Chapter 4: Operation of Web-based Management

Figure 4-61 Community and trap host setting.

Parameters description:

SNMP: Used to activate or deactivate SNMP. The default is Enable.

Get/Set/Trap Community: Community name is used as password for authenticating if the requesting network management unit belongs to the same community group. If they both don’t have the same community name, they don’t belong to the s ame group. In this case, th e requesting network management unit cannot access the device with a different community name via SNMP protocol; If they both have the same community name, they can talk each other.

Community name is u ser-definable with a maximum length of 15 characters and is case-sensitive. No blank sp aces are permitted in the community name string. Any printable character is permitted.

The community name for each function works independently. E ach function has its own community name. The community name for GET only works for the GET function and can’t be applied to other functions such as SET and Trap.

Default SNMP function: Enable

Default community name for GET: public

Default community name for S ET: private

Default community name for Trap: public

Default Set function : Enable

Default trap host IP address: 0.0.0.0

Default port number :162

Trap: 6 trap hosts supported in the switch. Each has its own community name and IP address and is user-definable. To set up a trap host means to create a trap manager by assigning an IP address to host the trap message. The trap host is a network management unit with SNMP manager receiving the trap message from the managed switch with SNMP agent issuing the trap message. 6 trap hosts can prevent losing an important trap mess age.

For each public trap, the switch supports the trap event Cold Start, Warm Start, Link Down, Link Up, and Authentication Failure Trap. They can be enabled or disabled individually. When enabled, the corresponding trap will actively s end a trap message to the trap host

8- and 24-Port Gigabit L2 Managed Power-over-Ethernet (PoE) Switches

when a trap occurs. If all public trap s are disabled, no public trap message will be sent. The Enterprise (no. 6 ) trap is classified as a private trap, and is listed in the Trap Alarm Configuration function folder. Default for all public traps: Enable.

4.10 ACL

The LPB4008A switch access control list (ACL) is probably the most commonly used object in the IOS. It is used for packet filtering but also for selecting types of traffic to be analyzed, forwarded, or influenced in some way.

The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC, and VLAN parameters, etc. Here we will just go over the standard and extended access lists for TCP/IP . As you create ACEs for ingress classification, you can assign a policy for each port. The policy number is 1–8 ; however, each policy can be applied to any port. This makes it very easy to determine what type of ACL policy you will be working with.

4.10.1 Ports

Function name: ACL Port Configuration

Function description: The switch ACL function supports up to 128 Access Control Entries (ACEs), using 128 shared ACEs for ingress classification. You can create an ACE and assign this ACE for each port with <Any>, assign this ACE for a policy, or assign this ACE for a port. Th ere are 8 policies, each port can s elect one of policy, then decides which of the following actions would take according to the packet’s IPv4, EtherType, ARP Protocol, MAC Parameters, and VLAN parameters:

Packet Deny or Permit

Rate Limiter (Unit: pps)

Port Copy (1–8)

Parameter description:

Port #: Port number: 1–8

Policy ID: Policy ID range: 1–8

Action: Permit or Deny forwarding the met ACL packets

Rate Limiter ID: Disabled: Disable Rate Limitation

Rate Limiter ID Range: 1~16. To select one of rate limiter ID for this port, it will limit met ACL packets by rate limiter ID configuration.

724-746-5500 | blackbox.com

Figure 4-62. ACL ports configuration.

Chapter 4: Operation of Web-based Management

Port Copy: Disabled: Disable to copy the met ACL packets to a specific port.

Port number: 1–8. Copy the met ACL packets to the selected port.

Counter: The counter will increase from its initial value 0, when this port receives one of the met ACL packets, the counter value will increase +1.

4.10.2 Rate Limiters

Function name:

ACL Rate Limiter Configuration

Function description:

There are 16 rate limiter IDs. You can assign one limiter ID for each port. The rate limit configuration unit is Packet Per Second (pps).

Parameter description:

Rate Limiter ID: ID Range: 1–16

Rate(pps): 1/2/4/8/16/32/64/128/256/512/1K/2K/4K/8K/16K/ 32K/64K/128K/256K/512K/1024K

Function name: ACL Rate Limiter Configuration

Function description: The switch ACL function supports up to 128 Access Control Entries (ACEs), using the sh ared 128 ACEs for ingress classification. You can create an ACE and assign this ACE for each port with <Any>, assign this ACE for a policy, or assign this ACE for a port. There are 8 policies. Each port can select one policy, then decide which Permit/Deny, Rate Limitation, and Port Copy actions to take according to the ACL configuration packet’s IPv4, EtherType, ARP Protocol, MAC Parameters, and VLAN parameters.
