1.2 Product Description  
Full-Functioned / Advanced Features Layer 2 Managed Switch for Enterprise and Campus Networking  
The PLANET SGSD-1022 / SGSW-2840 is a 8 / 24-Port 10/100Mbps Fast Ethernet Switch with 2 / 4-Port Gigabit TP/ SFP 
Combo interfaces, which boasts high performance switch architecture. That is capable of providing non-blocking switch fabric 
and wire-speed throughput as high as 12.8 Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to 
increase bandwidth demands. Its four built-in GbE uplink ports also offer incredible extensibility, flexibility and connectivity to the 
core switch or servers.

User’s Manual of SGSD-1022 / SGSD-1022P 
SGSW-2840 / SGSW-2840P 
Robust Layer 2 Features 
The SGSW-2840 can be programmed for basic switch management functions such as port speed configuration, Port 
aggregation, VLAN, Spanning Tree protocol, QoS, bandwidth control and IGMP Snooping. It provides IEEE 802.1Q Tagged 
VLAN and the VLAN groups allowed on the SGSW-2840 will be maximally up to 256. Via aggregation of supporting port, the 
SGSW-2840 allows the operation of high-speed trunk combining multiple ports. Maximum up to 8 ports can be assigned for 12 
trunk groups and it supports fail-over as well. 
Excellent Traffic Control 
The SGSx-series Managed Switch is loaded with powerful traffic management and QoS features to enhance services offered by 
telecoms. The functionality includes QoS features such as wire-speed Layer 4 traffic classifiers and bandwidth limiting 
applications that are particular useful for multi-tenant unit, multi business unit, Telco, or Network Service Provider. It also 
empowers the enterprises to take full advantages of the limited network resources and guarantees the best performance in VoIP 
and Video conferencing transmission.  
Efficient IP Stacking Management 
The SGSW-2840 supports IP Stacking function that helps network managers to easily configure up to 36 switches in the same 
series via one single IP address instead of connecting and setting each unit one by one. For efficient management, the 
SGSx-series Managed Ethernet Switch is equipped with console, WEB and SNMP management interfaces. With its built-in 
Web-based management, it offers an easy-to-use, platform-independent management and configuration facility. It supports 
standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software 
as well. For text-based management, the SGSx-series Managed Switch can also be accessed via Telnet and the console port. 
Moreover, it offers secure remote management by supporting SSL and SSH connection which encrypt the packet content at 
each session. 
Powerful Security 
The SGSx-series Managed Switc offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its 
protection mechanism also comprises port-based IEEE 802.1x user and device authentication. The port-security is effective in 
limiting the numbers of clients pass through so that network administrators can now construct highly secured corporate 
networks with considerably less time and effort than before. 
Flexibility and Extension solution 
The four mini-GBIC slots are compatible with 1000Base-SX/LX and WDM SFP (Small Form Factor Pluggable) fiber-optic 
modules. The distance can be extended from 550 meters (Multi-Mode fiber cable) or up to 10/30/50/70/120 kilometers 
(Single-Mode fiber or WDM fiber cable). They are well suited for applications within the enterprises’ data centers and 
distributions.

2.2.3 Installing the SFP transceiver  
The sections describe how to insert an SFP transceiver into an SFP slot. 
The SFP transceivers are hot-pluggable and hot-swappable. You can plug-in and out the transceiver to/from any SFP port 
without having to power down the Managed Switch. As the Figure 2-20  appears. 
Figure 2-20 Plug-in the SFP transceiver  
Approved PLANET SFP Transceivers 
PLANET Managed Switch supports both Single mode and Multi-mode SFP transceiver. The following list of approved PLANET 
SFP transceivers is correct at the time of publication: 
■MGB-SX SFP (1000BASE-SX SFP transceiver )   
■MGB-LX SFP (1000BASE-LX SFP transceiver )  
It recommends using PLANET SFPs on the Managed Switch. If you insert a SFP transceiver that is 
not supported, the Managed Switch will not recognize it. 
Before connect the other Managed Switches, workstation or Media Converter. 
1.   Make sure both side of the SFP transceiver are with the same media type, for example: 1000Base-SX to 1000Base-SX, 
1000Bas-LX to 1000Base-LX. 
2.   Check the fiber-optic cable type match the SFP transceiver model. 
¾  To connect to 1000Base-SX SFP transceiver, use the Multi-mode fiber cable- with one side must be male duplex LC 
connector type. 
¾  To connect to 1000Base-LX SFP transceiver, use the Single-mode fiber cable-with one side must be male duplex LC 
connector type.

Connect the fiber cable 
1.   Attach the duplex LC connector on the network cable into the SFP transceiver. 
2.   Connect the other end of the cable to a device – switches with SFP installed, fiber NIC on a workstation or a Media 
Converter.. 
3.   Check the LNK/ACT LED of the SFP slot on the front of the Managed Switch. Ensure that the SFP transceiver is operating 
correctly. 
4.   Check the Link mode of the SFP port if the link failed. Co works with some fiber-NICs or Media Converters, set the Link 
mode to “1000 Force” is needed. 
Remove the transceiver module 
1.   Make sure there is no network activity by consult or check with the network administrator. Or through the management 
interface of the switch/converter (if available) to disable the port in advance. 
2.   Remove the Fiber Optic Cable gently. 
3.   Turn the handle of the MGB module to horizontal. 
4.   Pull out the module gently through the handle.

3.2 Management Access Overview  
The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods: 
 An console   
   Web browser  interface 
 An  SNMP-based network management application   
The administration console and Web browser interface support are embedded in the Managed Switch software and are 
available for immediate use. Each of these management methods has their own advantages. Table 3-1 compares the three 
management methods. 
Method   Advantages   Disadvantages 
Console 
Web Browser 
SNMP Agent 
• No IP address or subnet needed  
• Text-based  
• Telnet functionality and HyperTerminal  
built into Windows 
95/98/NT/2000/ME/XP operating 
systems 
• Secure  
• Ideal for configuring the switch remotely 
• Compatible with all popular browsers  
• Can be accessed from any location  
• Most visually appealing  
• Communicates with switch functions at  
the MIB level 
• Based on open standards  
• Must be near switch or use dial-up connection 
• Not convenient for remote users  
• Modem connection may prove to be unreliable  
or slow 
•  Security can be compromised (hackers need 
only know the IP address and subnet mask) 
• May encounter lag times on poor connections 
• Requires SNMP manager software  
• Least visually appealing of all three methods  
• Some settings require calculations  
• Security can be compromised (hackers need  
only know the community name) 
Table 3-1 Management Methods Comparison  
3.3 Administration Console  
The administration console is an internal, character-oriented, and command line user interface for performing system 
administration such as displaying statistics or changing option settings. Using this method, you can view the administration 
console from a terminal, personal computer, Apple Macintosh, or workstation connected to the switch's console (serial) port.  
There are two ways to use this management method: via direct access or modem port access. The following sections describe 
these methods. For more information about using the console, refer to Chapter 5 Command Line Interface Console  
Management .

SGSW-2840 / SGSW-2840P 
Figure 3-1 Console management  
Direct Access  
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a 
terminal-emulation program (such as HyperTerminal ) to the Managed Switch console (serial) port. 
When using this management method, a straight DB9 RS-232 cable  is required to connect the switch to the PC. After making 
this connection, configure the terminal-emulation program to use the following parameters: 
The default parameters are: 
   9600 bps  
   8 data bits  
   No parity  
   1 stop bit  
Figure 3-2  Terminal parameter settings 
You can change these settings, if desired, after you log on. This management method is often preferred because you can 
remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, 
regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any 
terminal-emulation program for connecting to the terminal serial port. A workstation attachment under UNIX can use an emulator 
such as TIP.

3.4 Web Management  
The Managed Switch provides a browser interface that lets you configure and manage the switch remotely. After you set up your 
IP address for the switch, you can access the Managed Switch's Web interface applications directly in your Web browser by 
entering the IP address of the Managed Switch. You can then use your Web browser to list and manage the Managed Switch 
configuration parameters from one central location, just as if you were directly connected to the Managed Switch's console port. 
Web Management requires either Microsoft Internet Explorer 6.0  or later, Safari  or Mozilla Firefox 1.5  or later. 
Figure 3-3 Web management  
3.5 SNMP-Based Network Management   
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network 
Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP 
agent on the switch and the SNMP Network Management Station to use the same community string . This management 
method, in fact, uses two community strings: the get community  string and the set community  string. If the SNMP Net-work 
management Station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get 
community string, it can only read MIBs. The default gets and sets community strings for the Managed Switch are public.

SGSW-2840 / SGSW-2840P 
3.6 Protocols  
The Managed Switch supports the following protocols: 
   Virtual terminal protocols, such as Telnet 
   Simple Network Management Protocol (SNMP) 
3.6.1 Virtual Terminal Protocols  
A virtual terminal protocol is a software program, such as Telne t , that allows you to establish a management session from a 
Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on 
the Managed Switch before you can establish access to it with a virtual terminal protocol. 
Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal directly 
to the console (serial) port.  
3.6.2 SNMP Protocol  
Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor IP networks. SNMP 
supports transaction-based queries that allow the protocol to format messages and to transmit information between reporting 
devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode 
service. 
3.6.3 Management Architecture  
All of the management application modules use the same Messaging Application Programming Interface (MAPI). By unifying 
management methods with a single MAPI, configuration parameters set using one method (console port, for example) are 
immediately displayable by the other management methods (for example, SNMP agent of Web browser). 
The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that the 
Managed Switch is compatible with, and will interoperate with other solutions that adhere to the same open standard.

4. WEB CONFIGURATION  
This section introduces the configuration and functions of the Web-Based management. 
About Web-based Management 
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the 
network through a standard browser such as Microsoft Internet Explorer. 
The Web-Based Management supports Internet Explorer 6.0. It is based on Java Applets with an aim to reduce network 
bandwidth consumption, enhance access speed and present an easy viewing screen. 
By default, IE6.0 or later version does not allow Java Applets to open sockets. The user has to 
explicitly modify the browser setting to enable Java Applets to use network ports. 
The Managed Switch can be configured through an Ethernet connection, make sure the manager PC must be set on same the 
IP subnet address with the Managed Switch.  
For example, the default IP address of the SGSD / SGSW Managed Switch is 192.168.0.100 , then the manager PC should be 
set at 192.168.0.x  (where x is a number between 1 and 254, except 100), and the default subnet mask is 255.255.255.0.  
If you have changed the default IP address of the Managed Switch to 192.168.1.1 with subnet mask 255.255.255.0 via console, 
then the manager PC should be set at 192.168.1.x (where x is a number between 2 and 254) to do the relative configuration on 
manager PC.

Object   Description 
•  Extended Multicast  
Filtering Services 
• Traffic Classes  
• VLAN Learning  
• Configurable PVID  
Tagging 
•  Local VLAN Capable  
This Managed Switch does not support the filtering of individual multicast 
addresses based on GMRP (GARP Multicast Registration Protocol) . 
This Managed Switch provides mapping of user priorities to multiple traffic 
classes. (Refer to “Class of Service Configuration ”) 
This Managed Switch uses Independent VLAN Learning (IVL) , where each port 
maintains its own filtering database. 
This Managed Switch allows you to override the default Port VLAN ID (PVID  
used in frame tags) and egress status (VLAN-Tagged or Untagged) on each port. 
(Refer to “VLAN Configuration ”.) 
This Managed Switch does not support multiple local bridges outside of the 
scope of 802.1Q defined VLANs. 
•  GMRP  
GARP Multicast Registration Protocol (GMRP) allows network devices to  
register endstations with multicast groups. This Managed Switch does not  
support GMRP; it uses the Internet Group Management Protocol (IGMP) to 
provide automatic multicast filtering.

4.2.4 IP Configuration  
This section describes how to configure an IP interface for management access over the network. The IP address for the stack 
is obtained via DHCP by default. To manually configure an address, you need to change the Managed Switch’s default settings 
to values that are compatible with your network. You may also need to an establish a default gateway between the stack and 
management stations that exist on another network segment.  
You can manually configure a specific IP address, or direct the device to obtain an address from a BOOTP or DHCP server. 
Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. 
Figure 4-2-4 IP Configuration screenshot  
Object   Description 
• Management VLAN  
• IP Address Mode  
ID of the configured VLAN (1-4094). This is the only VLAN through which you 
can manage the Managed Switch.  
By default, all ports on the Managed Switch are members of VLAN 1. However, 
the management station can be attached to a port belonging to any VLAN, as 
long as that VLAN has been assigned an IP address. 
Specifies whether IP functionality is enabled via : 
   Static  - manual configuration 
   DHCP  - Dynamic Host Configuration Protocol 
   BOOTP  - Boot Protocol 
If DHCP/BOOTP is enabled, IP will not function until a reply has been received 
from the server. Requests will be broadcast periodically by the switch for an IP 
address. (DHCP/BOOTP values can include the IP address, subnet mask, and 
default gateway.) 
•  IP Address  
Address of the VLAN interface that is allowed management access. Valid IP 
addresses consist of four numbers, 0 to 255, separated by periods.  
(Default: 192.168.0.100 ) 
59
Page 60
User’s Manual of SGSD-1022 / SGSD-1022P 
SGSW-2840 / SGSW-2840P 
•  Subnet Mask  
This mask identifies the host address bits used for routing to specific subnets.  
(Default: 255.255.255.0 ) 
• Gateway IP address  
• MAC Address  
• Restart DHCP  
If you lose your management connection, use a console connection and enter “ show ip 
interface” to determine the new switch address.  
    Manual Configuration   
1. Click System, IP Configuration.  
2. Select the VLAN through which the management station is attached, set the IP Address Mode to “Static ,” enter the IP 
address, subnet mask and gateway, then click Apply.  
IP address of the gateway router between this device and management stations 
that exist on other network segments.  
(Default: 0.0.0.0 ) 
The physical layer address for this Managed Switch. 
Requests a new IP address from the DHCP server. 
    Using DHCP/BOOTP   
If your network provides DHCP/BOOTP services, you can configure the Managed Switch to be dynamically configured by these 
services. 
1. Click System, IP Configuration.  
2. Specify the VLAN to which the management station is attached, set the IP Address Mode to DHCP  or BOOTP . 
3. Click Apply to save your changes.  
4. Then click Restart DHCP to immediately request a new address.   
The Managed Switch will also broadcast a request for IP configuration settings on each 
power reset. 
    Renewing DCHP   
DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to 
another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a 
client request to restart DHCP service via the CLI.  
1. If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the web 
interface. 
2. You can only restart DHCP service via the Web interface if the current address is still available.

4.2.5 Jumbo Frames  
The Managed Switch provides more efficient throughput for large sequential data transfers by supporting jumbo frames up to 
9216 bytes . Compared to standard Ethernet frames that run only up to 1.5 KB, using jumbo frames significantly reduces the 
per-packet overhead required to process protocol encapsulation fields.  
The Jumbo Frames configure screen in Figure 4-2-5  appears.

4.2.8.1 System Log Configuration   
The system can be configured to send debug and error messages to a logging process. This logging process controls the type 
of error messages that are stored in switch memory or sent to a remote syslog server. 
The system allows you to enable or disable event logging, and specify which levels are logged to RAM or flash memory.  
Severe error messages that are logged to flash memory are permanently stored in the switch to assist in troubleshooting 
network problems. Up to 4096 log entries can be stored in the flash memory, with the oldest entries being overwritten first when 
the available log memory (256 kilobytes) has been exceeded.  
The System Logs page allows you to configure and limit system messages that are logged to flash or RAM memory. The default 
is for event levels 0 to 3 to be logged to flash and levels 0 to 6 to be logged to RAM. 
The following table lists the event levels of the Managed Switch:

4.2.9 UPNP  
Universal Plug and Play (UPnP) is a set of protocols that allows devices to connect seamlessly and simplifies the deployment  
of home and office networks. UPnP achieves this by issuing UPnP device control protocols designed upon open, Internet-based 
communication standards. 
The first step in UPnP networking is discovery. When a device is added to the network, the UPnP discovery protocol allows that 
device to broadcast its services to control points on the network. Similarly, when a control point is added to the network, the 
UPnP discovery protocol allows that control point to search for UPnP enabled devices on the network. 
Once a control point has discovered a device its next step is to learn more about the device and its capabilities by retrieving the 
device’s description from the URL provided by the device in the discovery message. After a control point has retrieved a 
description of the device, it can send actions to the devices service. To do this, a control point sends a suitable control message 
to the control URL for the service (provided in the device description). 
When a device is known to the control point, periodic event notification messages are sent. An UPnP description for a service 
includes a list of actions the service responds to and a list of variables that model the state of the service at run time. 
If a device has a URL for presentation, then the control point can retrieve a page from this URL, load the page into a Web 
browser and depending on the capabilities of the page, allows a user to control the device and/or view device status. 
UPnP Configuration 
This page allows you to enable or disable UPnP, and to set time out values.

4.2.11 SNTP  
Simple Network Time Protocol (SNTP) allows the Managed Switch to set its internal clock based on periodic updates from a  
time server (SNTP or NTP). Maintaining an accurate time on the Managed Switch enables the system log to record meaningful 
dates and times for event entries. You can also set the clock manually. If the clock is not set, the Managed Switch will only 
record the time from the factory default set at the last bootup.  
When the SNTP client is enabled, the switch periodically sends a request for a time update to a configured time server. You can 
configure up to three time server IP addresses. The switch will attempt to poll each server in the configured sequence. 
4.2.11.1 SNTP Configuration  
You can configure the Managed Switch to send time synchronization requests to specific time servers (i.e., client mode), update 
its clock based on broadcasts from time servers, or use both methods. When both methods are enabled, the Managed Switch 
will update its clock using information broadcast from time servers, but will query the specified server(s) if a broadcast is not 
received with the polling interval. 
Figure 4-2-25  SNTP Configuration page screenshot 
The page includes the following fields: 
Object   Description 
•  SNTP Client  
Configures the Managed Switch to operate as an SNTP client. This requires at 
least one time server to be specified in the SNTP Server field.

• SNTP Poll Interval  
• SNTP Server  
Sets the interval between sending requests for a time update from a time server. 
(Range: 16-16384 seconds; Default: 16 seconds) 
Sets the IP address for up to three time servers. The Managed Switch attempts 
to update the time from the first server, if this fails it attempts an update from the 
next server in the sequence.

4.2.12 LLDP  
Link Layer Discovery Protocol (LLDP) is used to discover basic information about neighboring devices on the local broadcast  
domain. LLDP is a Layer 2 protocol that uses periodic broadcasts to advertise information about the sending device. Advertised 
information is represented in Type Length Value (TLV) format according to the IEEE 802.1ab standard, and can include details  
such as device identification, capabilities and configuration settings. LLDP also defines how to store and maintain information 
gathered about the neighboring network nodes it discovers.  
Link Layer Discovery Protocol - Media Endpoint Discovery (LLDP-MED)  is an extension of LLDP intended for managing 
endpoint devices such as Voice over IP phones and network switches. The LLDP-MED TLVs advertise information such as 
network policy, power, inventory, and device location details. LLDP and LLDP-MED information can be used by SNMP 
applications to simplify troubleshooting, enhance network management, and maintain an accurate network topology.  
4.2.12.1 LLDP Configuration  
Setting LLDP Timing Attributes  
Use the LLDP Configuration screen to set attributes for general functions such as globally enabling LLDP on the Managed 
Switch, setting the message ageout time, and setting the frequency for broadcasting general advertisements or reports about 
changes in the LLDP MIB.  
Figure 4-2-27  LLDP Configuration page screenshot 
The page includes the following fields: 
Object   Description 
• LLDP  
• Transmission Interval  
Enables LLDP globally on the switch.  
Default: Enabled  
Configures the periodic transmit interval for LLDP advertisements. 
Range: 5-32768seconds;  
82
Page 83
User’s Manual of SGSD-1022 / SGSD-1022P 
SGSW-2840 / SGSW-2840P 
Default: 30  seconds 
This attribute must comply with the following rule: 
(Transmission Interval * Hold Time Multiplier) ≤ 65536, and Transmission Interval 
>= (4 * Delay Interval) 
• Hold Time Multiplier  
• Delay Interval  
Configures the time-to-live (TTL)  value sent in LLDP advertisements as shown 
in the formula below.  
Range: 2-10;  
Default: 4  
The time-to-live tells the receiving LLDP agent how long to retain all information 
pertaining to the sending LLDP agent if it does not transmit updates in a timely 
manner. 
TTL in seconds is based on the following rule: 
(Transmission Interval * Holdtime Multiplier) ≤  65536. 
Therefore, the default TTL is 4*30 = 120 seconds.  
Configures a delay between the successive transmission of advertisements 
initiated by a change in local LLDP MIB variables.  
Range: 1-8192 seconds;  
Default: 2  seconds 
• Reinitialization Delay  
• Notification Interval  
The transmit delay is used to prevent a series of successive LLDP transmissions 
during a short period of rapid changes in local LLDP MIB objects, and to increase 
the probability that multiple, rather than single changes, are reported in each 
transmission. 
This attribute must comply with the rule: 
 (4 * Delay Interval)  ≤Transmission Interval  
Configures the delay before attempting to re-initialize after LLDP ports are 
disabled or the link goes down.  
Range: 1-10 seconds;  
Default: 2  seconds 
When LLDP is re-initialized on a port, all information in the remote systems LLDP 
MIB associated with this port is deleted. 
Configures the allowed interval for sending SNMP notifications about LLDP MIB 
changes. 
Range: 5-3600 seconds;

Page 84
User’s Manual of SGSD-1022 / SGSD-1022P 
SGSW-2840 / SGSW-2840P 
Default: 5  seconds 
This parameter only applies to SNMP applications which use data stored in the 
LLDP MIB for network monitoring or management. Information about changes in 
LLDP neighbors that occur between SNMP notifications is not transmitted. Only 
state changes that exist at the time of a notification are included in the 
transmission. An SNMP agent should therefore periodically check the value of 
lldpStatsRemTableLastChangeTime to detect any lldpRemTablesChange 
notification-events missed due to throttling or transmission loss. 
•  MED Fast Start Count  
Configures the amount of LLDP MED Fast Start LLDPDUs to transmit during the 
activation process of the LLDP-MED Fast Start mechanisim.  
Range: 1-10 packets;  
Default: 4  packets 
The MED Fast Start Count parameter is part of the timer which ensures that the 
LLDP-MED Fast Start mechanism is active for the port. LLDP-MED Fast Start is 
critical to the timely startup of LLDP, and therefore integral to the rapid availability 
of Emergency Call Service. 
4.2.12.2 LLDP Port Configuration  
Use the LLDP Port Configuration to specify the message attributes for individual interfaces, including whether messages are 
transmitted, received, or both transmitted and received, whether SNMP notifications are sent, and the type of information 
advertised.

MIB. 
Since there are typically a number of different addresses associated with a Layer 
3 device, an individual LLDP PDU may contain more than one management 
address TLV.  
Every management address TLV that reports an address that is accessible on a 
port and protocol VLAN through the particular port should be accompanied by a 
port and protocol VLAN TLV that indicates the VLAN identifier (VID) associated 
with the management address reported by this TLV.  
-System Name  – The system name is taken from the sysName object in RFC 
3418, which contains the system’s administratively assigned name. To configure 
the system name, see “Displaying System Information”.  
-System Capabilities  – The system capabilities identifies the primary function(s) 
of the system and whether or not these primary functions are enabled. The 
information advertised by this TLV is described in IEEE 802.1AB. 
Configures the information included in the MED TLV field of advertised 
messages.

mismatches on a port. Improper network policy configurations frequently result in 
voice quality degradation or complete service disruption. 
-Location – This option advertises location identification details.   
-Extended Power – This option advertises extended Power-over-Ethernet  
capability details, such as power availability from the switch, and power state of 
the switch, including whether the switch is operating from primary or backup 
power (the Endpoint Device could use this information to decide to enter power 
conservation mode). Note that this device does not support PoE capabilities.  
-Inventory  – This option advertises device details useful for inventory  
management, such as manufacturer, model, software version and other 
pertinent information.

4.3 Simple Network Management Protocol  
Simple Network Management Protocol (SNMP) is a communication protocol designed specifically for managing devices on a  
network. Equipment commonly managed with SNMP includes switches, routers and host computers. SNMP is typically used to 
configure these devices for proper operation in a network environment, as well as to monitor them to evaluate performance or 
detect potential problems.  
Managed devices supporting SNMP contain software, which runs locally on the device and is referred to as an agent. A defined 
set of variables, known as managed objects, is maintained by the SNMP agent and used to manage the device. These objects 
are defined in a Management Information Base (MIB)  that provides a standard presentation of the information controlled by 
the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the 
network. 
The Managed Switch includes an onboard agent that supports SNMP versions 1, 2c, and 3. This agent continuously monitors 
the status of the Managed Switch hardware, as well as the traffic passing through its ports. A network management station can 
access this information using software such as HP OpenView. Access to the onboard agent from clients using SNMP v1 and v2c 
is controlled by community strings. To communicate with the switch, the management station must first submit a valid 
community string for authentication.  
Access to the switch using from clients using SNMPv3 provides additional security features that cover message integrity, 
authentication, and encryption; as well as controlling user access to specific areas of the MIB tree.  
The SNMPv3 security structure consists of security models, with each model having it’s own security levels. There are three 
security models defined, SNMPv1, SNMPv2c , and SNMPv3 . Users are assigned to “groups ” that are defined by a security 
model and specified security levels. Each group also has a defined security access to set of MIB objects for reading and writing, 
which are known as “views .” The switch has a default view (all MIB objects) and default groups defined for security models v1 
and v2c. The following table shows the security models and levels available and the system default settings.  
Model   Level   Group   Read View  Write View  Notify View   Security 
v1   noAuthNoPriv    public (read only)  defaultview   none   none   Community string only 
v1   noAuthNoPriv  private(read/write)  defaultview   defaultview   none    Community string only 
v1   noAuthNoPriv  user defined   user defined user defined   user defined  Community string only 
v2c   noAuthNoPriv  public (read only)   defaultview   none   none   Community string only 
v2c   noAuthNoPriv  private (read/write)   defaultview defaultview none   Community 
v2c   noAuthNoPriv  user defined   user defined user defined   user defined  Community string only 
v3   noAuthNoPriv  user defined   user defined user defined   user defined  A user name match only 
v3   AuthNoPriv   user defined   user defined   user defined   user defined  Provides user 
authentication via MD5

The predefined default groups and view can be deleted from the system. You can then 
define customized groups and views for the SNMP clients that require access.

Capability 
• Community String  
• Access Mode  
The switch supports up to five community strings. 
A community string that acts like a password and permits access to the SNMP 
protocol. 
Default strings: “public ” (read-only), “private ” (read/write)  
Range: 1-32 characters, case sensitive 
Specifies the access rights for the community string:  
•  Read-Only  – Authorized management stations are only able to retrieve MIB  
objects. 
•  Read/Write  – Authorized management stations are able to both retrieve and  
modify MIB objects. 
4.3.2.2 SNMP Trap Management  
Traps indicating status changes are issued by the switch to specified trap managers. You must specify trap managers so that 
key events are reported by this switch to your management station (using network management platforms such as HP 
OpenView). You can specify up to five management stations that will receive authentication failure messages and other trap 
messages from the Managed Switch.  
- You can enable or disable authentication messages via the Web interface. 
- You can enable or disable authentication messages, link-up-down messages, or all notification types via the CLI.

User’s Manual of SGSD-1022 / SGSD-1022P 
SGSW-2840 / SGSW-2840P 
If you specify an SNMP Version 3 host, then the “Trap Manager Community String” is interpreted as an SNMP user name. If you  
use V3 authentication or encryption options (authNoPriv or authPriv), the user name must first be defined in the SNMPv3 Users 
page. Otherwise, the authentication password and/or privacy password will not exist, and the switch will not authorize SNMP 
access for the host. However, if you specify a V3 host with the no authentication (noAuth) option, an SNMP user account will be 
automatically generated, and the switch will authorize SNMP access for the host.  
Notifications are issued by the switch as trap messages by default. The recipient of a trap message does not send a response to 
the switch. Traps are therefore not as reliable as inform messages, which include a request for acknowledgement of receipt. 
Informs can be used to ensure that critical information is received by the host. However, note that informs consume more 
system resources because they must be kept in memory until a response is received. Informs also add to network traffic. You 
should consider these effects when deciding whether to issue notifications as traps or informs.  
To send an inform to a SNMPv2c host, complete these steps:  
1.   Enable the SNMP agent.  
2.   Enable trap informs as described in the following pages.  
3.   Create a view with the required notification messages.  
4.   Create a group that includes the required notify view. 
To send an inform to a SNMPv3 host, complete these steps: 
1.   Enable the SNMP agent.  
2.   Enable trap informs as described in the following pages.  
3.   Create a view with the required notification messages.  
4.   Create a group that includes the required notify view.  
5.   Specify a remote engine ID where the user resides.  
6.   Then configure a remote user.
