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 administration console
Web browser interface
An external 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
No IP address or subnet needed
Text-based
Telnet functionality and HyperTerminal
built into Windows
95/98/NT/2000/ME/XP operating
systems
Secure
Must be near switch or use dial-up connection
Not convenient for remote users
Modem connection may prove to be unreliable
or slow
Web Browser
Ideal for configuring the switch remotely
Compatible with all popular browsers
Can be accessed from any location
User friendly GUI
Security can be compromised (hackers need
only know the IP address and subnet mask)
May encounter lag times on poor connections
SNMP Agent
Communicates with switch functions at
the MIB level
Based on open standards
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.
Page 40
40
Figure 3-1 Console Management Diagram
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:
115200 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
Page 41
User’s Manual of NS3550-24T/4S
41
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 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. 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.
Figure 3-3 Web Management Diagram
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 3-4 Web Main Screen of Managed Switch
Page 42
42
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.

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 7.0. 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, IE7.0 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 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.
Figure 4-1-1 Web Management Diagram
Page 44

UPnP is an acronym for Universal Plug and Play. The goals of UPnP are to allow devices to connect seamlessly and to simplify
the implementation of networks in the home (data sharing, communications, and entertainment) and in corporate environments
for simplified installation of computer components. The UPnP Configuration screen is shown in Figure 4-2-9.
Figure 4-2-9 UPnP
Configuration Page Screenshot
The page includes the following fields:
Object Description
Mode
Indicates the UPnP operation mode. Possible modes are:
Enabled: Enable UPnP mode operation.
Disabled: Disable UPnP mode operation.
When the mode is enabled, two ACEs are added automatically to trap UPNP
related packets to CPU. The ACEs are automatically removed when the mode is
disabled.
TTL
The TTL value is used by UPnP to send SSDP advertisement messages. Valid
values are in the range 1 to 255.
Advertising Duration
The duration, carried in SSDP packets, is used to inform a control point or control
points how often it or they should receive a SSDP advertisement message from
this switch. If a control point does not receive any message within the duration, it
will think that the switch no longer exists. Due to the unreliable nature of UDP, in
the standard it is recommended that such refreshing of advertisements to be done
at less than one-half of the advertising duration. In the implementation, the switch
sends SSDP messages periodically at the interval one-half of the advertising
duration minus 30 seconds. Valid values are in the range 100 to 86400.

4.2.8 DHCP Relay
Configure DHCP Relay on this page. DHCP Relay is used to forward and to transfer DHCP messages between the clients and
the server when they are not on the same subnet domain.
The DHCP option 82 enables a DHCP relay agent to insert specific information into DHCP request packet when forwarding
client DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when forwarding server
DHCP packets to a DHCP client. The DHCP server can use this information to implement IP address or other assignment policies.
Specifically the option works by setting two sub-options:
Circuit ID (option 1)
Remote ID (option2).
The Circuit ID sub-option is supposed to include information specific to which circuit the request came in on.
The Remote ID sub-option was designed to carry information relating to the remote host end of the circuit.
Page 61
User’s Manual of NS3550-24T/4S

The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of
"vlan_id" is the first two bytes represent the VLAN ID. The parameter of "module_id" is the third byte for the module ID. The
parameter of "port_no" is the fourth byte and it means the port number.
The Remote ID is 6 bytes in length, and the value is equal the DHCP relay agent’s MAC address. The DHCP Relay Configuration
screen is shown in Figure 4-2-11.

DHCP message when transferring to DHCP client. It only works under DHCP
relay operation mode enabled.
Disabled: Disable DHCP relay information mode operation.
Relay Information
Policy
Indicates the DHCP relay information option policy. When enable DHCP relay
information mode operation, if agent receives a DHCP message that already
contains relay agent information. It will enforce the policy. And it only works under
DHCP relay information operation mode enabled. Possible policies are:
Replace: Replace the original relay information when receive a DHCP message
that already contains it.
Keep: Keep the original relay information when receive a DHCP message that
already contains it.
Drop: Drop the package when receive a DHCP message that already contains
relay information.

4.3 Simple Network Management Protocol
4.3.1 SNMP Overview
The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management
information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.
SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network
growth.
An SNMP-managed network consists of three key components: Network management stations (NMSs), SNMP agents,
Management information base (MIB) and network-management protocol：
。 Network management stations (NMSs)：Sometimes called consoles, these devices execute management applications
that monitor and control network elements. Physically, NMSs are usually engineering workstation-caliber computers with
fast CPUs, megapixel color displays, substantial memory, and abundant disk space. At least one NMS must be present in
each managed environment.
。 Agents：Agents are software modules that reside in network elements. They collect and store management information
such as the number of error packets received by a network element.
。 Management information base (MIB)：A MIB is a collection of managed objects residing in a virtual information store.
Collections of related managed objects are defined in specific MIB modules.
。 network-management protocol：A management protocol is used to convey management information between agents
and NMSs. SNMP is the Internet community's de facto standard management protocol.
SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a response.
。 Get -- Allows the NMS to retrieve an object instance from the agent.
。 Set -- Allows the NMS to set values for object instances within an agent.
。 Tra p - - Used by the agent to asynchronously inform the NMS of some event. The SNMPv2 trap message is designed to
replace the SNMPv1 trap message.
SNMP community
An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where
information is sent. The community name is used to identify the group. A SNMP device or agent may belong to more than one
SNMP community. It will not respond to requests from management stations that do not belong to one of its communities. SNMP
default communities are:
。 Write = private
。 Read = public
Use the SNMP Menu to display or configure the Managed Switch's SNMP function. This section has the following items:

4.4.5 Port Mirroring Configuration
Configure port Mirroring on this page. This function provide to monitoring network traffic that forwards a copy of each incoming or
outgoing packet from one port of a network Switch to another port where the packet can be studied. It enables the manager to
keep close track of switch performance and alter it if necessary.
To debug network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame analyzer can be
attached to analyze the frame flow.
The Managed Switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol analyzer
or RMON probe to this port to perform traffic analysis and verify connection integrity.
Figure 4-4-5 Port Mirror application
The traffic to be copied to the mirror port is selected as follows:
All frames received on a given port (also known as ingress or source mirroring).
All frames transmitted on a given port (also known as egress or destination mirroring).

4.5 Link Aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs). Port
Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy.
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media types
(UTP/Fiber, or different fiber types), provided they operate at the same speed.
Aggregated Links can be assigned manually (Port Trunk) or automatically by enabling Link Aggregation Control Protocol (LACP)
on the relevant links.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port attributes to
a non-aggregated port, including auto-negotiation, speed, Duplex setting, etc.
The device supports the following Aggregation links :
Static LAGs (Port Trunk) – Force aggregared selected ports to be a trunk group.
Link Aggregation Control Protocol (LACP) LAGs - LACP LAG negotiate Aggregated Port links with other LACP
ports located on a different device. If the other device ports are also LACP ports, the devices establish a LAG between
them.
Figure 4-5-1 Link Aggregations
Page 99
User’s Manual of NS3550-24T/4S
99
The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner
Systems that require high speed redundant links. Link aggregation lets you group up to eight consecutive ports into a single
dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode,
more detail information refer to the IEEE 802.3ad standard.
Port link aggregations can be used to increase the bandwidth of a network connection or to ensure fault recovery. Link
aggregation lets you group up to 4 consecutive ports into a single dedicated connection between any two the Switch or other
Layer 2 switches. However, before making any physical connections between devices, use the Link aggregation Configuration
menu to specify the link aggregation on the devices at both ends. When using a port link aggregation, note that:
The ports used in a link aggregation must all be of the same media type (RJ-45, 100 Mbps fiber).
The ports that can be assigned to the same link aggregation have certain other restrictions (see below).
Ports can only be assigned to one link aggregation.
The ports at both ends of a connection must be configured as link aggregation ports.
None of the ports in a link aggregation can be configured as a mirror source port or a mirror target port.
All of the ports in a link aggregation have to be treated as a whole when moved from/to, added or deleted from a VLAN.
The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.
Enable the link aggregation prior to connecting any cable between the switches to avoid creating a data loop.
Disconnect all link aggregation port cables or disable the link aggregation ports before removing a port link aggregation to
avoid creating a data loop.
It allows a maximum of 16 ports to be aggregated at the same time. The Managed Switch support Gigabit Ethernet ports (up to 12
groups). If the group is defined as a LACP static link aggregationing group, then any extra ports selected are placed in a standby
mode for redundancy if one of the other ports fails. If the group is defined as a local static link aggregationing group, then the
number of ports must be the same as the group member ports.
The aggregation code ensures that frames belonging to the same frame flow (for example, a TCP connection) are always
forwarded on the same link aggregation member port. Reording of frames within a flow is therefore not possible. The aggregation
code is based on the following information:
Source MAC
Destination MAC
Source and destination IPv4 address.
Source and destination TCP/UDP ports for IPv4 packets
Normally, all 5 contributions to the aggregation code should be enabled to obtain the best traffic distribution among the link
aggregation member ports. Each link aggregation may consist of up to 16 member ports. Any quantity of link aggregations may
be configured for the device (only limited by the quantity of ports on the device.) To configure a proper traffic distribution, the ports
within a link aggregation must use the same link speed.
