3.1.1 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.
3.1.2 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 switch console (serial) port.
When using this management method, a null-modem 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:
384,00 bps
8 data bits
No parity
1 stop bit
You can change these settings, if desired, after yo
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.
u log on. This management method is often preferred
3.2 Web Management
The switch provides a browser interface
you set up your IP address for the switch, you can access the switch's Web interface applications directly
in your Web browser by entering the IP address of the switch. You can then use your Web browser to list
and manage switch configuration parameters from one central location, just as if you were directly
connected to the switch's console port.
Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape Navigator 4.03 or
later.
that lets you configure and manage the switch remotely. After
3.3 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the switch. This
manae SNMP Network Management
gement method requires the SNMP agent on the switch and th
Statiunity string. This management method, in fact, uses two community strings:

3.4 Protocols
The switch supports the following protocols:
Virtual terminal protocols, such as Telnet
Simple Network Management Protocol (SNMP)
3.4.1 Virtual Terminal Protocols
A virtual terminal protocol is a software program, such as Telnet, 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 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
#Note:
terminal directly to the console (serial) port.
3.4.2 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.
3.4.3 Managemen
ll of the management application modules use the same Messaging Application Programming Interface
A
(MAPI). By unifying management methods with a single MAPI, configuration parameters set using one
method (console port, for exa
example, SNMP agent of Web browser).

4.4 VLAN Configura

A Virtual a logical nllows you to
isolate nety meme traffic from the same VLAN members.
Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network
devices tr Layer 2 switch
physically.
The WGSD-1022 supports 802.1Q (tagged-based) and GVRP Dynamic VLAN setting in web
managemeault configuration, VLAN support is “802.1Q”.
IEEE 802.1Q VLANs
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which
enables them to span the entire network (assuming all switches on the network are IEEE
802.1Q-compliant).
VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets
entering a VLAN will only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are
members of that VLAN, and this includes broadcast, multicast and unicast packets from unknown
sources.

VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN will only deliver packets
between stations that are members of the VLAN. Any port can be configured as either tagging or
untagging. The untagging feature of IEEE 802.1Q VLAN allows VLAN to work with legacy switches that
don't recognize VLAN tags in packet headers. The tagging feature allows VLAN to span multiple
802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled
on all ports and work normally.

4.7.5 Port Security
Work security screen (see figure 4-32) can be increased by limiting access on a specific port only to
users with specific MAC addresses. MAC addresses can be dynamically learned or statically
configured. Locked port security monitors both received and learned packets that are received on
specific ports. Access to the locked port is limited to users with specific MAC addresses. These
addresses are either manually defined on the port, or learned on that port up to the point when it is
locked.
When a packet is received on a locked port, and the packet source MAC address is not tied to that port
(either it was learned on a different port, or it is unknown to the system), the protection mechanism is
invoked, and can provide various options.
Unauthorized packets arriving at a locked port are either:
Forwarded, Discarded with no trap, Discarded with a trap,Cause the port to be shut down.

4.7.7 Storm control
A BroadcastStorm is a result of an excessive amount of broadcast messages simultaneously transmitted
across a network by a single port. Forwarded message responses are heaped onto the network, straining
network resources or causing the network to time out.
The system measures the incoming Broadcast and Multicast frame rate separately on each port, and
discard frames when the rate exceeds a user-defined rate.
The Storm Control page provides fields for enabling and configuring Storm Control. The screen in Figure
4-34 appears.

4.8 QoS
Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort
traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network.
This ensures that network traffic is prioritized according to specified criteria, and that specific traffic
receives preferential treatment.
And Cos Settings, Queue settings, Dscp Settings, Bandwidth, Basic Mode, Advanced mode are
provided.
4.8.1 CoS Settings
The terms Class of Service (CoS) and QoS are used in the following:
CoS provides varying Layer 2 traffic services. CoS refers to classification of traffic to traffic-classes,
which are handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p
service that classifies flows according to their Layer 2 priority, as set in the VLAN header. QoS refers to
Layer 2 traffic and above. Qofic class.

The device supports the following Spanning Tree versions:

• Rapid STP, which detects and uses network topologies that provide faster convergence of the
spanning tree, without creating forwarding loops.
•Multiple STP, which provides full connectivity for packets allocated to any VLAN. Multiple STP is
based on the RSTP. In addition, Multiple STP transmits packets assigned to different VLANs through
